SRAM Apex Wide Powermeter Left Crankarm/Axle

The Apex AXS Wide DUB Upgrade Kit from SRAM includes the left crank arm with power meter axle and comes in matching Apex optics. It is used for left-side power measurement, using proven QUARQ technology. The measuring unit is hidden in the crank axle and reliably protected from water. In combination with a DUB bottom bracket, you get a durable unit with an impressive performance. Overall, the upgrade means a negligible additional weight of just under 40 g. The life of the AAA lithium battery, which you can easily replace yourself, is over 400 hours and thus covers a whole season.

Technology:
DUB™
The unit of crankshaft and bottom bracket is the heart of the DUB technology. Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is mainly the system approach through the integration of chainring, crank, spindle and bottom bracket that means better drive performance.
