hey there guys i was just admiring Ali C's czar bike pictures and i also read a thread cant remember what one it was, that he uses hollowtech cranks, can you tell me abit about how to make them trialsable?, also do you know what is the difference between hollowtech 1 and 2? i have been looking on CRC and they only seem to do hollowtech 2, please help or do you recommend anything different than the hollowtech i really want something light, pretty strong thats why i kinda want to go to hollowtech, but dont know enough about them, i heard i will have to do some machining but that will be ok cheers thanks for your time tom
