power2max NGeco Praxis DOON Carbon Gravel Power Meter Crankset

The power2max NGeco Praxis DOON Carbon Gravel Power Meter Crankset is a lightweight carbon crankset designed to tackle any trail. The NGeco is the newest model in the power2max line-up. It offers dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance. The NGeco is also accurate to +/- 2.0%, has an auto-zero feature so your data is always accurate and accelerometer-based cadence measurement. This power meter also uses a CR2450 replaceable battery that provides 300-400 hours of battery life. This is perfect for long adventures where rechargeable power meters may not provide long enough battery life.

Praxis DOON carbon crank arms are lightweight at only 342 grams (172.5 mm) and use a 30 mm spindle. This makes these crank arms compatible with a range of bottom brackets. The DOON cranks also have an updated preload collar which ensures reliability and easy adjustment.
