Stuff I ordered and got the wrong thing or customers changed their minds about:
-XX1 175mm cranks. No ring, no BB. Installed but never ridden - dude needed 170s, doh. $200. Happy to add in a chainring if you need one as well for a few more bucks.
-Red King I7 headset (fits 44mm head tube, for tapered steerer fork). Brand new. $120 or $100 for current frame owners/waitlisters/new orders.
