SRAM Roam 40 Boost 29er wheelset with SRAM XD driver. Rear wheel (148mm spacing) is brand new, never even had a brake rotor or cassette installed and never installed on a bike. Front wheel (110mm spacing) is used and has had the decals removed but has just been serviced with brand new bearings and functions as good as new. I would prefer to sell as a set, but will consider sale of the individual wheels.
