The invisible technology that helps improve your performance is finally available with the Rival power meter. Fully integrated into the DUB axle, this system is easily mounted on any bike without adding bulk. Simply install it, connect it to your 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 last you through the entire season without needing 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. In addition, the Rival sensor is waterproof to IPX7 standard, resistant to immersion up to 1 metre deep for 30 minutes.
