Building on what it learned with its Gen 2 Version, Stages has developed its technology even further for this latest model. Built on to a non-drive-side Stages Carbon crank arm, it is individually calibrated to ensure its accuracy. This particular Stages crank arm is built to retrofit SRAM, Race Face, and Easton cranks with Stages Power, with an additional spindle purchase. No additional spindle purchase is required for FSA 386EVO cranks. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data. Stable Connection Stages have made additional improvements to the Bluetooth and ANT+ transmitters and the accelerometer. This ensures a stable and powerful connection with your cycle computer is maintained and a faster sampling rate for more up-to-date feedback on your performance. Compatibility: · Fits 30mm spindle BB30, OSBB and 386EVO bottom bracket standards by way of appropriate Stages 30mm alloy spindles (sold separately) · Frame Compatibility: Most frames · Device Compatibility: ANT+, Bluetooth Smart ready · Software Compatibility: StagesLink, Training Peaks, Strava, Garmin Training Centre and others Stages Cycling spindles for 30mm are available in five options to purchase separately: · For SRAM Red 22 BB30 · For SRAM Force 22, Rival 22, Force/Rival CX1 · For 2015 model/year or newer SRAM BB30 mountain cranks with a 9mm driveside spacer · For 2015 model/year or newer SRAM BB30 mountain cranks with a 15.5mm driveside spacer · Race Face Next SL In The Box: · Power meter · High-quality CR2032 coin cell battery · Product identification card with serial number and ANT+ I.D. · Number user guide

Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The crankset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The Compact version offered here features a 50.34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains. Please note: Bottom bracket is NOT included.
