4iiii PRECISION Power Meter For Shimano DURA-ACE 9100

Shimano’s lightweight evolution of the FC-R9100 is now available as a 4iiii PRECISION power meter! Used by the World Tour teams Quick-Step Floors and Bora-hansgrohe, the 4iiii PRECISION Power Meter for Shimano DURA-ACE 9100 is the lightest, most affordable direct force power meter available. The added weight of the 4iiii PRECISION is only 9 grams. Even better yet, it is accurate to within +/- 1.0%.

The 4iiii PRECISION is a left-only crank arm-based power meter and replaces your current left side crank arm. The 4iiii takes the power that is generated by your left leg and doubles it in order to determine your total power output. All PRECISION models run off a CR2032 battery, feature approximately 100 hours of battery life and support both ANT+ and Bluetooth SMART wireless protocols.

    Dollar for dollar, I think this is the best single-sided PM going for those on a budget. It’s been 100% reliable in all sorts of messy conditions and has proven to match up very well with power numbers from my Kickr. PM City shipping was super quick and pricing was very fair. Will be a repeat customer.

      Hi Cendres. Thanks for the review! Not only are you getting accurate, consistent data…but you got a DURA-ACE 9100 crank arm to boot – not too shabby 🙂 We hope you continue to enjoy it.
