Simple, reliable data

The NGeco measures total power and cadence at the spider, so there are no pedal or crank-arm sensors to swap between bikes. Active temperature compensation and automatic zero-point adjustment mean no manual calibration, and the CR2450 coin cell is user-replaceable and lasts up to 300 hours.

Compatibility & fit

For Shimano MTB direct mount cranksets with a removable spider in a 1x setup; compatible cranksets include M9100, MT900, M8100, M7100 and M6100. Works with Boost and standard chainline setups.
