neotropolis Posted October 7, 2008 Report Share Posted October 7, 2008 I have now gone through 2 chainrings in the space of three weeks. The bolts that hold them onto the crank just dont seem to be strong enough. Any suggestions? Quote Link to comment Share on other sites More sharing options...

gzus11 Posted October 8, 2008 Report Share Posted October 8, 2008 (edited) i cannot find my first thread from building my bike, but this happened to me alsowhat i did was replace them with propper bolts, i think they are M8 dome headed bolts.i broke these, sheared the bolt, cracked nuts and stripped threads.
