4iiii Precision 3+ Non-Drive Power Meter - Ultegra R8100 Info
The 4iiii Precision 3+ Non-Drive Power Meter - Ultegra R8100 bolts directly onto your existing Shimano Ultegra R8100 non-drive crank arm — no new crankset required, no complicated installation. A strain gauge bonded to the arm captures your power output with claimed accuracy of +/- 1%, while the low-profile pod is designed to sit close enough to the arm that clearance against the chainstay isn't a concern.
Pairing is straightforward: the Precision 3+ transmits over both ANT+ and Bluetooth simultaneously, so it works with your head unit, your phone, and your training platform of choice without adapters or compromises. IPX7 water resistance means wet weather and post-ride hose-downs aren't a problem. If you're running an R8100 crankset and want power data without a full drivetrain swap, this is the direct path.
