I have a RaceFace Diabolus Crank set and when i was changing my chainring yesterday realized that i broke off one of the 4 arms of the non-replacable spyder anyone ever say the heck with it and bolt on everything with only 3 bolts holding the works together? I installed the 4th bolt with the broken piece... its strong to my hands, however i dont know what i will do when i whack a rock.
