SRAMRED DZero Power Meter - BB30 - Leistungsmesser - Kurbeln (ohne Kettenblätter)

Quarq power meters use their patented direct-force technology to precisely measure your physical performance throughout your ride. Their meter is located in the crankset, the heart of the bicycle, and because it gathers data from both legs, and it's located at the precise point where muscle energy is converted to forward movement, the power meter spider is the most accurate place to gather power data. 10K Temperature Compensation Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions.
