The SRAM Quarq Red BB30 delivers ANT+ wireless power data from a lightweight, carbon Exogram™ crankset. The integrated Quarq unit provides readings accurate to ±1.5% regardless of temperature and features a simple CR2032 battery with up 300 hours of ride time. Power Balance™ technology captures left and right strokes, and OmniCal™ makes it possible to run most aftermarket chainrings without affecting data accuracy. ANT+™ transmission ensures easy compatibility with leading display units like the Garmin Edge® computers, and an integrated AxCad™ accelerometer also transmits cadence measurements without the need for a magnet. SRAM's Exogram™ crank construction features a large, hollow carbon cross section that extends all the way to the CNC-machined alloy spider. The result is incredibly light yet uncompromisingly rigid to maximize efficiency.
The SRAM Quarq Red BB30 Crankset is available in Standard 130 BCD and Compact 110 BCD spider configuration in various arm lengths. For use with BB30 compatible frames only. Includes chainring bolts. 145mm "Q-Factor." 556 g approximate weight (172.5 mm, 110 BCD).
