Stem is a one piece stem / steerer for Lefty. 100mm x 5deg. 31.8 clamp. $20 incl USPS shipping.
Hub is a Lefty Si 32h. $20 incl shipping.
The hub is currently built into a 26" wheel with a ZTR Race rim. I'd send the whole wheel if the buyer was interested in that, but I would have to charge shipping for that. $20 for hub $20 shipping = $40 for wheel shipped.
