It depends.... what do you have?

I've got a motley collection of "stuff"
105 areo brake levers.
Shimano 7-speed bar cons
Various derailleurs including a couple of bottom pull XTR's new in the box.
Welgo pedal and toe clip/strap set new in the box
Lots of other assorted small stuff.
I might even be willing to trade for a back up wheelset hand built by me. New Tiagra 9-speed hubs, CXP 21 rims, DT competition spokes, 32 hole 3X.
