obviously !....but the difference in a set up can make a massive difference for 2 riders on the same bike...
I think you need to contrast the performance of spies and lorenzo...supposedly on the same bike, yet one comes 2 nd the other comes 10th...if the set up dont suit the rider then he cant perform. Spies has shown he can race, either he or the bike are not in the zone .Yet after just 2 races this season there is already talk of him being replaced by Crutchlow ! Feck, its a competitive world...
