SRAM Rival E1 DUB left crank with power meter

The invisible technology that helps improve your performance is finally available with the Rival power meter. Fully integrated into the DUB axle, this system fits easily onto any bike without adding bulk. Simply install it, connect it to your bike computer, and you’re ready to ride.

This sensor measures power on the left side via the axle, then accurately calculates total power. With an exceptional battery life of over 400 hours, it will see you through the entire season without the need for frequent recharging. The AAA lithium battery is also easily replaceable by the user.

Designed to last, the DUB crankset guarantees robustness and ease of use. Furthermore, the Rival sensor is waterproof to IPX7 standard, withstanding immersion up to 1 metre deep for 30 minutes. Despite this advanced technology, it remains lightweight, adding less than 40 grams compared to a standard crankset, for optimal comfort on your rides.
