Broken Chain Ring Bolt

[northshore]

I was cleaning up, repairing, my SS and noticed one of the chain ring bolts was spinning. Barely touched it with my finger and look what plopped on the floor. #-oThese are just plain old alloy BMX bolts. Do I hammer that hard or maybe I'm just plain chubby on the bike. Time for stronger ones!

You're just too much of an animal for standard chainring bolts! It may have partially failed from tightening. I've never seen that before.

I'm with 2wheel on this one, I have seen that from torquing them down too much.

On my first single speed I used a set of Truvativ Stylo cranks. The chainring bolts would not stay tight and I would weaken them by over tighening them and they would break. Used Race Face steel bolts, worked better but still creaked. From then on only use spiderless cranks on a single speed.

Ive broken the chain ring bolts on my race face deus crank. I was just tightening it and the head just sheared off. Ive replaced them with generic steel ones and they have been just fine. Its a couple grams heavier though. #-o

Definitely go with steel bolts. Sugino makes a good set.

I saw this happen to some guy while on a ride...........but he broke 3 of them on his granny so we zip-tied it (so as not to take the cranks off) and he finished his ride on his middle and big rings.
