Sram S975
Quarq ~
At the cutting edge of Power Metering since 2006, Quarq was purchased by
leading parts manufacturer, SRAM, in 2011. The combination of precision Quarq
metering and Sram's carbon technology has resulted in the stiffest, lightest,
and most accurate tool available for precise power training. The S975 crankset
uses SRAM's S900 carbon fiber crank arms and Sram Red chainrings. The smoothly
integrated Quarq CinQo spider with strain gauges provides +/- 2% accuracy.
Wireless ANT+ technology is compatible with several Garmin power
receiving/display units including the Edge 800, 705, 305, and 500, as well as
the CycleOps Joule 2.0. The calibration values are stored in the crank's CinQo
unit so there is no need to recalibrate if you change head units. Coin-style
battery (BA0124) lasts about 500 riding hours and is easily replaced.
Bottom Bracket specs: The S975 uses a Sram GPX cupset and is available to fit the 2 most popular
bottom bracket shells currently in use: 68mm English threaded frames. A BB-30
press-fit bottom bracket is also available. The bottom bracket is not included
(see below).
Chainrings: The S975 is available with regular 53x39 chainrings or
compact 50x34 rings. Top-of-the-line Sram RED chainrings are included with each
unit.
