New cog

When putting on a new cog, what do you guys/girls use - grease or anti-sieze? Also, do you really need a lockring and chain whip tool? I don't like the look of the rotafix method, I like my paintwork!

Any other tips for putting on a cog? I've never done it before.

Just use a thick rag or something to look after the paintwork

^ with the rotafix method.

i've always just used a chainwhip and rode up a small hill to tighten completely, then adjust chain again. lockring i put on with a hammer and flathead screwdriver (tapping lightly). be sure to use grease on the threads.

I wouldn't use normal grease (just because my cogs seem to always `fuse' to my hub and require a lot of effort to remove with standard bike grease). I now try and use a high torque grease such as copper grease.

To install cog + lockring:
Clean the threads off your hub and cog, lightly grease and spin on the cog till snug with your hand. Once its firmly on, then use the rotafix technique or a chain whip to get it snug. You can 'ride' the bike to snug it down but be careful, and apply the pressure smoothly.

Do the same with the lockring (using hand first then tools). The lockring should be counter-threaded so it spins on and tightens the opposite direction to the cog.

Once you've got the lockring snug, ride the bike around a bit (trying not to apply any back pressure) and then snug the lockring some more to be absolute safe.
