The Shimano FC-RC9100-P power meter: the essential performance tool for every cyclist who wants to achieve their true potential. By gathering real-time accurate and reliable power output data, you can track and analyze every detail of your ride. You can then use this potent information to tune your training and racing for maximum results. 

Power meters are one of the fastest-growing technologies in cycling. In just a few years, they have moved from being pro-only equipment to affordable training aids for amateur racers and keen recreational riders.

Technology:

Hollowtech

A lightweight crankset not only reduces the bike's weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano’s advanced forging technology has solved the problem tough the Hollowtech crank. Just like the high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very low weight. 

 

Hollowtech II

The concept of Hollowtech II technology is focused on producing a superior crankset, which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. 

Outboard Bearings: For most frames with 68 mm bottom bracket shells, Hollowtech II with 24 mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability.

High Precision Sealing: Hollowtech II cranksets have a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.

 

Hollowglide

Highly rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and more precise front shifting.

 

Power Meter

The Shimano FC-R9100-P power meter guarantees reliability. It 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 data collection for stable power measurement at various stepping positions. Plus a simple reset by a switch on the transmitter. It is compatible with third-party displays as well as Bluetooth and ANT technology.
