Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Is it just spinning in place?
Because that doesnt mean it's stripped, that just happens when you dont secure the back when tightening.

I've never stripped a chainring bolt per se, but I'm sure it can be done - I seem to have stripped every other goddamn bolt on a bike at one time or another. It stinks being so stupi-- er, I mean strong.

Never stripped a chainring bolt. I think it would round out before I could strip the threads.

and yes if it is spinning and you cannot get enough grip on the back you will have to drill that ish out.

I have only had problems with the cheap bmx chainring bolts-like rounding them off where the allen wrench goes or even tightening them down so much that the female part breaks in half or cracks. Once I switched to steel, I have not had anymore of these problems.

Slightly similar problem, mine seem to have rusted in a slightly loose state. It's annoying and is responsible for a creak. I'm assuming I'll have to drill them out. I don't really want to do that though. Any other ideas? Or is that my only bet?

Penetrating oil, trying over and over and over again, and eventually settling for the drill if needed. I thought all 5 of mine were stuck but only ended up drilling 3 of them.
