Description
The Stages Cycling G3 Power L Shimano GRX RX810 Power Meter allows accurate off-road power measurement to aid training and racing. The unit adds just 15 grams to the weight of the base GRX crank arm and is accurate to +/- 1.5%, with the capacity to measure up to 2,500 watts. Automatic temperature compensation ensures that the data is accurate even in changeable conditions. The power meter has a 200+ hours battery life and the CR2032 battery can be easily replaced without recourse to any tools whilst firmware upgrades are performed wirelessly.
To help find your current crank model, check the inside of the crank arm for the model and length. The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm Allen key wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
Still unsure? See this illustration for a guide of where to measure.
