I've looked over all three bikes I used at the Addison race and have to replace a number of items, although not as much as I had feared. I may discover more though as time goes on.
The list for now:
Scalpel headset bearings
Right side XO shifter ( the one on there is first generation and still works but heading south)
Derailleur hanger - I had a spare but ordered a few more
XO Derailleur B screw - it broke off when the hanger bent
Scalpel shock mounting bolt - unfortunately this is the Scalpel's weak point, it's broken before
XTR derailleur pulleys - the HT was running 1x8
I changed cables on the Scalpel but everything else on the bikes seems OK and within specs, just a little more worn.
