The International Cycling Union (UCI) has approved disc brakes for competition in the 2010-’11 cyclo-cross race season. The ban was lifted via a newly issued document entitled, ‘Rule Amendments for Title 1,’ which was posted to USA Cycling’s website late Friday morning.

Following the recommendation of the Cyclo-cross Commission, the UCI Management Committee has approved modifications to its cyclo-cross rules which will take effect at the beginning of the 2010-2011 cyclo-cross season. A summary of the changes is as follows:
1) Disc brakes will now be allowed in cyclo-cross competition.
2) The legal tire width in competition has also been changed. Width shall not exceed 33 mm, whereas before the maximum width was 35 mm.
4) The “6 obstacle limit” has been changed to a “6 man-made obstacle limit.”
5) The height of barriers is now a maximum of 40 cm instead of a defined height of 40 cm.
6) Man-made sand pits are now allowed and the dimensions for them have been established.
7) The distance between planks has been changed to a range of 4 to 6 meters between.
8) Commissaires may now authorize feeding if the temperature is above 20 degrees C. This feeding takes place in the pit lane, but not during the first two or the last two laps.
9) The commissaires may now invoke the “80% rule” and remove a rider who is behind the leader by 80% of the leader’s lap time. Thus, riders can be pulled before they are lapped.

... The same document also newly restricts tires used in UCI regulated competition to 33mm at their widest part and reiterates the ban on spikes and studs....
... The basis for the rule change is to make the sport more approachable, equipment wise, to juniors. Thorne explained, in Belgium the top juniors believed they needed to mirror the iconic rider’s equipment quiver to be competitive, subsequently building a huge barrier to entry, especially on a developmental level....
Thorne believes that whatever the tyre width regulation does to ease the financial burden on privateers will totally be undone by lifting the ban on disc brakes, at least in the short term.
“I can tell you right now, it’s going to be more costly,” he said. “A set of [TRP] EuroX’s will cost you $100… the cost thing goes right out the window with that one.”
Aside from the added cost when comparing the price of a disc brake to a cantilever brake, the change will likely double the number of bikes in the stables of the sport’s highest profile teams and riders.
... An unconfirmed report pins Shimano and LaPierre bicycles as responsible for the change. The two manufacturers reportedly approached the UCI four or five months ago with a disc equipped cyclo-cross bike and a proposal for the rule change...
