SRAM Rival E1 XPLR DUB Wide Left Crank with Power Meter

The SRAM Rival power meter features invisible technology that enhances performance without compromising on aesthetics or ease of use. Fully housed within the DUB axle, this discreet system is easy to install on any bike, without adding any visible components or altering the design. Simply install it, connect it to your bike computer, and set off.

The sensor measures power on the left side via the axle and then accurately calculates total power. It offers an impressive battery life of over 400 hours, covering a full season without worrying about the battery. When replacement is needed, the AAA lithium battery can be quickly changed by the user without any special tools.

Designed to withstand the most demanding conditions, the system features IPX7-certified water resistance, capable of withstanding immersion to a depth of one metre for 30 minutes. Thanks to the use of the DUB interface, the crankset is simpler, more robust and more reliable. Despite the integration of this advanced technology, the whole unit remains extremely lightweight, adding less than 40 grams compared to a standard crankset.
