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.
The HollowTech II 12-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders Hollow outer chainring, giving vast improvements in rigidity and increased weight savings The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength The teeth have been developed to work only in conjunction with the 12-speed chains for improved contact providing more efficiency and improved power transfer There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
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.
