4iiii R9100 Shim Precision Pro DUAL Sided PowerMeter


Ridden by the pros, PRECISION PRO dual-side power meters deliver all the benefits of our left-side model (exceptional accuracy, lightweight design, ANT+ and Bluetooth compatibility, 3D powermeter technology), plus a specific breakdown of left and right wattage. Perfect for those who need specific power output from each crank side, or anyone who simply wants the best power meter on the market.

The PRECISION PRO Ride Ready comes pre-installed on a new Shimano DURA-ACE FC-9000 series crankset you purchase from us.
