Key Product Details
This power meter uses a 30 mm spindle and is therefore compatible with 30 mm bottom brackets. It comes with power2max gravel chainrings and features a GRX 47 mm chainline. The power meter gives you a narrow road Q factor vs. the slightly wider Q factor inherent in GRX cranks. See Compatibility tab for more information.
The power2max power meter measures power at the spider and is therefore able to measure power from both legs. This NG version is also able to measure your left vs. right leg power balance.
Dual-leg power measurement, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration), 5-year warranty. See Specs tab for more information.
