Power measurement is a crucial part of training. That's why SRAM wants to make it as easy as possible for riders to upgrade their Force AXS equipped bike with a powermeter.

The precise and extremely reliable Quarq DUB-PWR measuring unit not only helps athletes to get faster to the finish line, but is also neatly integrated into the crank shaft. Compared to the standard version, the elegantly and inconspicuously hidden technology for power measurement also brings only a small additional weight of 40 grams on the scale. The Force crank arm itself is also characterized by its low weight and increased rigidity. This is made possible on the one hand by the use of carbon. On the other hand, also the already proven DUB™ technology makes its contribution to greater durability of the entire system.

Features of the SRAM Force AXS powermeter upgrade kit

• carbon crank arm for greater stiffness and less weight
• DUB™ bottom bracket technology for increased stiffness and durability

• proven Quarq powermeter technology for maximum reliability and accuracy
• spindle-based DUB-PWR measuring unit for left-side acquisition of power data
• long battery life, sufficient for a complete season (400 hours+)
• power supply: AAA lithium battery (user replaceable)
• protection class (waterproof): IPX7 certified (to 1 meter depth for 30 minutes)
• AXS connectivity for easy setup and personalization

DUB™ | The unit of bottom bracket and oversize crank shaft (⌀ 28.99 mm) is at the heart of the DUB™ (Durable Unified Bottom Bracket) technology, which allows a symbiosis between stiffness and durability. The system approach created by integrating the chainring, crank, spindle and bottom bracket not only improves durability thanks to an optimized seal, but also raises the performance of the drivetrain to a new level.
