The UCI will allow disc brakes on in cyclo-cross races effective at the beginning of the 2010-2011 'cross season. The organization's management committee approved the change upon the recommendation of its Cyclo-cross Commission.
At the same time, other changes to 'cross rules were approved. The maximum tire width has been reduced from 35mm to 33mm.
The six-obstacle limit on courses has been changed to refer to man-made obstacles. The plank-type obstacles can be up to 40cm tall instead of having to be 40cm tall, and they must be four to six meters apart.
Man-made sand pits are also now allowed and feeding will also be permitted if temperatures exceed 20 degrees Celsius; however, the feeding is limited to pits and can happen only after the first two laps but before the last two laps.
Similarly to mountain biking, commissaires may now invoke the "80 percent rule" and remove a rider who is behind the leader by 80 percent of the leader's lap time. Thus, riders can be pulled before they are lapped.
