Sam Hill would be fined for Spandex Doping today. Will the
speed advantage of 650B wheels also fall under scrutiny? Should DH Bikes be Restricted to 26-Inch Wheels?
Pre-season tests comparing the mid-size 650B wheels with their conventional 26-inch counterparts has not been promising for those in favor of the latter. Fox Racing Shox, has been testing its suspension concurrently with teams that are outfitted with 650B and the report is a time savings of over a half second a mile. Intense reports better. Strava times on their very technical home course varied between three and nine seconds better on virtually identical bikes and builds. Recently, Pinkbike has done side-by-side testing of 650B and 26-inch DH bikes with comparable results. With the top five riders often finishing within two seconds of each other, all eyes will be watching the first few WC DH events to see if those preseason results will translate into race-winning performances. If they do, trouble may loom on the horizon.
The UCI, in its infinite wisdom, has repeatedly banned technological improvements like aerodynamic shapes and body positions, and enforced minimum weight requirements to many racing bicycles in an effort to minimize the impact of mechanical advantages in order to produce a version of cycle racing that is man versus man. The ban on skin suits for DH was based upon the supposed evidence that Tracy Moseley may have shaved one second or more off of her time while winning the Australian WC DH by Spandex Doping. Those in favor of the ban, argued successfully that ballistic nylon parachute pants and size triple-X Moto-style jerseys flapping in the breeze should be mandated
pret-a-porter for Pro DH racing. Granted, motocross gear looks pretty butch, but arguably, the Moto style was adopted without technical consideration and thus, the ban effectively curtailed the future development of kits specifically engineered for the needs of DH competition in the name of current fashion.
Logan Binggeli and KHS first put the stamp of approval for 650B wheels on DH bikes with his third place performance at the 2012 Red Bull Rampage. This season we will see if the mid-size wheels will do as well in World Cup DH competition.
Of course, this is all speculative, because as far as we know, the UCI is not considering a wheel-ban at this time. That said, if the UCI is silly enough to consider a useless visor to to be mandatory safety gear, or to force a no-spandex ruling, then it should come as no surprise that somebody might, at this very moment, be successfully pushing the UCI behind the scenes to ban alternative wheel sizes. Spandex became a banned substance after it was suspected to provide a mere, one-second advantage. My God man, if 650B wheels could give a guy a three-second advantage at Fort Bill, it would be like, um, CHEATING! I am sure that some would agree whole-heartedly. Locking in 26-inch wheels for downhill bikes may be OK, provided that it could be proven that the present DH bike has reached the zenith of its performance, but that is highly unlikely.
Intense has been testing prototype 650B DH bikes for
nearly a year with favorable results. This season, a full
complement of DH forks, wheels and tires are available,
so it's going to be no-holds-barred racing. Have DH Bikes Reached Their Pinnacle?
The proof that there is a lot more performance potential waiting to be unlocked from existing DH bikes is laughably illustrated by the fact that the simple addition of 38 millimeters to the diameter of the wheels does actually make a difference. By comparison, the invention of a larger diameter wheel for DH makes accepted technology like remote-adjust suspension and dropper posts seem like rocket science.
My opinion is that mountain bike racing is an equal blend of mechanical and human kinematics - especially so for downhill - and that there should be no restrictions imposed upon technological improvements to the bicycle beyond safety considerations. I also think that the DH bike, as we know it, has a lot of potential for improvement. If the 650B wheel does become a game-changer this season, I would much rather see it inspire further innovation than to evoke a knee-jerk response from rule-makers and become the line in the sand where significant DH development was stopped in its tracks.
Take the Pinkbike Poll
The point I try to make is, that with 26" wheels everyone has to fight trough rock gardens equally. Now someone turns up with bigger wheels and says "Haha, it's easier and faster this way". It's a quite stupid argument. The point is not to make DH easier and faster, but to make it more challenging! If we're about to make DH more "fast", why not modify all tracks to be like South Africa?
was sceptical about 650b taking off at first but i genuinely believe they will soon replace 26 inch wheels. Every company is bringing them out now and all tests are showing them to be a little bit faster but more importantly the testers and people riding them say they dont notice a difference in how the bike handles in comparison to a 26er. So I cant see any logical reason that 650b wont be the new standard. We all want better bikes don't we?
Banning it at WC level would be crazy as it would stop development of them. If there is that much of a clear advantage for bigger wheels then the teams not running 650b wheels will do so next year.
I don't understand this argument, I assume you are totally fine about new suspension designs and dampers that are also intended to make things smoother and more efficient for the rider, but when it comes to wheel size, there is not allowed to be any progression.
As far as wheel size debate, you gotta ask yourself ...Can I ride like chriskovarik yet on 26 and flats? No? Then sit your ass down. Haha
Arguments like 250 vs 450 are mute. The best selling moto bike in the past couple years is the KTM 350. Why? Its easier to manage than a full on 450, and has more of the lightweight feel of the 250. Can anyone connect the dots here?
What if 650B is 1% faster and 10% less fun.
WC will use it. Manufacturers will put R&D into it instead of 26. They will sell a 1% faster bike and discontinue the 10% more fun bike (or put less R&D into it).
Maybe a 650B is just as much fun. But either way, when the manufacture has to spend resources on developing bikes for 3 different wheel sizes, this whole argument that bikes are expensive due to quantities of scale just gets a whole lot worse. Maybe there would be a DHR2 exo 3C by now if they weren't wasting time making moulds for 3 different sizes. Maybe there would be a new lower slacker lighter NomadC by now instead of a Tallboy and Bronson. Maybe the price would come down if there was only 1 wheel size.
For the record, I support the ban on fairings, skinsuits and visorless helmets. Otherwise we might see people wearing teardrop helmets, body fairings and sporting shaved legs by now. Not a good look. Not to mention, you would have to start paying for your favourite bike manufacturer to do wind tunnel testing and fairing design which would show up in the cost of your bike whether it came so equipped or not.
No rules to break here just yet in regards to wheel size but this is beyond blackbox vs privateer equipment. It may take a full season or more to get a fair look at it. i'm sure it will get screwed just like the true spirit of the enduro format will. hell, the uci can't even be insightful enough on matters concerning licensed/unlicensed qualis/events for their racers. good luck.
Imagine if a WC racer told his coach that he/she was faster on a 1996 yeti arc hardtail for, say, a South African track, do you think theyd let him/her ride it?
the uci is all about sponsorship money. part of the reason they considered banning wc riders from racing in unsanctioned races.
ASSUMING they DO NOT tame the circuit, let the best bikes win.
Just like bigger engines generate more power (450>250), bigger wheels roll over stuff easier. And as wheels are the almost the "base" of the bike, it kinda is like a bigger engine on a MX bike.
and rim width because it offers more traction...
and bars width because it offers more leverage...
and suspension travel...
You get the point.
Let them try whatever they want and what works will stick out...
Kids bikes started on 24" wheels giving the misunderstanding that 24s are for small people. In the bmx scene 24s are considered big bikes and usually only very tall 6'4" types are riding them. Most pro bmx riders on 20" wheels are over 6 foot at least. The 26" was the original size for hybrid crap bikes and mtb. The 650b was a euro touring wheel size many years before that. My shop has tons of evidence of this in the basement of old crusty 650b tires and rims. The way I see it 26" is a direct evolution of the 20" bmx wheel. Everything I learned racing bmx influences what I do on the trail with the 26". The bigger sized wheels start to loose this feeling and relate more to a 700c road theme. Some people need help elevating over rocks and maintaining speed so let them buy the big wheels.
One of the best things about DH right now is that privateers have a chance at racing in the big events with top sponsored athletes. A few of my friends fall into this category. If wheel size is not regulated at the WC level, privateers will not be able to afford three DH bikes end of story.
In my opinion if you have regulations (in dh) that keep costs down you will eventually have a larger market to sell to which will grow the (dh) sport.
I want DH to be man vs. man. Not like F1 or Moto GP where Money wins most of the time and ability second. Yes it takes a lot of skill to pilot those machines but how many people racing ever get an opportunity to move up to those ranks? .00000000000001% that makes it kinda dull in some way. Keep it simple and the real talented racers will always make it to the top. Price the general public out of the sport and you are left with a bunch of pansy rich kids traveling in pimped out rigs to local races. F$@k that. I want to know I can go race with the best of them. I may never win a pro race but it is a ton of fun racing with them and being competitive.
Still you make a good point. Not everyone can afford to pull a different bike out of the stable depending on the race. I know I can't. Does this mean we should see 29er DH and 26er DH series? It would still allow for innovation I guess. . .
The whole KHS team is on 650Bs now, so... watch the video and tell me that they aren't having fun...
Furthermore: "Fox Racing Shox, has been testing its suspension concurrently with teams that are outfitted with 650B and the report is a time savings of over a half second a mile."
Are you kidding me? all this trouble so pros (which 99.999999939848374583% of us will never even come close to ride as fast) can gain 0.5s over a mile? That's probably 0.00000028381s for us, big deal. I was quite indifferent to the arrival of 650b as I just bought a 26" but the way they marketed 650b it sounded like we'd break the sound barrier with them. I was actually eager to try one but now I must admit that I really couldn't give a shit anymore if the performance gain is that laughable.
@PLC07... if you bothered to read FURTHER, the very next sentences were...
"Intense reports better. Strava times on their very technical home course varied between three and nine seconds better on virtually identical bikes and builds."
And yes, half a second a mile when the difference between first place and fifth place is often as little as 2 seconds, IS significant to professional riders. Three to Nine seconds over the same course, better on a 650B to a 26er, with the same riders, can mean the difference with merely equally the competition or actually crushing them. How would the world cup or US pro gravity tour overall title last year have been different (and the ensuing contract re-negotiations for salaries and sponsorships) if any of the top riders who DIDN'T win events (and the points that come with them), suddenly been 3 seconds faster on their times? This is the thinking of many team managers who have high priced talent under contract now, and a lack of these new bikes to put them on and are likely complaining vocally in the pits to anyone in the media (like Richard Cunningham) who'll listen.
The article was about whether or not 650s should be allowed to race with 26ers... not about which one was more fun to ride. I'm just tired of the constants rants trying to convince people that 650b is more fun than 26". Ride what YOU enjoy and stop with the preaching.
Oh, they can ride whatever they feel faster. If 650b is faster then so be it. If 29" is faster then so be it. I'm not a hater, if in a few years a size sticks out as a better wheel size when the time to change my bike comes, I will probably go with it.
What I don't like is that we're being sold pseudo revolutions before they even benchmarked them... and when the real test numbers come up, the difference looks mostly insignificant for the consumer. It makes them look dishonest at best in a lot of people's eyes. The industry is starting to sound so facetious that I wouldn't be surprised if in a year or two they'll announce they're bringing back penny farthings because the front wheel rolls over obstacles better while you can manual on the smaller back wheel to accelerate faster. I used to read a lot to stay up to speed with the new stuff but to be honest, I hardly ever browse bike related stuff anymore as it's such a joke now... and not a funny one.
without restrictions there will be chaos and anarchy, should we let motorcycles race with bikes as they are the evolution of bicycles?
as for that stupid law of sanctioned races, that is just business management and money hording rule !
Ground effect cars were awesome.
It's a race. Why make it slower? It's not like everyone isn't on the same playing field. If bigger wheels work for a course, you should probably be using them.
twostrokes were banned because manufacturers push 4 stroke engines , do you how many parts are in a 4 stroke motor, i'll tell you more moving parts than a whole 2 stroke engine! = more replaceable parts = more money to manufacturers !
as far as pollution goes , its funny because governments all over are testing nukes and crapping all over the planet yet they asks us to give up what we like!
1 fukushima (or chernobyl )= 1000's of years of 2 stroke pleasure!.
there is nothing like the sound & smell of a 2 stroke ! (sorry if i got carried away this it a touchy subject to me )
LONG LIVE 2 STROKES!!!!!!!!!
650b resemblance?
If you're going to say they should restrict one thing, you had better be prepared to have solid logic behind why one thing should be banned another shouldn't. And so far, I've yet to see anyone do that.
Or you know, let's just stifle innovation and help slow the growth and advancement of our sport all because some kids are afraid of a bigger wheel which is only advantageous in certain conditions. GET YER TIN FOIL HATS BOYS!!
I also can understand the argument about technology taking some of the challenge out of DH racing. I mean if bigger wheels just roll over shit then doesn't that defeat the purpose of the technical tracks? And we'll just have to keep making the tracks harder? But at the same time doesn't suspension technology do the same and no one complains about that.
It would be nice to try and limit technology but that's not going to happen. That's what drives the industry, that's why people by new bikes. I know its a weird comparison but It almost like golf. New technology keeps making longer, straighter, more forgiving clubs. They could limit the technology and they do to some extent, but golf course have changed to adapt. Courses are longer and more challenging to keep pace which is what will happen with DH tracks as the bikes make it easier to ride them.
I personally don't care what wheel size I'm on. The only issue I see is that the bigger race teams can afford to have both 26'' and 650b ready for their riders to pick and choose from. For racers on a budget it's expensive enough to travel with one race bike. I fear that this may lead to giving the "bigger" teams more of an advantage.
as far as the 650B stuff , as long as there are 26" wheels i will use them, if they run out while i still can pedal i will go to the next small size be it 650B or until then 35". but please stop referring to wheel size that predates mtb as an innovation!
don't hate anything (almost) or afraid of progress i'm just content with what i got today!.
Horse shit it isn't. They all can provide MASSIVE benefits over other variations that share the same category as them, you'd have to be baked out of your gourd to think otherwise. To discredit any of those things as being inconsequential is to spit in the face of the innovation of the sport. They all matter and they all make a difference. Do you honestly think the professionals who ride think those things don't matter? If you do I have news for you.... as well as an irritated legion of engineers who spend their lives tweaking everything we ride on ever so slightly because it all matters. Using that logic we'd still be on hardtails using cantilever brakes because allegedly none of that matters.
Don't try to stifle innovation and progression. Accept the changes to our sport with open arms and stop thinking it's you vs them. If something doesn't work it won't survive long. Fads have come and died when they were proven to be useless. If any of this is a fad and is useless, it too will die. If you've been in the sport long enough (for me 20 years now) you've seen changes come and go. Just accept it. The only constant is change.
See pg.10.
@EuanBisset: The reason everyone was shocked is no one believed a 4 stroke could accelerate as fast as a 2 stroke, even with the displacement advantage. The 4 stroke was a 2 stroke killer because of the displacement advantage, which was originally 550cc. Remember no name KTM riders getting holeshots in pro races just because of that incredible engine? (I still have my 2002 KTM 520sx.- don't ride much anymore, but it is a great bike.) ¨They changed the rules to 450cc a couple years later. Please SLOW DOWN and read more carefully. You are jumping to conclusions.
@Cyrix, I did not say those things were not important or did not provide advantages. But I stand by my statement- they are not the same thing as different sized wheels. I also never said we should jump to regulating them just yet, but it may be needed down the road once we find out what effects this has on DH racing as a whole. This is all just discussion, no reason to get wound.
In any event, this debate is all reactionary, as all these kids thought 650b was just marketing. Its pretty obvious it isn't. For some reason people think 650b is a conspiracy. Just about everyone who has ridden one has raved about how good they are. Eating your own shit is hard when you make an ass of yourself.
And let me be clear with you as It looks like you have not actually read my posts, I am not for or against regulating wheel size. I am also not against 650b, 29, 20, or any other wheel.
20" wheels are how much different in size to a 26" wheel? 24 to 26" is much more similar to the difference between 26 and 650b isn't it? They are the same class. This keeps coming back to all the arguments over the past 2 years where all the kids were saying 650b is a disadvantage, and was being promoted as marketing to make money. Now its an "unfair advantage?"
from the above article:
Pre-season tests comparing the mid-size 650B wheels with their conventional 26-inch counterparts has not been promising for those in favor of the latter. Fox Racing Shox, has been testing its suspension concurrently with teams that are outfitted with 650B and the report is a time savings of over a half second a mile. Intense reports better. Strava times on their very technical home course varied between three and nine seconds better on virtually identical bikes and builds. Recently, Pinkbike has done side-by-side testing of 650B and 26-inch DH bikes with comparable results.
Which team would willingly give up that kind of handicap?
If it's really about 2 seconds faster on an average DH course as we've seen it on forums then 26" DH bikes will have disappeared in 2 years anyway.
2) if a larger wheel gives an advantage then they should be restricted to events that are for that wheel size. its not rocket surgery. you can't run a 26" in a 700c race, and vice versa.
3) your bike wont explode because theres a different wheel available, so stop worrying. you dont have to buy it. hell, you probably dont even need it.it is not required of you to purchase every new piece of equipment that comes on to the market In order for you to be a mountain biker. so hush.
So if sombody comes now with a, let's say dorado and 650B and beats all the Fox "normal 26" riders" (I dont't know if thats posssible...^^), what are they supposed to do? Either put a lot of money in development or release an unfinished product. OR of course loose some customers in this segment.
That makes me think that the big Suspension companies like Fox and RS will not support this decision, at least in this point of time.
I think their word weighs pretty heavy everywhere in bike business and you don't want to piss them off...
I guess I', just trying to say that the decision is not so easy as it may look.
Just my 2 cents... oh and of course i voted for "let evolution improve things" ;-)
You are probably right abou fox (though I remember they tested stuff that never made it to production...)
xfusion on the other hand is not really present in the downhill sector and RS hasn't even announced anything about other options...
Anyways,.. I'd love to see manitou more present in the WC. Maybe it's an option for them the get it.
To also keep small teams compatible, maybe it would be an idea to say that teams have to stay with their wheelchoice over the whole season. To have all the spares and materials for both types will probably blow up their budget.
Engaging in an intellectual discussion that has little to do with the key facts of the conversation at hand.
www.urbandictionary.com/define.php?term=intellectual%20masterbation
run what ya brung!
if they dont restrict pedal type then why wheel size?
The wheel size debate is fascinating as it's quite difficult to see where the advantage of running a larger wheel comes from. After running some preliminary numbers the suposed advantage of the bigger wheels on square edge hit of various heights is actually very small, the difference in vertical acceleration as the tyre climbs an obstacle at typical trail speed 20kph is in the milliseconds to the point of being negligible. So if there is reason for the reported increase pace of larger wheels it must be something else. I suspect that its due to the contact patch of the type or greater volume of air in the tyre leading to less contact patch variation. If this is true then it opens the question of 650 with a 2.3 vs a 26" with a 2.7 or 650 with a big volume vs a 29er with a smaller volume and also brings back the discussion on rim width for tyre stability. I think i might write an article...
f*ck off with all the unnecessary sizes of shit. Innovation? Wow, give that genius a Nobel Prize, he thought of, oh holy f*ck!!!! A BIGGER WHEEL DIAMETER FOR A BICYCLE!!! Can you baleedat?!. Genius, just pure f*ckin' genius!! Narrowly beating out the other a*sholes who thought of the brilliant idea to add yet another axle size to the mix, taking a step down in strength, rigidity, durability & saving no weight over the already well established 20mm standard that performed its job perfectly. Congratulations to all, you really are the pinnacle of society, fighting for new standards in all the wrong places in an industry where no one gives a shit about doing it in any of the right places (seat posts anyone?).
The more MTB develops and technologies go in different directions, the more restrictions you will see, and that's good. It will create more sub classes and more race "categories".
Anyways, why would they ban something that anyone can use of free will? Same for wheels or any other gear or component. Plus if they apply this rule, we can say adios to 650b market and any evolution of our sport.
I have no particular opinion on the 26/650/29 debate, it just seems like if they are as amazing as everyone's making out (of which I'm quite skeptical), the advantage can only possibly last a season or two.
Did, in 1995, we limit suspension travel to 3" ?
Is there a limit on how wide or narrow your bars can be?
How about limiting tyres to 2.5" ? Would that be OK.
Can you use both flats or SPD's in DH?
Allow it - its the ultimate test, on some courses it may be faster, on others slower - thats what racing is for - THE ULTIMATE TEST!
If it's better then we know its not just a marketing ploy, if its not, it will be shown up as complete bollocks.
Thats it, stop whining about it, and UCI - get a F**king grip.
The way that the pro riders win or lose on 26, 27.5 or 29 in all disciplines including DH is the way that us amateurs can decide between them! Removing other wheel sizes from racing dumbs down the sport and confuses the consumer and the whole industry. If Sam Hill or Arron Gwin are quicker on all or certain courses on another wheel size, I want to know which ones, most likely it doesn't actually matter that much, but lets see, more bums on seats at least?
There is no safety issue with 650B wheels in comparison to 26". Let's face it , a top rider pushing his/hers limit will have the same danger of hurting themselves no matter the wheelsize.
As for equality, there is no real price difference between the two sizes. A rider from a developing nation will be able to get the same bike for the same price. If you look at road racing, this plays a bigger difference where a rider from Italy can get much lighter wheels and components than a rider from a developing nation that does not have the same resources to benefit their athletes.
The UCI certainly isn't rational so who knows what they'll do?
Correction - for what its worth the difference between 26in and 650B is actually only 25mm (bsd of 559mm - 584mm = 25mm)
--------------------------------------------------------------------------------------------------------------------------------------------------------------
If 650b wheels have advantages, why have mountain bikes traditionally used 26in?
Regular mountain bike wheel size arrived at 26in as much by accident as by design. Many of the old steel-wheeled clunkers that gave birth to the original mountain bikes had 26in wheels, so early aluminium rims were simply made to replace them, although the long wheelbases and big tyre clearances of frames back then could easily have accommodated bigger wheels and tyres.
650b rims and tyres were readily available, as were the old 27in road rims, which effectively standardised into the 700c road rims of today. It’s those 700c road rims that have had their rim beds widened to take fatter 29er mountain bike tyres. By the time the early mountain bike bandwagon got properly rolling, 26in rims and tyre choices were becoming more plentiful than 650b or 27in. Inevitably most frames were being designed around 26in wheels too, so the habit stuck.
Well, it stuck among most of the mainstream builders. A few custom builders were still meddling with big wheels on mountain bikes and it wasn’t long before Gary Fisher got people talking again by launching a range of 29ers. A few others followed and within a year or two the fork, rim and tyre manufacturers started creating more choices for the slowly growing base of big wheel fans.
Now that 29ers have earned a place in the mainstream, 650b has returned to the spotlight. It makes sense that wheels measuring half way between the established 26in and 29in standards should be considered.
also good job PB for lighting up a flamewar, this is good stuff
^^Yes.... and I'm ok with that.
Flame away, i dont care i ride a mtn bike, not a cc, trail, all mtn, freeride, dh, slopestyle, dj, cyclo cross, fat bike, etc.....
Nothing should be banned unless it is blatant cheating (doping, engines etc). Technological advancements are not cheating.
I say let the racer make the choice on race day as to what equipment he should use to obtain the best results.
By that logic, a 29 x 6" fat bike will be top.
12 inches of travel?
32'' wheels?
Why stop at 650b? Its not some huge technological advancement, it's just common sense- bigger wheels will roll over the rough stuff easier. Equivalent to taking out your V6 and dropping in a V8, then being in awe of the "progress" you've made.
In real life this does not matter. None are "pro" except maybe 50 people around the world. You ride fast, stop, chat, ride. Fun is the word, seconds dont matter at all.
What are the drawbacks? Heavier tires, heavier and weaker rims, heavier and larger frames, funny looks, less flickable, another standard made to increase cost.
Its a dumb marketing move and not an sound engineering decision.
Stop Richard Cunningham. He is an industry shill promoting what he is told to promote. This guy should write for an industry rag like MBA.
I say - 26 is better riding, longerlasting, cheaper and looks better.
XC/Enduro and Dh/DJ are two different sports. Bringing them together is pointless and failed many, many times.
If I do XC/Enduro, I grab my old and low 26` 1992 Pinemountain hardtail with cheap Duro fork and Maxxis Detonator slicks. Climbs and descends better than fancy and expensive XC/Enduro bikes from today. And
Weak sh*t.
Restricting clothing and wheel sizes is stupid...
I think that if 650b are that much faster we'll be seeing alot of DH bikes for 2014 with them as OEM.
OMG... haha... That is all.
Typical RC article.
a) 650b is a technological improvement
b) the UCI (like other sports federations) banned these before.
RC then poses the question whether they should do it in this case - all speculative indeed.
: no skin suits in dh. so should 650b's be restricted? maybe, maybe not, but some limit has to be laid down obviously.
Either they're all on 26" or they're all on 650b, it doesnt matter which.
If one has a clear advantage over the other (as seems to be the case based on various recent tests) then the fine balance between man and machine starts to swing in favour of machine, which has to be contrary to what the UCI is trying to acheive, like us, they want the best rider to win races, not the best bike.
If there are further advancements to me made in DH bikes (and there certainly are), then at this level, its up to the manufacturers to find those advancements within the rules.
This system works well for just about any other sport you care to mention, motorsport included. Without them it would be a complete technology free for all where riders were seen as a less important component than the bike they're riding.
