A lighter, more accurate power meter completely integrated with the philosophy and performance of SRAM RED. Advances in technology and performance matched by unrivaled ease-of-use. The sleek new geometry reduces system weight and delivers clearance for oversize frames and aerodynamic chainrings. The only visible power component is the low profile, all aluminum battery case. New stress flow lifts accuracy to +/- 1.5% and makes power measurement independent from chainrings selection. Integrated electronics minimize interconnections and reduce exposure to the elements, bringing unmatched durability and reliability.
Pedal balance and ANT+ give you compatibility, flexibility and every available metric; ANT+ ID is clearly visible to aid pairing and operation
Auto zero offset ensures accurate and consistent data
LED indicator signals power on, setting zero and low battery
TT chainrings can be used without recalibration
Tool-less, user-replaceable battery is a cycling industry standard CR2032
