Do all 104 BCD chain rings fit?
I am helping out a friend who wants to spend as little as possible to get his bike sorted. I have finally worked out that his gear slip problems are down to a bent middle ring on a Truvativ square taper chainset. I did this by process of elimination swapping various bits from my own bikes. I understand that the Truvativ has a 104BCD but all the Truvativ 32t middle rings I can find are 24 quid plus. I can find a Shimano Deore ring with the same BCD for half that. Will it fit?
