SRAM FORCE AXS QUARQ D2 DUB Power Meter Crank Arm

The SRAM FORCE D2 DUB power meter crank arm incorporates Quarq technology for accurate power measurement, essential for training. 

The DUB-PWR power meter, integrated into the bottom bracket axle, measures left-side power to calculate total watts, offering a discreet, lightweight solution. Proven reliable and accurate, it is compatible with more bikes than ever. Its user-replaceable AAA lithium battery provides over 400 hours of battery life, enough for a full season of riding. 

The DUB bottom bracket adds durability and simplicity, while IPX7 water resistance protects against immersion in up to 1 metre of water for 30 minutes. Weighing less than 40 g more than a standard chainset, this hidden power meter helps you reach the finish line faster.

The SRAM FORCE D2 DUB power meter is made from carbon for an optimal combination of low weight and strength, delivering high performance without excess weight.
