Pro road racing bikes are heavily regulated. The question to VeloNews is why. Interesting response, but what caught our eye was a caveat in UCI regulatory language regarding mountain bikes:
Except in mountain bike racing, no technical innovation regarding anything used, worn or carried by any rider or license holder during a competition (bicycles, equipment mounted on them, accessories, helmets, clothing, means of communication, etc.) may be used until approved by the UCI executive bureau.
So mountain biking gets a pass?
“We suspect extreme designs may not pass muster,” VeloNews observes. We suspect it’s a moot point. The relationship between speed on a mountain bike course and bike design is far more subordinate to non-design factors, including rider skill, terrain and weather conditions, than with a road bike — which is as it should be. We would like an example of an “extreme design” that would actually aid a downhiller or even XCer (beyond today’s designs). The one biggie — suspension travel — has been pretty much maxed out within the laws of physics. You don’t necessarily gain speed through more travel or greater aerodynamics or even light weight: The thresholds of over-design (e.g. stupid light) have already been tried to failure point. And that’s why the UCI hasn’t really come up with anything in the way of regulation. They haven’t needed to. But you never know. Someone could figure out a way to fill a frame with helium maybe. Or devise an anti-gravitational bottom bracket. Or tires that have wings.
The other factor here, alas: The money at stake in mountain biking competition is so puny compared to the road scene. That’s why the best mtb racers have been going over to road. It also might help explain why the UCI hasn’t been particularly motivated to get into mtb oversight.
Lack of regulation on Mountain bikes has also been part of the culture and a desire by the manufacturers to sell more bikes. Who would buy a new Mt. bike if the difference was only a couple of ounces on the frame? Whereas I have a mid generation full suspension bike which is fine for downhill cruising but it pogo’s badly when climbing. If I rode more, I’d be trading it in for one of the newer designs that fixed this.
The other group with no regulation is the recumbent cycles. We are all awaiting a material to be developed that would give us a fully enclosed bike that doesn’t weigh in at 80lbs. Thus giving us a truly all weather commuter bike that is fast.
i ride a pronghorn racing mountain bike,i am 63 years young,i ride in snow,ice ,mud,beach,sand,i know there is a surly pugsley than can go under water,or do what i do ,since the tires are larger than any mt bike tires. to increase sales in mt bike industry,first talk to customers,using simple terms,not bike lingo,explain, to them this can be an exhirating experience,once you can master it away from cars,smog,and using technical skills you thought you did not have,our company alternative health and transportation company does just that thanks again barton cohen
currently the pronghorn is still being distributed overseas,i do not know of a usa distributor at this point oct 2011,unless i am wrong if you interested,you should contact the companies website,www.pronghorn racing.com,we are located in new jersey and have the knowledge,skills,and athletic abilitly to ride this what we refer to as not a bike but our mona lisa,it is a artistic,and innovative design we feel unlike any mountain in world,if you have someone who can instruct you,before you buy,you will definately think twice about going to the health club,gym,or running marathons,or just running around a park,weather will note not be a problem for the pronghorn we know from vast experience,we also tested two dutch made cargo utility bikes, 55 lbs each,it should be used on the street,but we have used in certain places on a dirt trail for a limited time,but it should be noted that it can be dangerous if you are not trained by an experienced instructor,thanks barton cohen our company alternative health and transportation company is located in williamstown nj
2011 dec 28 update,from what i know about pronghorn i understand that they are still distributing overseas,but you can purchase one direct,according to the site,this moutain bike is so innovative that if used properly with quality snow tires,it can be used all winter,when most riders, leave mt bikes in garage,and go to gyms or health clubs,they can be missing the greated rides of their lives, by using the pronghorn or any other good quality mt bike with snow tires,or the surly pugsley,if you want further information form us let us know through our email address thanks barton cohen 609-816-0935
