Upgrade your mountain bike for a better ride and lighter weight with Bontrager's Rhythm Elite TLR 27.5/650b Wheels. These tubeless-ready hoops feature tough, 6061-aluminum rims, sealed-bearing hubs, stainless-steel spokes and locking aluminum nipples to strike the perfect balance of burliness, lightness, and ride quality. And, the wide 28mm rims provide you with a stable platform for running fat, grippy all-mountain knobbies and the convertible axle plays nicely with quick-release skewers and 15mm through axles.
