The Roval Alpinist CLX Rear HG is the rear wheel from Specialized’s lightweight Alpinist CLX wheelset, designed for climbing and fast road riding. It features a 33 mm-deep carbon clincher rim with a 21 mm internal width that performs best with 25–28 mm tires. The wheel is built with 24 DT Swiss Aerolite T-head spokes laced one-cross/two-cross (2:1) to a Roval AeroFlange Disc hub. Inside, DT Swiss 180 Ratchet EXP 36-tooth internals and sealed DT Swiss SINC ceramic bearings drive the Shimano HG freehub body. The wheel is hand-built to a weight of approximately 694 g (including rim tape and valve) and is tubeless-ready for low-pressure riding.
