The HollowTech II 11-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders. Key Features: 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 11-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 Weight: 609 grams (50-34T)
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.

Accurate Readings in all Conditions Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position. Easy to Maintain The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement.

E-Tube compatibility means that the function of the shift paddles can be customised to suit the rider. The shift paddles now feature a more defined "click" and have been extended in length for more confident and comfortable shifting. The 9150 shifters now include Synchro-shif technology that automatically moves the rear derailleur when the front ring is changed or moves the front chainring with the rear shifts to optimise chainline and drivetrain efficiency.
Supreme Aerodynamic Performance Advantage The 40mm rim depth and profile provide a supreme aerodynamic advantage in terms of speed and stability while being exceptionally stiff. The wide rim internals provides an optimised tyre profile when using wider tyres, specifically 28mm tyres. This increased rim width provides the perfect tyre profile/shape to create greater contact patch with the ground, increasing speed, grip and adding an aerodynamic benefit. Stiffness, Stability and Highest Levels of Performance Equipped with straight-pull, stainless steel bladed spokes, laced with Shimano cold-forged aluminium hum front and rear. This wheel is designed to roll on 12mm thru-axles to increase stiffness, stability and safety to even higher levels of performance; this wheelset is perfect for Racing, Endurance days in the saddle, training or exploring new routes in the hills.
