I just finished completely stripping my $2500 (at least thats what I try to convince my wife it cost) touring bike down to the last bolt and rebuilding it. I lubed and cleaned the hubs, disassembled and cleaned avid bb7s, seperated the chain and installed a quick link, removed and cleaned the cassette, cleaned (basically looked at) the bottom bracket and headset. I am not afraid of it anymore. It cost me less then $50 for tools (all park, don't buy crappy tools) and parts. NIKE said it best "DO IT"
