Hey All,
 I have a Trek 2100, with Shimano STI 105's as the gear/component package.
 It's from 1994, and is approaching over 4,000 miles.  Other then
 greasing/degreasing the chain and gears, I have done nothing with the
 bearings, hub, etc.
 How often should the crankshaft bearings be replaced? Am I need of a new
 chain? Do the sprockets on the rear wheel need to be replaced?  What other
 maint should be done to keep the bike in tip-top shape?
 I already have it planned for the shop to do an adjustment to the gears and
 brakes and am wondering what else they should do at the same time..
 Thanks!
