Disc brakes are banned from CX under UCI rules, right?

So who makes this disc brake mount?

It looks like a tubular-shaped fork leg with a metal band clamped around it, on which is mounted the avid mech. disc brake:

It's a WoundUp fork. The disk brake mounts were machined as part of the dropout.
Can't use disks in UCI elite men, women and junior races, as far as I know; when I did the Pilarcitos race in the Bay area, it was UCI race for previously mentioned categories but in Masters, they didn't stop anyone from not using them.

USCF is phasing in the UCI rules, so the ban on disc brakes will apply to all US racing within a couple years.
(i think it's by 2007- we are coming up on the 2006 UCI season this fall, so maybe that means in about 1 year for 'cross)

something to consider depending on what you use your bikes for and how often you plan to buy new ones.

My question is, why? Why are disks so evil? (you pay a weight penalty isnt that enough?)

I don't cyclocross, but this is one thing I hate about UCI/UCF/whatever...their rampant "no this, no that." I guess it's their anti-recumbent policy that is the most annoying (just cause back in the 30s, a 'bent rider stomped all the pros), but it stifles progress. I mean, it's like saying, "in all car races, you can only run 4-cyl engines with single carburator setups."

How will a general ban on disc brakes affect the market?
Will this stop the development and production of new models, and availability of spare parts for existing ones?

Why would disc brakes be banned in the first place?

I've heard it's a safety issue, but I don't know if that's the only or main reason.

that in racing in packs (such as road or 'cross, but not really mtn so much) there is a danger of falling on somebody's disc and being cut by it (or burned?) - something like that.

you can still race on mtn bikes with discs, and you can use them for recreational road and off-road riding. so no reason to think it will affect the market for spare parts and development. the CX market is tiny compared to the mtn bike market, so it wouldn't affect it much anyway.

I have done races with guys who were running disks and still haven't heard anyone getting cut a disk...now, getting slammed into a tree or a barrier, that's a different story. If I remember right, the bike mfr's have to submit their designs to UCI for approval in any of the races that UCI runs. But, the mfr's didn't so UCI immediately banned them. I suspect that some Euros on the UCI tech board had a problem with disks on a cross bike.

Most races have rules and to make rules boundaries need to be set with clarity. Even auto racing has specific and often intricate rules limiting engine size and minimum vehicle weight.

As to why disc brakes are banned, I can only speculate, but CX racing has a history and tradition of being on less than ideal course terrain, often with mud and snow. Disc brakes would provide a certain advantage in these conditions and take away some of the tradition and sport of dealing with mud build up, blocked brakes, washing down bikes during a race, etc.

and ti/carbon bikes are taking away the fun of climbing a steep hill with a heavy bike. and dont forget all these damn gears theyre slapping on bikes nowadays...please. i just recently decided to try cx and am a bit disgusted with this.
ah well. no racing, then. im definetly using discs :]

You'd think the saw blade shaped chainring would be more of a danger...

slvoid

I'm guessing its the same reason why auto racing has limits on electronic driving aids and motor sizes, to try to stay true to their roots, even if for a little bit.
