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 Cannondale SI, SISL or SISL2 cranksets with a removable spider, the Cannondale AI (Super Boost) chainline and a 1x drivetrain. The chainline is 55mm; for a Boost chainline the adapter ZB-SAX-00104-M01.SBNG is needed. Takes a 104 BCD chainring (not included). Mounting the right crank arm needs the power2max lockring tool for FSA, Cannondale and Specialized cranks (ZB-SAX-WZFSA-K01.0000). Our workshop can fit the power meter to your crankset and pair it with your head unit as a separate service, not included in the price.
