chainring bolts?
I have noticed that after a little while my chainring bolts seem to get loose. Its happened with both bikes that I have had.
Is this something normal that just happens with fixies? or is there something I should do to stop it?
Thank you

I assume somebody will say Loctite, since it seems to be the fix for everything here.

Your cog is slipping.
It happens to all bikes.
Clean all the grease off your bolts, apply a drop of blue Loctite, let dry and reinstall the bolts. It obviously won't hurt to check them periodically but you shouldn't have to mess with them very much.

I grease mine. No loctite.
FWIW, I prefer steel bolts. I also like the ones that have allen heads on both sides.
You gotta torque them more.

I always used grease too but they kept getting loose. Sugino knurled bolts + Loctite FTW.
And yeah, stay away from alloy chainring bolts.

What would be the difference in tightening the knurled bolts? Still appears you need the chainring bolt tool + allen key. Never used them, so curious is all.

You don't need to use a spanner at all because the knurled outer edge prevents the rear bolt from spinning. You can just hold it with your fingertip until they start to grab.

I've had nothing but luck with grease and torquing them down good. I'm pretty firm on this not being a loctite job, but I guess if it works for you do your thing. Those knurled bolts look awesome, by the way.

Get some quality steel bolts, use grease and lock them down tight or use blue thread locker.

I used to grease + torque as well, now I blue loctite, I check them periodically and they generally don't move at all.
I still use a chainring bolt spanner too, but I don't mind taking a little time with it.

In my experience the chainring bolts on my fixed gears always loosen up. I guess it is the push and pull of the chain from frequently track standing. Chainring bolts have never been an issue on my freewheeling bikes.

Agree. I have no evidence to back it up, but the "wiggle" effect of applying backpressure may loosen the bolts due to friction.

ordered some knurled bolts after I came home to 2 missing from my chainring last week. labor day weekend = not checking up on **** I should've been. no idea how they came completely out, guessing they came loose and I just kept on riding, ignoring that weird feeling from my drivetrain because of alcohol

on my singlespeed/fixed bikes i always have to retighten new bolts 1x after installing a new chainring or bolts.
i will install, ride for a day or two, retighten, and forget it. dunno why they like to come loose once but they do for me.
if you remember this clip you are probably to old to hang out here:
