Today I overhauled my drive train. The axle nuts/locknuts on my Novatec hub somehow came undone and now the bearings are a bit rough. New 20t ALL City cog, KMC chain, and Shimano cartridge BB. I bought a gold k710 SL but it did not have enough links ok, so I took a link from the previous K710 to make up and now all is well, but still :-/
