Shimano recently filed an application with the United States Patent Office that's raising eyebrows and all sorts of questions.
The patent appears to outline a completely interconnected, electronic component system—as in, you hit a button that drops the seatpost and the suspension travel and damping automatically change as well. Pure conjecture here, but if I were a betting man, I'd guess that lowering the seatpost as you begin to drop into a steep descent might automatically increase your travel and reduce the compression damping on your fork and rear shock. Think of it as an e-version of
BMC's Trailsync dropper.
Bombs away.
That's what it looks like from here, at least. Patents are a strange beast to wrestle with; they are at once incredibly detailed and obscure. Companies need to set precedent and protect their emerging technologies without exactly giving up the goods. It's a weird, linguistic dance. You can pore through the patent application
here, but the bit about suspension travel, damping and seatpost interconnectivity is evident in the patent filing.
Shimano has never been a company bent on courting controversy, so I wasn't surprised by their response when I requested an official company statement on the patent.
"Shimano is constantly in development of new products, but does not comment on rumors, innuendo or speculation about products whether they are in development or not.”
Well, okay then. The company doesn't want to deal in speculation, but I will...it's in my job description.
An Electric World...It's ComingIt's not like Shimano has been hiding their electric intentions. They debuted Di2 for road bikes in 2009 and rolled out e-XTR in 2014. We've tested the stuff extensively. But as we noted in
this double header XT Di2 review, while novel and accurate, electronic shifting hasn't been a game changer in the dirt world. It seems like a fair bit of wires and hassle to accomplish a task that a $3 steel cable already does pretty damn well. It kind of makes you think that maybe the end game was always something much bigger than moving a rear derailleur left and right.
Likewise, electronically-activated suspension has been around for a good long while now. K2 had its "Smart Shock" back in 1997. Fox rolled out its electronic iCD suspension waaay back in 2012. Magura has had acceleromator-equipped suspension for years as well. But getting those suspension components to "talk" to non-suspension components? That's a new trick, if not a logical progression. That patent suggests it may soon also be a reality.
But the patent indirectly raises another question: Will Shimano's electronic dropper seatpost communicate with Shimano-branded suspension? Will Shimano become a major player in forks and rear shocks? When you consider that their biggest rival, SRAM, has its fingers stuck deep into the suspension pie, it seems odd that Shimano would continue to steer clear of the squishy-bits business. Might Shimano's moment arrive in the form of electronically-activated suspension that "talks" to their e-dropper post? Who knows. Shimano isn't in the business of conjecture and innuendo, but you're free to go whole hog.
Conjecture away.
...on this full suspension rim-brake road bike?

i really don't get it.
there are soooo many other things that could be written and commented on about our lil mtb world.
people, places, companies,newbies, vets, racing, freeride, nutrition, grass rooots racing..........it just goes on and on..........
how about some killer interviews with olympians or paralypians that use mtb for cross training?....or mx/sx stars.?...............i see ken roczen is sponsored by canyon these days..........
soooo many other cooler things to write about and discuss.
but no, click bait wins out.
They're outselling downhill, enduro, freeride and slopestyle bikes combined by a large margin.
what a patent covers is defined in the "claims". Unfortunately, sometimes those are not unambiguous, and that is when lawyers get involved.
The main point I am getting at is that the drawing is really of no consequence. What matters is the "claims". The drawing is there to attempt to clarify what the claims are. It is not the drawing which creates the ambiguity. Shimano's drawing with wheels and suspension out of scale is of no consequence.
Also, if I could point to a product which was on the market which used one of the claims, then some or all of the patent would be invalidated. One unfortunate thing is that if a patent dispute goes to trial you can be sure that one or both sides will exclude anyone who they believe has a background that allows them to understand what the argument is.
Wireless shifting, droppers (and braking) would be f*cking awesome!
it's happening. get used to it.
Think of how clean the bars could be!
The first claim in the patent says it all:
1. A bicycle control device comprising: an electronic controller that controls an operational state of a bicycle component based on at least an operational state of a bicycle electric assist unit, the bicycle component including at least one of an electric suspension and an electric adjustable seatpost.
As far as I can see, all the other claims are rooted in claim 1.
I am an engineer not a patent attorney, but I have been involved in the patent process up to my wallet. After a very quick read it looks to me like this patent covers an integrated suspension control module for a bicycle with an "electrical assist unit", so all the hardcore technophobes can go find something else to worry about.
As an aside, I have just installed an electronic shift group (Campagnolo EPS) on my road bike. It is still too snowy to ride it on the road, but on the test stand I really like what I am seeing. Uniform force to actuate the shifts, multiple shifts by holding the lever in the actuate position, the front derailleur trimming automatically.
And if it fails I can shift manually at a stop. I had to do that last fall when my SRAM shifter on the tandem failed on tour in the middle of nowhere in Scotland. I just don't see what there is to hate about electronic shifters. They will be as good or bad as the design, craftsmanship (stow it JustinTrudeau), and materials allow.
part 40 does indeed reference an electric assist unit.
I copied this from a patent attorney's web page. Not sure if it makes the whole thing more clear, or less:
The claims are the heart of a patent, in that they define the limits of exactly what the patent does, and does not, cover. That is, the patentee has the right to exclude others from making, using or selling, only those things which are described by the claims.
Since the claims all refer to an electric assist unit, it seems to me that this patent is about e-bikes only.
Di2 has an indicator for when it is running out of charge... when your car's low fuel light comes on, do you ignore it and go for a drive, then complain when you run out of fuel?
I just bought a aftermarket add on electrical shifter for my tandem. It uses small cells and I can easily carry a spare set with me.
I am eagerly awaiting Shimano's answer since it will not doubt be solid, and most likely cheaper than SRAM alternatives.
That said, my money is on a year tops. A decade out who knows what will be the average drivetrain
Best case: 4-5 years
Worst case: a decade
I ride my SLX 1x10 for 4 years now with 80€ spent in cassettes and chains- still works flawless.
Currently with sunrace 11-42 and the oneup upgrade for the der.
Currently deciding between Zee 1x10 or SLX 1x11 for my new bike...
So yeah I guess that would make it fake news - since it doesn't exist.
Would not surprise me if shimano is planning to integrate and provide batteries and stuff for live valve
The benefit of electronic shifting is... mmmm.. there is a battery to worry about, environmental impact of battery and battery disposal, additional supply chain constraints (probably sea freight compared to air freight for no batteries), additional change control, more parts to fail (lower reliability), more expensive... looks like marketing v engineering. (I work in R&D so know the battle all too well).
There doesn't need to be a cable between the shifter and the derailleur. RF for short distances can work well with a fairly low power consumption. With an RF system, the shifter is 2 buttons in a case with a small RF circuit.
It is much simpler than the abomination I currently have on my bars. My SRAM shifter failed on Skye last fall, and since it was not Shimano I couldn't find a replacement since the one bike shop that might have had one was closed.
Using a removable cell adds some complication, like sealing against water intrusion, but allows the components to be shipped and locally sourced cells added. Li Ion cells can be safely disposed of, and much of the material can be reclaimed.
And on a long travel suspension frame, an RF based shifter eliminates possible issues with cable flex and pinch. The cost is higher, and reliability will depend on the design and workmanship of the manufacturer.
First on the article, it could lead to something big... or, it could be a matter of "patent it just in case someone else goes down this path", and they may have decided not to, possibly. Either way, really neat little blub, I love stuff like this.
Regarding the vid:
I just wanna say, I love what KS is and has been doing as a company. They started out making cheap parts en mass quantities as recently as 1991... look at them now, only 27 years! They've been a great alternative at a nice price point for a while now, and they're rolling out with new stuff year in and year out- keeping up with the "big dogs". I have a lot of respect for them as a company. I hope they're able to grow their market share so they can keep coming out with nice stuff.
... and ideas for connecting suspension with dropper adjustment with the possibility to link it to gear selection/cadence/...based on a logic have been pointed out in the public domain for at least the same time as electronic adjusted suspension, gearing and droppers exist.
Leaving me with 13 gears to work with.
You are so preoccupied with hating ebike that you hate anything you might deem loosely connected to it.
You basically have created right-wing bike politics.
Only if there was a fox News equal for mtb news...
They are popular and becoming even more so around the world.
And by the way try sticking a stick in my spokes and see what happens.
I don't have the money for an electronic shifting system, but my trip in the ambulance and 7 hours in the ICU when a ghost shift at full sprint sent me OTB into a concrete curb tells me I might be tempted by one, if only to avoid the pain of a shoulder blade broken in 3 places and face like Frankenstein's panda.
I can dream, maybe when my teenage daughter stops spending all my money on her education!
Sort of like when a crazy chic attacks a bus driver and is labeled a feminist on fox news.
But in reality she's just a crazy bitch.
Clearly a ebike isn't a moped anymore then a motorized shopping cart is a car.
But labeling it that helps you justify yourself.
At the same time, I wouldn't mind trying electronic shifting, seems cool. The problems with gear housing are pretty much gone with decent housing running full length and coated cables, though.
Higher gearing, seat up (uphill climbing) stiffer shock?
Low gearing, saddle down (dh) shock open...
FSA guy: Errrr..... it's the way the industry is going.
Sounds legit.
I'm all in for Team Blue and Team Red ,Box, Pinion, MRP and all the rest.
From the patent "The electric assist unit 40 includes an assist motor (not shown) and assists the rotation of the cranks 24 using the assist motor."

Shimano has given up on downhill.
They refuse to release carbon cranks (which right or wrong is an expectation by the majority of people buying high end bikes and high end parts)
Because they refuse to release 12 speed and the consumer has spoken loud and clear that expect it, Shimano has roughly a single digit share in the OEM market of >4k bikes. Not a scientific number, but look at how high end bikes are speced....
And when when they do come out with 12 speed.... if you think the s#*t storm over DUB bottom brackets was bad, wait until Shimano's new free hub standard comes out.
Shimano is a dying company.
The word on their balance sheet shows profits of 270, 350, 512, 760 and 510 million dollars over 2012 to 2016.
Sram's revenue, that's revenue, in 2016 was 45 million; less than 10% of the profit made by Shimano.
Not prioritising our favoured sport?
Maybe.
Dying?
Hardly.
People always bring this up. I could care less about the low end junk.The people that buy that junk don't care that it is Shimano and they won't care when it's generic Chinese stuff that is cheaper than Shimano.
Right now is Shimano is 1980's GM letting Cadillac wither away while making each successive generation of mid-size car crappier and crappier. Awesome Corvettes and Trucks didn't save them from going bankrupt.
I used to be just as much a Shimano fanboy as the rest of you. It was all I ran on my bikes and I convinced my self it was better. It's not and the glory days are over.
Most patents filled are not brought to reality, it just stops other companies.
Errrr ever heard of Saint.. Zee....?
Carbon cranks an 12 speed.. Its well known in the industry that shimano doesn't work on anything they feel is unnecessary
A dying company yeeeaaahhh roight
Maybe not. www.pinkbike.com/photo/15610926
I suppose, if, as you say, their bicycle business is dying, they could quit the business and 'go fishing'. fish.shimano.com
But in any case, if you are so much of a fan boy that you have to pull put their stock price as the reason their stuff is still good, you lost. Not saying it doesn't have it's positives, but compare an XTR cassette to a XX1 cassette and tell me Shimano isn't a company that is mailing it in.
I don't know a lot about fishing, but from what I have heard anecdotally, their new stuff is "value engineered" and not up to the standard of their old stuff.
Saint and Zee haven't been updated since 2012. Think of what your DH bike looked like in 2012...
You are funny.
Enjoy your world view.
Don't darken mine in future if you don't mind; It would be appreciated. Cheers!
The web is full of people who think they know better and who are utterly convinced of the universal truth of their views and opinions.
Like Shimano is a dying company.
Even in the face of financial information and the views of the market as expressed through the share price.
Schooled?
Yeah, right. Welcome to the deluded world mate. Enjoy it. Don't you bother conmentating on anything I post here either thanks.
I have no time for people who cannot take on factual information.
