WTB i29 disc wheelset. 27.5" / 650b size. Tubeless ready, but never set up tubeless--so they're not all gooped up with sealant. Includes skewers and 160mm disc rotors. Taken off a lightly used Surly Bridge Club. The frame has a 138mm rear spacing (which Surly calls "Gnot-Boost"). And the OLD of this rear hub is 141mm.
