Disc brakes banned from UCI cyclocross races(17 posts)

Disc brakes banned from UCI cyclocross racesAJS

See the write-up at [url][/url]

Whatda you guys think of this? Shouldn't a rider be able to use the kind of brakes he wants, as long as everyone else has the chance to do the same? And how does using disc brakes impair a CX race? I would think they would be a positive thing for CX'ing, considering the mud, etc.
And that is a good thing! (nm)phatlizard

I've done races where no single canti was able to slow me down on the steep descends, jsut before a sharp slippery corner by a big tree. Scary. I'd love to use discs, and my competitors to do so too.

Bet that it's got something to do with 29" becoming legal for mtb'ing, and CX trying to piss off mtbr'ers that want to join CX races on their only bike, which happens to have discs (and for a reason). Take a 29" bike, shorten the bars to 500mm, and get some skinny tires, voila CX bike!
Not sure, if my guess is correct, that it's a smart moove to oulaw any MTB technology. Better outlaw carbon and tubulars, that's what makes the sport hard to access, and keeps the starting fields as small as they are. (Dutch Elite champs : under 30 participants on avarage, while it's an open race). To be competitive in CX, you need LOTS of $$$ carbon wheels and custom made tubulars.
Since when is it bad to have more participants and some pregress in bike technology?
Didn't think of it that wayAJS

I've always thought CX events were small mostly because it's harder to control a road-type frame & relatively skinny tires off road, and because a lot of guys just don't wanna ride at this time of year (rain/cold/muck)? I think CX just seems too "ballsy" for many of these wimp-assed MT bikers! ;^o

But you're saying it's the need for high-end equipment that's keeping the average biker away? I can imagine someone with nice CF rims pressing the pads into that brake track, grinding them down with dirt & mud more by the minute. Seems like UCI would have lots of complaints to allow discs just for that reason alone - that CX is too hard on equipment, therefore most people can't afford it.(?) Not to mention scary!

When I bought my current CX bike (a demo K2 Enemy) the dealer already had discs mounted on it. He wanted to give me a really great deal on them, but I was lucky to afford the bike at all, and had to turn him down on the disc brake option. No prob - he put the OEM canti's back on it.

Bummer, cuz discs would be THE thing to have on a Mud-bomber!

I've been told this rule will only apply to UCI sanctioned events, and then only in the "A" class or higher. Someone earlier stated that it was a safety issue, why or how I don't know. Maybe next they'll have you ground down the teeth on your chainrings...

I'm told USCF won't be following this rule. I'll race next season in the beginner or C class, and have been looking at a Cannondale disc, I figure I'll still buy it.

Shouldering and running bike could cut you or someone else in a really bad way. I understand the ban.
Don't you think there are a lot more dangerous parts of a bike?skateparks

Pedals, brake levers, skewers, cogs/rings, etc, etc, etc?

Considering some of the dangerous PEOPLE that I had to race against this weekend, I think rotors are the least of our worries...

Rotors can get EXTREMELY hot to the touch...KonaMan

From my DH experience, they are sharp edged and very hot, makes for a bad combination if you ask me. Besides, it's more fun carreening out of control with very little brake on skinny tires!
I'm not buying it.TWD

Sure careening out of control can be fun, but I don't think this ban has anything to do with safety issues.

The Avid mechanical discs are the only ones that I have seen used for CX and are the only ones that are compatible with road levers that I am aware of.

I run the Avids on my MTB and they do not have sharp edges so the term "butter knife" would be far more applicable than "Razor Sharp".

As for the heat factor, sure they can get hot, I've got a burn scar on my calf from the rotor, but that was after a steep/continuous 3000' descent. They won't get that hot for CX. The downhills are way too short to generate much heat. If you are using your brakes so much that they get that hot, you wouldn't have to worry about burning anyone, since you'll be racing by yourself.

I'm waiting for the UCI to come up with some real justification other than "safety" cause that just doesn't cut it. All of the "what if" scenarios that one could generate are far outweighed by the safety gains that you would get by having brakes that actually work in the muck.

That is the dumbest thing I have ever heard. You must work for the UCI.
Second that! Where do you get sharp rotors?...TFerguson

My Hope minis are about, no make that less, sharp than the back of a butter knife.

And as far as "red hot"... On a CX bike?

Besides, even if all that were true, I have a scar on my right calf where my chainring took out enough meat that I stuck the end of a garden hose in it to clean it out. I still use a chainring because they work.

This is the link from USA Cycling that talked about disk brakes:
This ruling only applies to UCI events and only if you intend to race elite men, elite women, U23 or juniors. For masters, B's or categories not under this ruling, can use disc brakes. Although I would think that masters world's might not allow disc brakes either.

Plus, are disc brake rotors that dangerous? Round pieces of metal? And chainring teeth are safe for all?

Let's get chainring guides, foam bumpers for the end of the drop bars, bubblewrap for the hard, streamlined saddles and rubberized pads for pedals as you may bang your shin.

Oh, I almost forgot, let's have the races on pristine courses and each person goes one at a time since we wouldn't want any contact or potential falls so no mud or steep drops or singletrack...

You guys and gals get the picture... Oh wait, may be I should have warm fuzzy bunnies around this email to just to be safe.
"Safety" issue sounds like excuse to meAJS

Like you've all said, there are other parts on a bike that are as potentially harmful as disc rotors.

Seems to me that one assumes the risk when one enters any kind of race - bicycle or otherwise.

Yep. I have a big long scar on the shin from someone's chainring when I did a road race a long time ago. So, getting cut by a disc is the least of my worries. Tree branches, fence posts, lava stones, etc. DO worry me!
The only problem that I can see with disc brakes is swapping out the wheels quickly if you get a flat but that's just guess since I don't run discs.

Got a contractor's staple stuck in my arm from a 24 hour MTB race, but I don't see the UCI banning staples for posters, signs, etc...
Best explanation I've heard...TFerguson

UCI is protecting the Euro bike builders who do not have the disc technology of the non-Euro (North Am and Asian) builders.
