Set of non-boost MTB thru axle hubs: front spacing is 100 x 15mm and rear is 142 x12mm. 32 spoke holes each, six bolt disc attachment and the free hub body is Shimano 8/9/10 hyperglide. Rear hub is not as smooth as the front but the freehub body spins freely. If you opt for local pickup I can deliver anywhere in the greater Tucson area for just $20.
