Stages Cycling Power Meter G3 L (Stages Carbon GXP MTB)Ridden by three TDF winners and multiple championship winners to victory, Stages power metres have been proven to be able to perform at the most elite level of the sport. This single-sided power meter provides readings with an accuracy of within +/- 1.5% and can be used with any SRAM MTB drivetrain.Increased AccuracyStages has built on what it learned when producing its Gen 2 model, by developing the technology even further for increased accuracy of the readings. This Gen 3 model is assembled within a SRAM Mountain Bike GXP non-drive side crank arm and is individually calibrated. This ensures it provides an accuracy that can be trusted by avid amateurs and professionals on the World Tour.Reliable Readings In Any WeatherTo ensure the measurements remain consistent in any weather type, Stages introduced a feature that’s never been seen integrated into a power meter before. The feature is “Active Temperature Compensation” and Stages added this technology to account for any sudden temperature changes that you might encounter on your ride. If temperature changes are not accounted for, it can result in false and inaccurate data.Strong ConnectionOther improvements include more powerful Bluetooth and ANT+ transmitters. These improvements ensure the power meter provides a powerful and stable connection with your cycle computer is maintained. Also, thanks to the addition of a more advanced accelerometer, the power meter has a faster sampling rate for more up-to-date feedback on your performance.Features:  Accelerometer based cadence measurement     Wirelessly upgradable firmware     LED indicator displays battery level     Updated accelerometer and addition of gyroscope     Upgraded BLE and ANT+ radios offer a 6X improvement of data transmission strength     Battery Life: 200+ hours (coin cell: CR2032) when used as a single sided meter     Power Range (Watts): 0 to 5000     Cadence range (rpm): 10-220     Water Resistance Rating: IPX7  Weight: Only adds 20g to base crank armCompatibility:     Compatible with all SRAM GXP Mountain Bike drivetrains     Frame Compatibility: Most frames     Device Compatibility: ANT+, Bluetooth Smart ready      Software Compatibility: StagesLink, Training Peaks, Strava, Garmin Training Centre and othersIn The Box:     Power meter     High-quality CR2032 coin cell battery     Product identification card with serial number and ANT+ I.D.     Number user guideBuy Stages Cycling Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
