A lighter, more accurate power meter completely integrated with the philosophy and performance of SRAM Red 22. Advances in technology and performance paired with unrivaled ease-of-use. The sleek new geometry reduces system weight and delivers clearance for oversized 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 chainring selection.
The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.
Quarq technology powers SRAM’s road power meters including the groundbreaking SRAM RED Quarq Power Meter.
KEY FEATURES:
- Powermeter crank system is compatible with ANT+ wireless devices including Garmin, iBike, CycleOps/Saris and training software such as TrainingPeaks (& WKO+), Strava, Golden Cheetah, or Garmin Connect (all available separately)
- Updated strain-gauge arm design with PowerBalance and power sensor with LED indicator (battery level & programming), no-tool CR2450 battery access, and GXP or BB30 cadence/activation magnet system
- Auto zero-offset, pedal balance, and impoved accuracy to within +/- 1.5%
- Optimized for use with the New-Red (Yaw) drivetrain including hidden 5th-arm spider design with Yaw-compatible 2x11 speed chainrings (also works with Yaw-compatible TT chainrings without recalibration)
- Separate Qalvin app and Wahoo Key ANT+ transceiver available for iPad/Phone/Touch enables calibration and advanced diagnostics (Zero Offset calibration available on select Garmin devices)
- 1-piece, unidirectional carbon fiber arms with an alloy Powermeter spider and integrated 30mm-aluminum (BB30) or 24mm-steel (GXP) bottom bracket spindle (BB30 version utilizes a non-drive arm/spindle integration to reduce packaging size)
- *BB30 or PF30 bearing sets sold separately (see listings in Truvativ)
- *GXP 68/73mm or BB86 adapter cupsets sold separately (see listings in Truvativ)
