Shimano Dura-Ace R9100-P Power Double Chainset

The Shimano Dura-Ace R9100-P Power Double Chainset has been totally re-engineered to provide you with the optimum balance of low weight and stiffness. It features Shimano's 4-arm, hollow forged aluminium spider, which is compatible with various chainring tooth count options. In a first for Shimano, this model is also equipped with an integrated power meter with Bluetooth and ANT+ connectivity, providing you with in-depth power data to help to analyse and improve your performance.

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. This battery can be updated wirelessly and is discretely mounted to the chainset's 4-arm spider. This means you can change the chainrings without having to worry about affecting the power measurement.

Lighter and stiffer

Although the chainset's spider arms are noticeably wider to increase the stiffness, Shimano has still managed to lower the overall weight by 7g over the previous versions of Dura-Ace. The chainset has been adapted to ensure it is compatible with disc brake road bikes that have 135mm rear hub spacing and shorter chainstays. Thanks to its wider chainring spacing this extra clearance has been introduced without any increase to the Q-factor.

Please note: Bottom bracket is NOT included.

Features:

  • Integrated power meter with ±2% strain gauge power measurement accuracy
  • Power meter is waterproof and has a rechargeable battery
  • Connects via Bluetooth or ANT+ for compatibility with most cycle computers
