OneUp Components Granted Patent for Wide Range Sprocket, Cassette

Apr 27, 2015
by Mike Kazimer  
The last few seasons have seen scores of riders decide to ditch their front derailleurs in favor of 1x setups, a configuration that became more feasible with the advent of SRAM's wide range 1x11 drivetrain, which was recently followed by Shimano's introduction of an 11 speed gruppo of their own. But turning it up to 11 can be a pricey proposition, and that's where companies like OneUp Components come in, offering add-on cassette sprockets that allow riders to expand the gear range of their 10 speed cassettes by removing one of the smaller cogs and installing a 40 or 42 tooth sprocket to create an easier climbing gear. Soon after OneUp launched their line of drivetrain solutions a number of other manufacturers entered the market after noticing that there was a sizable demand for cassette conversion kits.

OneUp Components was recently granted a US patent for their cassette sprockets, as well as a wide range cassette. The patent describes “a bicycle sprocket for use with a multi-gear rear cassette that improves the gear range

of the cassette and can be used with most conventional drivetrains designed for use with a ten sprocket rear cassette,” along with “a bicycle multi-gear rear cassette having an improved gear range that can be installed for use with most conventional drivetrains designed for use with a ten sprocket rear cassette.” OneUp doesn't currently offer a complete wide range cassette, but the fact that they applied for and received a patent for one is a strong indication that they may have something in the works.

OneUp Components have stated that they feel there are several companies producing products that infringe on their patent, but according to the Squamish, BC, based company, “We'd like to give these parties a chance to evaluate their designs against our patent. We would be happy to discuss a mutually beneficial licensing agreement with any company that does deem their design to be covered by our patent.” OneUp was vague about what the costs would be for a company to license the design, but did say that the amount was negotiable.

 Very high risk of patent trollage. The market for range expanders exploded because no one did the dirty. Everyone got to stt at the range expander table and the market decided which was worthy of business. Now it comes down to a piece of paper. I wonder if spesh will buy them up....

 I'm not trying to start an argument at all. Just saying what I see. What I see is a comments section that used to be interesting becoming more and more stupid by the day. I get that you are just trying to add some humor to your day, but so are the kids who hang out in the shop I work in all day sniggering to each other about fart jokes and fat people. Whatever floats your boat I guess, but for everyone else who finds the whole thing little more than irritating, it gets old really, really quickly. I have remained fairly close mouthed about it for a couple of years now, but seeing as Hodges voiced a similar opinion to mine, and quickly got neg propped until his comment disappeared, I just thought I'd let him know I agree. The puns got old a long long time ago. Some of the best were vaguely amusing at first, but the majority of them are a bit desperate, it really has run its course now... If you really do love the puns, I am sure you can find some pun based website to frequent. This is a bike website however.

 We're stoked that Pinkbike cares enough about us to run this article. However, as we expressed to the editor, we don't feel that it is particularly news worthy. Shimano, SRAM, Race Face, Hope, E-13 and Wolftooth all have patents or patent applications for various designs. Not taking the necessary steps to protect our own ideas puts us in the unfavourable position of having our unique designs duplicated while our much larger competitors block us from their novel concepts.

 Patents can be both offensive (Sue everyone in Sight and damn the conSequenceS) or defensive (use your patent to defend yourself against others who also have general patents.

Either way you look at it it's a sign that a company is looking to the long term future and being prudent if they have the wherewithal and knowledge to look at patents.

 I think it's interesting and refreshing to see a smaller company get a foot in to the door of this very competitive market, so I think it is newsworthy, everyone likes an underdog! It's also reminding people in this online community about OneUp, which can't be a bad thing!
  • 24 20
 So the patent is based on the machined feature that spaces the cog beyond the largest cog on the parent cassette? How was this patent granted? I do not see anything unique from what's already on the market. So this patent will prevent other companies from selling here in the US? I hope OneUp has the funds to defend this patent.

 Yeah so first of all, exactly what DARKSTAR63 said. You didn't want everyone to know what a pack of stupid douchebuckets you are.

Patents are all totally fvcking stupid, the whole process should disappear, but some patents are stupider than others & it kinda looks like this may be the pinnacle of stupidity right here. The way this article reads to me is that two of the "Big 3 (all of which start with "S")" greatest evils in the bike industry already came up with an idea, that you turds subsequently copied, maybe slightly modified in some trivial & insignificvnt manner & then applied for a patent on it. A patent on someone else's idea? O.o It's a stupid thing to patent in any case, but this is sooooooo fvcking stupid. So ambiguous & all encompassing. Like anyone that makes a cassette with "improved" range (whatever the fvck that means) is in violation of your legally binding stupidity? GTFO! Fvckin' stupidiotards.

What if everyone patented everything? Like if RS patented the telescoping fork? Answer the inverted telescoping fork? What if someone patented the whole bicycle? The car? The microchip? What sensible way do you define the limits of what is & isn't patentable? It's totally fvcking stupid. Build decent products, for decent prices, backed by decent customer service & you'll probably do fine. Look how many pedal brands, bar brands, stem brands etc. there are out there. You don't see anyone patenting things like hollow chain pins, titanium fasteners, telescoping seat posts etc. Those are things that actually have some kind of compelling advantage to offer & anyone is free to produce them however they like as much as they like.

 I like how some people have been dropping "S" bombs targeted at the 3rd biggest evil in the industry. Take note, because what that is, is a sign that douchebaggery isn't easily forgotten.

Get over yourself, knock off the greediness & do things to make the industry, the sport & the world a better place for everyone, or please just fvck off. :/ This rant isn't just directed at OneUp, it's for all the a*shole profiteers out there. The best products in the world are "open source". Sometimes some idiot comes along all "patents are necessary to stop an idea getting stolen, protect IPs, blah blah blah" yet so many more things have not been patented & numerous companies do just fine manufacturing & selling the same things. Pick anything, toilets, blenders, coffee makers, music players, TVs. Fvck me, the guy that invented the wheel sure would have been kicking himself for not patenting it ya think?? :s

Lets see how @OneUpComponents plays this one, and what the specifics of the patent say, and who they think is infringing before jumping to conclusions here.

 Hey OneUp, while your listening do you think you can consider doing a steel 42T cog? you know, for durability. Thanks!
  • 27 5
 It seems there may be some misunderstanding about what exactly we have patented here. We have not patented something as generic and ambiguous as a 'wide range cassette' or an 'expander sprocket'. Our patent is for a very specific set of features that OneUp was the first to, invent, market and patent. They are cited in claim 1 of our patent.

I Hope that helps,

 @richard01 -
A patent is only comes down to what is in the claim section, not what the pretty pictures look like or what is talked about. Basically, their awarded patent claim is a extra sprocket that works with existing drive trains that has teeth on the OD and an interface to the free hub on the ID. It has specific shoulders to maintain correct spacing.
The dependent claims, all below the initial claim, are supporting specifics. So basically, they've patented the application of making a single sprocket that is designed to work with existing multi speed bicycle drive trains. This is not about teeth design, or shape, whatever.
It's BIG to be awarded this. It reads to me like every manufacturer of is in violation...
I'm an engineer too that has about 5-6 patents, fwiw

 Unfortunately, I have to agree (somewhat) with freeride-forever. Patents hold back an economy, and typically benefit the few and rich at the expense of the many and little.

I don't hold anything against OneUpComponents, they have to do this to protect themselves against a big, mega-corporation that has a bigger legal budget than an entire smaller company like OneUp. The environment created by patent law forces companies to patent everything in sight before their competitors do. When markets are decided by the lawyers of big companies like "S" or a certain tech company that patented "rounded rectangles", the old and rich win and the new and innovative lose.

 @ErnieK thanks, trying to make sense of the patent is hard. That's what I understood it to read. When you say spacing are you referring to the spacing required for it to be spaced correctly with a standard cassette. Which is "unique".
  • 3 0
 @richard01 I think the spacing is the hub spacing on the bottom plus the shoulder spacing about half way up on the 42t that stabilizes itself against the 36t. I imagine the lever arm is getting pretty long with a 42T and 45t and realize the natural chain line is pulling the 42t "towards" the 36t.

 If a person or a company could not get protection for their intellectual property, then innovation would stop. It doesn't matter how insignificant the design, process, or product seems to be, its innovators deserve protection from copycats and ripoff artists. Find a way around their patent if you so desire.
  • 9 1
 I think patents don't favour the rich at all. Imagine if there were no patents available, and you had an invention that you were ramping up production on, and someone with more resources than you saw your idea, stole it, then took it to market before you. Patents protect you from that.

 They can be awarded a patent but it remains to be seen whether the patent is strong enough to withstand being challenged.
  • 2 1
 I think there is plenty of daylight shining through the wording of the patent. It VERY specifically describes their product, but does not make the description so broad that an add-on wide range cog could not be legally marketed by someone else. Two examples which came to mind: Claim 10 states that the item is made of a "metallic material" suggesting you could make the freehub interface and supporting arms out of CF and rivet a metal chain interface to this. OR, all of the full cassette descriptions illustrate the wide range cog as having its own interface directly with the freehub body (i.e. not connected to the rest of the cogs via a common spider, etc.)

I could certainly be wrong, and am the first to admit that these thoughts are the result of just one quick read of the patent, but it's looking to me that this is more of a defensive patent than an offenSive one. If the other makers of such products are careful in observing the specific details of this patent, they should be home free.

 @ErnieK
I think the question here is what is non-obvious about one-up's design, that isn't simply copying shimano's design just with a larger diameter. I wouldn't think the spacing is any different than the spacing the stock cog came with.

Getting the patent is one thing, but i would think in court they could be challenged on the idea that their idea was non-obvious. Did they or did they not simply make a larger diameter sprocket?

 I am not against Apple, nor am I against OneUp. The OneUp product is great and it was the first widely accessible. I have however problems with patents because what they really do is stop innovation and make things much more pricey for us (or for US for that matter ;-) ). In case of OneUp the patent law simply gives them opportunity to sell a piece of aluminium for $100 as long as they want, so they do not have to innovate anymore, just make money.

 History of the extention cog as far as I have followed it:
The first steel extension cogs started to appear on ebay in 2012 after people had bolted chain rings to their cassettes previously. General Lee came out roughly at the same time.
In April 2013 the first one made of aluminium I have ever seen appeared on a German massage board, a user there produced a small patch and I own one from this very first patch: www.mtb-news.de/forum/t/xx1-alternativen-diy.601751/page-57
Oneup posted their first ever post on facebook in late november 2013, showing their cog.
Then loads of others followed.

 There are a lot of them out there. In reading through the patent, there's a list of when these other companies products were made available to the public. For instance, Wolf Tooth was showing an add-on cog no earlier than Feb 2014 according to these references. OneUp either might have been doing it before everyone else, or at least got their patent docs through the system earlier than everyone else. Getting a patent like this is not inexpensive.

So, if other companies are using technology or a configuration that is covered under this patent, as they say above they can negotiate a "mutually beneficial licensing agreement with any company that does deem their design to be covered by our patent". Meaning: start paying or shut it down...or find another way around this patent.

 The part that surprises me is the "wide range cassette" ... how on earth do you patent something like that. The Cog I can understand, it's a unique idea, but to just patent a cassette the "expands range" particularly when this was not their idea at all but rather SRAM's just applied to a ten speed..... Sneaky.
  • 11 0
 I'm not a patent expert (but I do have to read them a lot for work) but it appears that you could easily get around the patent by using a cassette spacer instead of the integral spacer machined onto the sprocket itself. All of the independent claims in the patent claim "a plurality of space maintaining protrusions, each space maintaining protrusion integrally formed with and extending axially forwardly from an axially forward surface of a corresponding support arm".

So... maybe not the end of competition here.

 There is always the route Giant took with Dave Weagle, copy the thing, wait for the lawsuit and then spin it out and out and out until the guy you're copying runs out of money. I think OneUp are not unreasonable to be patenting their product, especially since everyone else was so eager to copy it, but it doesn't mean they're suddenly immune from a much larger company ignoring the patent entirely, then squashing them like a bug.

 It looks like OneUP is going to lose a lot of business with the new and cheaper 11 spd products coming out from Shimano and SRAM. People will not buy new 10 speed groupo and then convert it to a wide range. OneUp has to do something to continue to make money, and this patent will not help them much. They should be investing into new products if they want to continue to make money. Also, they should be happy with the money they made from the 10 spd wide range sprocket.

 Unless, of course, it's deemed an obvious extension of prior art. It's hard to argue that an 11-42 10 speed cassette is not obvolious given that there have been oodles of 11-36 10 speed cassettes. There's nothing original about extending the range, the reason it hadn't been done was not that it's innovative to do so, but that rear derailleurs traditionally couldn't handle it. Plus 11speed wide range cassettes are not fundamentally different from 10 speed ones, so they constitute prior art as well. And hacking apart a cassette to take out one sprocket in the middle and add a large one - that also seems obvious and not too far removed from individual replacement cogs. Shame on USPTO for granting these.

 This a limited ride for these guys anyways. Once their cassette wear out folks will be buying wide range 11 speed cassettes.

 Exactly. Once the new XT and GX get out, it'll pretty much kill the GC rings. I see very few people buying the 44/45 tooth from them, especially to modify a 200 dollar plus cassette. Some of us may refuse to move up to 11, but it's here to stay and now is affordable as ever.
  • 3 1
 @abzillah. I disagree with what I you say about them needing to be happy with the money they made. It is business and they have every right to corner the market in their favor; that's capitalism. However, you are correct in that the 10 speed cassette is now "dinosaur technology" and will probably not be seen spec'd on any bikes within a year or two. The patent was a defensive move to protect profits until the 11 speed fully takes over the market.

I don't foresee companies being sued by oneup for patent infringement. For a small company to waste a ton of money in lawsuits and lawyer fees would be foolish. They definitely have the right to say they can flex that muscle if needed though. And like others have stated, the patent is only for US markets.

 The innovative thing was the wider range for a cassette, which SRAM did when they came out with XX1. IMO, it isn't an original idea to toss a bigger ring on the outside of your cassette. The USPTO hands out patents WAY too often now. Also, I'm a jaded software developer, so I'm naturally leery of patents given out now, since they seem to be handed out for anything.

 Everything about your bike is the same as everyone elses. Stuff like this is as daft as Rockshox suddenly turning round and patenting the concept of suspension forks. The art is to make it desirable/better/status/more durable. It infuriates me that I have to pay more for a one up component than say from another brand. Thankfully I live in the UK so just buy Superstar ones which will probably be on offer for around £20 this weekend as its a holiday! I would not buy a One Up for the much extra cost. Riding up hill is boring. Why would I want to pay more to do that?
Come on One Up, inovate not suffocate.

 en.wikipedia.org/wiki/Patentability

Patentable: check
Novel: sort of check
Useful: check
Non-obvious: seems pretty obvious to me...

Non-obvious is defined as when a person skilled in the field (in this case mtb drivetrains) would not be able to solve the problem the patent addresses.

In my opinion it seems pretty obvious that if you want a lower gear ratio you can just add a larger sprocket in the rear or a larger one up front. In fact, it's about as obvious as the gear it replaces. There's nothing that innovative about swapping the side of the cassette that the gear is on.

Also, if other companies want to produce similar components it seems like all they would have to do to get around this patent is make it part of the cassette. Might be wrong about that, but patents are always convoluted.

 On the face of it, that's pretty lame. Good to know though. OneUp 'made hay while the sun shined' but with Shimano finally providing a XT 1x11 solution can't see that there'll be much of a demand for addon widgets that to date have offered compromised shifting performance anyway.

 IntoTheEverflow a US patent is not only very expensive its very difficult to obtain and you pay your lawyers whether you get it or not. If this is a product you want from another company the price will not be too much more for it (in US anyway). Fortunately Sram or whoever didn't want to spend the large sum of money to patent the whole driveline and prevent small companies from even producing this product until they had satisfied their investment. Then after a few years they would produce this product and license it just the same as OneUp will attempt to do now. If this really bothers you I wouldn't sniff around patent stories too much the industry is rotten w them but w out them many of these companies wouldn't even be in business...

 This is an interesting move.
I can only pass judgment on the decision based on what I will need/want in the future. My desire to move from 9 to 10 speed was based on more gearing. My desire to move from 3x to 2x was the terrain I ride, 2x to 1x, losing weight from the bike (and a bit of fashion If I am honest, I like it so this is ok!). Question - will I want to move to an 11 speed cassette at some stage? Logically I would say yes. Is this going to cost money, of course, but by the time I decide to do this my other components will need changing anyway.
Oneup have protected their interests for this moment in time which is great, a small company competing with the big boys. The main question for me is will I 'need' an expander when I eventually order an 11 speed shiram cassette/shifter/mech combo? Not sure...
  • 2 0
 @Mercian -> Agree, I'm pretty much in the same boat. I was one of OneUp's first customers. Their solution fit my need for that moment.

I see these expander solutions are merely temporary and will eventually almost die out as more affordable wide range grupos are specced on bikes, as they certainly will be (GX, XT, SLX eventually). Several companies will keep these items in their mix of offerings, but a company built solely around it won't be able to stay in business past another couple years........ which brings us to this article and the reason for attempting to secure a patent.

And I don't see any reason why SRAM/Shimano would purchase OneUp. Maybe if they're actually able to lock in some revenue from licensing but that might turn into an antitrust issue? Time will tell. I just hope it doesn't turn into a pissing match. The owners of OneUp went into business to fill a need in the market and make a living doing it, but to start a legal battle with Wolf Tooth, Kore, Hope etc. is likely going to hurt their image as those brands are well respected (and I'm not totally convinced there's even anything patent-worthy going on here). My 2 cents. We'll see how this plays out.
  • 6 4
 srprised you can actually get a patent for a gear gog unless it does something particularly different to what is already out there. I can't see how they will be able to inforce this unles oher company's xpanders are exactly the same. typical american patent system though.
  • 4 2
 The gear cog does change the function of the original 10 speed cassette. All other companies that do a wide range cog are using something similar to one up's cog.

I don't know what you mean by the "typical American patent system" comment though. A company should have the right to protect their technology from being copied. This protects that companies profits and also encourages innovation within the industry to come up with new and better alternatives.
  • 5 0
 I think you know what I mean by typical american. there is a reason why it will only be an american patent and not worldwide.
  • 7 0
 poah means that the American patent system is well-known for granting someone a patent on something when it's obvious that they weren't the original party to do the idea.
The UK patent system is set up so that if OneUp was granted this patent then eg WolfTooth turned up and could prove that they had done something very similar before the patent was granted then that patent is declared null and void. It's why companies in Europe will patent something before bringing it to market and prototypes are so closely guarded. If eg Hope were to file for a UK patent on their expander cog it would be refused on the grounds that A: they weren't the first to do it and B: it's widely available in the market. It's the same reason SRAM's Narrow/Wide patent wouldn't have been granted here as it is a technique that was used in old farming machinery in the 19th century.

I'm not saying one system is better than the other, just that they are set up differently. The UK system means you have to prove you have come up with a unique solution or idea and allows the people who have invested time, energy and money to protect their investment. The US system rewards the first person to file the correct paperwork once they have a working product. And yes, I have experience of applying through both systems: UK wasn't granted, US was.
  • 2 1
 @DaMilkyBarKid The patent system is what it is. The US is not really any different than anywhere else. You've cited a couple of different examples, however, there's unique circumstances for each. The narrow wide on bikes is an application patent. Application patents can take existing technology and apply it to something new and patent it. Regarding the expander cog (sprocket), they've made a claim about spacers. I'm thinking that the only way for manufacturers to infringe (IMO) are when they have the same stabilizing spacers on the radial support arms. Lastly, both countries have pre-existing art issues. If there is art and it has been commercialized, there will be no patent granted. There HAS to be an improvement or simplification to warrant granting a new patent. OneUp, and the USPTO, believes that something in the claims is unique and improves the existing sprocket art, hence they were granted the patent..

SUMMARY

One aspect of the present invention provides a bicycle sprocket for use with a multi-gear rear cassette that improves the gear range of the cassette and can be used with most conventional drivetrains designed for use with a ten sprocket rear cassette.

Another object of the present invention is to provide a bicycle multi-gear rear cassette having an improved gear range that can be installed for use with most conventional drivetrains designed for use with a ten sprocket rear cassette.

One aspect of the present invention provides a bicycle sprocket for use with a multi-gear rear cassette. The sprocket includes a chain engaging portion and a mounting portion, both having a generally annular shape about a central axis. A radially outward edge of the chain engaging portion comprises a plurality of circumferentially spaced and radially outwardly extending teeth for mechanical engagement with a bicycle chain. A radially inward edge of the mounting portion defines an aperture shaped to receive therein a freehub body. A radially outward edge of the mounting portion is radially spaced apart from a radially inward edge of the chain engaging portion. A plurality of spaced support arms, integrally formed with the chain engaging portion and with the mounting portion, extends radially outwardly from the radially outward edge of the mounting portion to the radially inward edge of the chain engaging portion. The sprocket further includes a plurality of space maintaining protrusions, each space maintaining protrusion integrally formed with and extending axially forwardly from an axially forward surface of a corresponding support arm.

 So here in Europe we can actually buy the products from other companies aswell?

For example when I replace my cassette I don't want to buy a new XT cassette for example and a loose Expender cog (/pay twice as much as neccessary). I would much rather buy a complete cassette that already goes up to 40T (or more).


Strange to see that first the product came onto the market, than other companies started producing it aswell or making their own versions of it, and only a while after that the patent suddenly came. I thought it was only possible to get patents before you release the product (defensive), not when many others already invested a lot of money aswell in their own products and than kick them in the face by not allowing them to sell all those already-produced products (offensive). This proces seems a bit weird to me, but in to be honest in the end I'm still happy that One Up Components started this proudct, so I do think they deserve some defense for it.
It would have been safer for their own image though if they would have done the patent when they released the product.

I just really hope this doesn't mean that I can't buy a complete wide range cassette when I will need to replace my current one.
If One Up comes with one that is not ridiculously priced, I would be happy with buying that one though Smile

Are you ashamed of what you have done now that it's out in the open. Bet you sat around the office bemoaning stupid patents at some stage or other of your product development too.

Why not give us a easy to understand layman's explanation of your patent(s)? Is it something to do with tooth profile? Ramps?
  • 3 2
 The original idea of these cogs was to offer a less expensive option the 11 speed wide range set ups. Now that 11 speed drive trains are becoming more affordable seems like an awful idea to patent your product and cause everyone else that helped you create the wide range 10 speed movement to pay you for the rights to make what they are already making. Seems like a great way to mess up a good thing.

 Not sure why everyone hates on patents. Companies need to protect there innovations no matter how small. Unless it creates a monopoly on a product category it really doesn't raise prices or stifle innovation - in fact arguments can be made that it can lower prices and allows innovation.

Imagine you are oneup components - you have created the idea of this add-on component and think people want to buy it for given price. To make it at set price you need to invest in new manufacturing equipment, employees, facilities, etc. Are you going to risk investing all that time and capital if another savvy competitor can come in, patent the idea or some necessary design subset that makes the idea work and shut you down or get a court to order to have your profits garnished due to infringement on what was really your idea and your hard work. Of course not you risk losing everything and being in huge debt - if this was the case no one would spend the time to innovate and invest in manufacturing technology and resources that can drive down price.

To think that all these companies & people that start companies should take that risk of a time and money investment into a new idea/product and not be protected is really ridiculous.
  • 1 0
 JG - I like your points. But some of us armchair engineers are not yet convinced that there's anything worth patenting here. When OneUp entered the scene my first thought was they'll Ride the Lightning for a couple years and then be done. Get in, make a couple bucks, get out, then on to the next opportunity. And their business can be virtual. Design and marketing from home. Manufacturing in Asia. Under slightly different circumstances I agree with you, but it's not like they perfected the elusive gearbox and are manufacturing it locally in BC.
  • 2 0
 The innovation here is small and nearly insignificant. As I understand the claim (I didn't read it) is on the spacing feature of the design and however small it allows 2 things - the proper chain spacing combined with a larger surface area to spread the load onto the free hub and reduce flex of the cog. Yes this is a almost obvious design feature, but the patent office seems to think it is unique and new enough that it warrants a patent (was this an application patent? if so they think it warrants it for this application). If they can get it that means their competitors can too and they are at risk of not protecting the design they put together.

I think that the real question here is should the patent office have given them the patent for something so small and obvious (and specific to cogs on a bike cassette, because this is hardly the first time a spacing ledge has been used on a gear). Sometime patents are reversed by courts - which sucks to involve lawyers but what else are you gonna do? In this case the court could find that the design feature or innovation was not novel enough and reverse the patent.
  • 1 0
 I guess it depends on the intent for getting the patent. To stop other small companies like themselves ok but they won't stop SRAM or Shimano from getting into the wide ratio 10 speed game. Seeing how Oneup's design is based off Sram and Shimanos' I don't see how this patent is defend-able. Oneup certainly can't afford to go up against Shimano who has been doing this exact range extender thing for decades with their mega range cassettes and freewheels. There isn't a new idea here.

The problem is, if the wheel was invented today, somebody would at once patent two, three, and four wheeled vehicles. Probably someone who never intends to build any kind of vehicle himself. We would end up with five wheeled bikes and seven wheeled cars, because everybody would just try to find a way not to pay any license fees...

I use OneUp's product but am not yet sold on why anything about my 42t monster cog needs a patent.

Just because someone doesn't take their opinion to the nth degree and apply it as a blanket across every aspect of their life doesn't make them a hipocrite.

 F all of this, it is all good, product innovation is all good, it cannot happen without the patents (good on One-Up for causing progression and new development), otherwise there is no reason for schmucks like you and me to try and progress a new idea, if big brands drove the market, we would all be riding the crap they developed 20 years ago. Innovation is always going to come from small companies with new ideas, the big brands can always make money from the status quo, the more things stay the same the better things are for them.

Now listen to this, it will either make you believe or not, things changed in the 90's, before and after we thought.

For whatever reason it won't be Shimano or SRAM who both have the technology to do an offroad internal hub and it won't be Box either so how about it Oneup?

Maybe you could also let us spec our own cassettes with fewer than 10 cogs for those of us who want them.
  • 1 0
 Main reasons is that internal hub gearing is less efficient & extra weight over back wheel
  • 2 0
 Have you spent much time riding one? The shifting on the Alfine is excellent. The shifter doesn't get tighter like a derailleur does when the spring gets stretched. You can shift any time as many gears as you want.

As for efficiency people forget the more lateral offset between the chain ring and cog there is, in other words the worse your chain line is the less efficient the system is. If you spend much time working on systems with fewer cogs than 10 or 11 you would know just how much friction there is when you are on the larger cogs furthest from the centre line of the chain ring.

The are heavy but both the efficiency and weight could be improved if someone put their mind to it.

 Maybe I should buy that 41T eBay cog before it disappears forever.
