If you don't you'll just rapidly wear the rear cog to the same state as the chain.
rgds, sreten.
that I do know. thanks all the same though. it's a pretty knew chain so it should be all good. i had just bought a new chain and bottom bracket and after installing them at my homies place i was rummaging through his parts bin and found the cog. I was already planning on pickin up a 15 so i figured as long as it wont be an issue i might as well save myself a lil loot.
anyway thanks all. cheers.
