[Closed] so I sheared a chainring bolt

Well I bought a second-hand m761 chainset and took it apart for a good clean. Was bolting the granny back on and over-torqued a bolt which sheared (rats...) so do I shrug and think 3'll hold it OK or try to fix the situation and if the latter - how?

Ta,

Infidel the idiot....

Definitely try to fix it. You may well find that trying to get away with only three bolts will put them under more pressure than was intended by the manufacturer and that they will shear off as well. I had the same problem with an FSA chainset except I didn't realise it had happened until the chainring had twisted itself around the remaining three bolts. The inner ring was ruined along with two of the bolts that were still attached.

There are four bolts there for a reason.

Fine with 3 short term but get a 4th so you dont bend it.
