Power Arc

Brand: Specialized

The Power Arc is the more curved variant of the short-nose Power, introduced around 2019. It keeps the Power's stubby profile and wide pressure-relief cutout but adds rounder edges and a more pronounced side-to-side and front-to-back curvature (the 'arc'), letting riders slide and reposition more freely than the flatter standard Power. It is aimed at riders who move around on the saddle or shift between positions. Specs below are for the Power Arc Expert with hollow titanium rails; the S-Works version uses carbon rails and shell and drops to about 134 g.
