Part Details
  • With several years of development and working closely with professional teams you can expect extreme accuracy from Shimano's first fully integrated power meter HollowTech II 11-speed Dura-Ace chainset
  • 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 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
