lancearmstrong: UCI approves disk brakes for cyclo-cross. Great news. I look fwd to the day they're approved for road racing.
De UCI heeft vanaf het seizoen 2010 schijfremmen toegestaan in de cyclocross.
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'
Maar de UCI gaat verder ook de band breedte meer beperkt is: 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.
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.
3) Continental Cyclocross Championships have been established.
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.
