The Mavic Crossride Mountain Wheelset has been upgraded once again to bring you the best across the lines of sizes 26er, 27.5, and 29er!

The wheel is has a disc specific profile outfitted with an alloy monobloc axle to be compatible with Sram XD and Shimano 11 speed hubs. This makes the capability both 9/12x135/142. Mavics QRM sealed cartridge bearings are extremely high quality with low play, tight tolerances, and high durability. 24 front and rear steel bladed spokes with brass nipples will help you navigate though the rough and rocky.
