XM521 27.5in Boost Wheelset

High volume trail and plus-sized tires offer a boost of traction when you're riding loose or chunky terrain, and with the DT Swiss XM521 27.5in Boost Wheelset they find an ideally matching counterpart. Boasting a 35mm internal width that works well for 2.4 - 2.8in tires, these burly aluminum wheels offer all the support needed by the most aggressive of riders, yet keeps the weight reasonably low to help counteract the added weight of larger tires. The rims are laced to DT Swiss' venerable 350 hubs with their bombproof ratchet drive system, which happens to be one of the most reliable hub sets on the market. 28-spokes front and rear offer just the right balance of stiffness and compliance, and the wheels come in Boost spacing front and rear with a SRAM XD freehub.
