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.

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 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

170MM, 172.5MM AND 175MM AVAILABLE. 50/34; 52/36 OR 53/39 RATIO’S AVAILABLE.
