Quarq DFour91 Power Meter Crank

Great savings on a reliable power package featuring the Quarq Powermeter with a Garmin Edge 500. Call us at 800-627-6664 to order or indicate crank length, chainrings, bb compatibility and blue or grey color choice on the Edge 500 in the comments section of the online order form. Heart rate monitor and speed/cadence kit not included - available separately.

The Quarq SRAM S975 wireless powermeter includes a crankset with CinQo powermeter, battery and cadence magnet. The Quarq CinQo powermeter employs ten strain gages with a total of 20 grids in a proprietary arrangement and is accurate to +/- 2%. The CinQo will complete a power reading every crank rotation. So, if you are pedaling at 90rpm, power data will be received by the computer every two-thirds of a second. The CinQo measures the combined output of both legs (not each leg separately).

Quarq powermeters are manufactured and assembled in South Dakota. Final calibration, quality control and shipping takes place in Spearfish, South Dakota.

The Garmin Edge 500 GPS-enabled bike computer features a sleek, lightweight design. It is designed for cyclists wanting the most out of their training and racing and is one of our most popular computers thanks to its highly functional design.

During your ride, Edge 500 measures your speed, distance, time, calories burned, altitude, climb and descent, and records this data for your review. For extra-precise climb and descent data, Edge 500 also incorporates a barometric altimeter to pinpoint changes in elevation. Other helpful training features include a Courses feature, which helps you compare successive rides over the same route, as well as Auto Pause, Auto Lap and temperature readings. Edge also alerts you if you're moving, but the timer is not running
