RS7 & RS8 cranks
The RS7 and RS8 crank sets have been tried and tested by thousands of riders since 1998.
The RS7 cranks have been used all over the world for all different disciplines including world cup downhill, touring, cross country and trials.
The RS8 cranks have been ridden to victory in the world cross country championships and many national and international events.
