  • Not sure if this is the correct place to ask this but it's a bit of a bodge in my eyes.
    I just got a new 105 5800 chainring, where the bolts screw directly into the chainring itself. Somehow, I've managed to use 3 normal length chainring bolts and one shorter single ring bolt, the single ring bolt pulled the threads out as I tightened it.
    Instead of throwing a brand new chainring in the bin, I think I may get away with using a longer chainring bolt as there's still a bit of thread left in there and there seems to be a bit of extra depth there too.
    Question is, where can I get longer chainring bolts? Or any m8 bolt with the correct pitch?
    Or, am I wasting my time and admit to myself I just ruined a perfectly good, brand new bike part.......again

  • I knackered the threads also on a 5800 and fixed it the same way. The threads on it were way way way deeper than the factory bolts need, so should be fine.
