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.

Eliminates variables caused by heat and cold to provide an unwavering record of your performance through all conditions.
Built to Last

Quarq was founded in 2006, established its factory in Spearfish, South Dakota (USA) in 2007, demonstrated prototype power meters at Interbike the same year and shipped its first power meter in June 2008. Fast forward to May, 2011, and Jim and Mieke Meyer, Quarq’s founders, officially signed the papers that would make Quarq part of SRAM LLC. When the pen was lifted, Jim reached into his backpack and handed over a previously secret power meter prototype. A complete departure from previous designs, it would shape the ground breaking SRAM RED Quarq Power Meter – the first and only power meter in a groupset. Quarq continues to define bicycle power meter development. On January 22, 2013, Quarq announced the a new level of performance in power meters, which deliver next level performance, versatility and ease-of-use in a sleek new design for today’s high-performance road racing, triathlon and cyclo-cross machines. Most importantly of all they are the easiest to set up power meters available with the user focused LED communication system. Quarq’s ease of use, reliability and performance make it the Choice of World and Olympic Champions in Road and Triathlon competition.
