Alpha II Disc is upgraded on the rims. The upgraded U/V rim profile combines the aerodynamic stability of a U-shape with the wind-cutting efficiency of a V-shape, delivering reduced drag and better performance in crosswinds. This design also enhances lateral stiffness for improved power transfer during sprints and climbs, while offering smoother tire-to-rim transitions for better handling, comfort, and versatility across varied terrains. It is an affordable road bike wheel with a 6-pawl freehub and 72 engagements for a lightning-fast response. Boasting a 28mm external width and 23mm internal width for superior strength and performance, it also comes with the option of ceramic bearings for a smooth ride.
