The best 650b trail bikes boast the best of both worlds, the acceleration and maneuverability of a 26'' wheel and a healthily dose of stability and rolling momentum you find with a 29er. The Easton Vice XLT 650B/27.5'' Rear MTB Wheel is designed to match those trail shredding machines. Easton didn't simply modify an exciting wheel, they built it from the ground up. The Vice XLT utilises it's wide 21mm (internal) welded alloy rim that's completely UST tubeless and rolls on 24 Sapim straight pull, double butted spokes, that have been laced 3 cross. The hub is an Easton X4 which roll on sealed cartridge bearings and are available in variety of axle configurations and the rear hub is also compatible with Sram's XD cassette body.
