Unable to load collection availability
Description
The INPEAK POWERCRANK-E TWIN2 LR Shimano GRX RX820-2 Power Meter Chainset incorporates two independent power meters, one on each crank arm of the Shimano GRX FC-RX820-2 gravel chainset (double chainring), for comprehensive dual-sided measurement on the road and on gravel.
Strain gauges on both sides of the crank arms deliver ± 2% measurement accuracy across a range of 20 to 2000 W, along with cadence, torque effectiveness, pedal smoothness and left/right balance. Cycling Dynamics is available on certain Garmin cycle computers and watches. The discreet, IP67-rated waterproof enclosure, combined with active temperature compensation (ATC), ensures reliable readings from -5°C to +50°C in all conditions.
Both sensors are powered by rechargeable Li-Po batteries, charged using the supplied magnetic USB cable, for up to 90 hours of battery life per side. ANT+ and Bluetooth Low Energy connectivity ensure compatibility with most cycle computers, watches and apps such as Zwift, while the INPEAK Manager app handles firmware updates and scale factor adjustment.
Designed and manufactured in Poland, each sensor is individually calibrated before dispatch. A premium solution for gravel riders seeking complete, reliable power data on every terrain.
