After years of development and collaboration with professional teams, Shimano introduces its first fully integrated power meter, the HollowTech II 12-speed Dura-Ace chainset, offering exceptional accuracy.

Designed for serious cyclists, the Dura-Ace FC-R9200-P power meter provides reliable, waterproof, dual-sided power measurement. It features a rechargeable battery and supports BluetoothLE and ANT+ connectivity, making it a user-friendly training tool.

The Dura-Ace FC-R9200-P power meter meets the needs of data-driven cyclists. Its integrated, waterproof design ensures all-weather reliability while delivering precise data, including left/right balance. The rechargeable Li-ion battery and BluetoothLE and ANT+ connectivity facilitate easy setup and use.

Features:

• Accurately calibrated strain gauges are integrated inside both left and right crank arms, this provides a stable measurement system through rotation from both sides for extremely precise data
• +/-2% accuracy of strain gauge measured power
• Bluetooth and ANT+ with wireless firmware update and data acquisition system
• Easily rechargeable integrated battery with fully waterproof reliable electric system
• 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 cold forged hollow crank arms have 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
