A lighter more accurate power meter completely integrated with the philosophy & performance of SRAM RED. Advances in technology & performance paired with unrivaled ease-of-use. The sleek new geometry reduces system weight & delivers clearance for oversized frames & aerodynamic chainrings. The only visible power component is the low profile all aluminium battery case. New stress flow lifts accuracy to +/- 1.5% & makes power measurement independent from chainring selection. Integrated electronics minimize interconnections & reduce exposure to the elements bringing unmatched durability & reliability.
