Have: Shimano M089 MTB shoes in a 44 Wide (2 bolt)
Looking: 45 wide version (The 44 is a bit too short for me).
Have: Continental Valve Extender 20mm (this is the version for removable cores)
Looking for: 60mm version
Have: Rotor QXL 36t 110BCD ring (5 bolt) (has less than a couple hundred miles, teeth show virtually no wear)
Looking for: Rotor QXL 38t 110BCD (also 5 bolt) or a Q-Ring in a 38t or 39t would be considered too in good condition.
