About 10,000 miles on my touring bike, not all but the majority were touring.
- Tires - about 1.5k rear 3k front (my lighter and lighter loaded companions did much better)
- Brake pads - 3k
- Bar tape - 3k
- Spokes (rear) - some breakage at random intervals
- Chain - I replaced it at about 9k, but it was still within normal tolerances. I figured that it was probably due at 10k and I didn't want to mess with it on tour
- Bottom bracket - still ok
- Chain rings, rear derailleur, rims, saddle - all still OK
