Replacing 50T chainring

[livpoksoc]

You can use threadlock, but I tend to use a bit of grease instead, if tightened properly they won't come undone, and the grease will help when it comes to undo them again.

Ceramic grease is probably fine, I use Shimano assembly grease for things around the bottom bracket.

Thanks. I used some lithium grease as it was nearer to hand than the tub of ceramic.

Next up the fun came when I found my torque wrench only went up to 24nm. I have a bigger 1/2" drive torque wrench for doing cassettes, but I don't have a 1/2" 8mm bit. Sets look pricey, so guess I'm without the bike until I can get hold of the right bit and/or a reducer set? Does anyone know if the reducers have any impact on the torque going through the wrench? I.e. does it impact accuracy?

Never used a torque wrench on chainring bolts - I just tighten them up good and tight - the grease helps here. Then I check them after a couple of rides - not needed to do anything with them yet.
