Two of the World Tour teams competing at this year's 2017 Tour de France will be among the first to race Shimano's new crank-integrated Dura Ace power meter (FC-9100-P).
Team Sunweb's Ramon Sinkeldam, Roy Curvers, Nikias Arndt and Laurens Ten Dam used the power meter during the first road stage of this year's tour, which started in Dusseldorf on Saturday 1st July.
The FC-R9100-P unit is Shimano’s first power meter. It retains the Dura-Ace unique asymmetrical four-arm spider construction, but with a ‘brain’ mounted on the inside and with strain gauges on the crank arms.
The power meter boasts a completely sealed, crank-integrated design that is waterproof in all conditions. The built-in battery is recharged by a small magnetic adapter, so there is no cover to open.
The direct instant response system ensures accurate real time data collection for stable power measurement at multiple steps throughout the crank rotation with a +/-2 percent accuracy rating and the ability to measure separate left and right power.
