Shimano Ultegra FC-R8100-P Power Meter Crankset – 2x12 Speed, 52-36T, Dual-Sided Power Measurement

Ready to take your training to the next level?

The Shimano Ultegra FC-R8100-P Power Meter Crankset gives you pro-level data without the pro-level price tag.

This is a dual-sided power meter, meaning it measures output from both legs independently – and it’s accurate to within 1.5%.

That’s huge for tracking imbalances, efficiency, and overall effort.

It’s designed for 12-speed setups with a 52-36T chainring combination, which is a popular choice for road cyclists who want a good balance of speed and climbability.

Setup is straightforward thanks to ANT+ and Bluetooth LE connectivity – pair it with your bike computer or smartphone app (like Garmin, Wahoo, or Strava) and you’re ready to roll.

Battery life is solid, and recharging is easy via USB.

Plus, the Hollowtech II construction keeps things light and stiff, so you’re not sacrificing performance for data.

Whether you’re training for a race, following a structured plan, or just curious about your power output, this crank delivers reliable numbers ride after ride.

The design is sleek and integrates seamlessly with Ultegra and Dura-Ace groupsets.

Installation is best done by a bike mechanic if you’re not comfortable with crank swaps, but once it’s on, calibration is simple.

If you’re serious about improving your cycling, having a power meter is a game-changer – and the Ultegra FC-R8100-P offers Shimano’s trusted quality at a more accessible price than the top-tier Dura-Ace version.
