SRAM RED Quarq Powermeter GXP 175 53-39 (BB not included) 130BCD

The SRAM RED Quarq Powermeter is a lighter, more accurate power meter. Sleek new geometry reduces overall weight, provides clearance for oversized frames and aerodynamic chainrings. The low profile, aluminium battery case is the only visible power component. New stress flow raises accuracy to +/- 1.5% and means power measurement is independent from chainring selection. The integrated electronics help to minimise interconnections and reduce exposure to the elements, this results in durability and reliability. - A.D. Key Features: +/- 1.5% accuracy Tool-less, user-replaceable battery is a cycling industry standard CR2032 ANT+ ID is clearly visible to aid pairing and operation LED: Blinks when the power meter wakes from sleep, at the end of the ANT+™ calibration (set zero) command and when you back pedal four times to Auto Zero Power Balance: Uses crankset torque to display the ratio of power generated in the right drive stroke (first half) versus the left drive stroke (second half) for each crank revolution Omnical: Power measurement is independent from chainring selection. Swap chainrings without impacting accuracy. Rain, mud and snow the waterproof design will survive the worst conditions
