Simply, the chain ring bolts on my fixed gear loosen up often enough. I have a chainring bolt tool and I try to torque them down but sometimes weeks, sometimes months, later I find them loose. I'm lucky I havent lost any in the middle of a ride. This has never happened on my road bike, I torqued them once and that was it. What is going on here? This is happening on two different crank sets by the way.

I am guessing it has to do with the push and pull of the chain. I always trackstand but I hardly use my legs to slow down. time for some loctite

While on the topic; Origin 8 chain ring bolts suck. They break so freaking easily
