Integrated Power Meter
The power meter is built into the left crank arm
The "Wide" designation means the crank arm and spindle are designed to accommodate wider frames and larger tires commonly used in gravel and adventure riding. This wider Q-factor (the distance between the pedal attachment points) helps maintain a comfortable and stable riding position on rough terrain.
- The upgrade kit features SRAM’s DUB (Durable Unified Bottom Bracket) technology, which includes a 28.99mm spindle compatible with various bottom bracket standards. DUB technology enhances durability and ensures a secure fit with your frame, improving overall performance
- The power meter uses ANT+ and Bluetooth technologies to wirelessly transmit power data to compatible cycling computers, smartphones, and training apps. This allows for real-time monitoring and detailed analysis of your performance
- The power meter includes automatic calibration and temperature compensation, ensuring consistent and accurate power readings without the need for frequent manual adjustments. It is powered by a user-replaceable lithium AAA battery, providing approximately 400 hours of riding time
