Technology:


Exogram™:
The hollow carbon construction starts in the crankarm and extends into the crank's spider, maximizing the stiffness to weight ratio.

Quarq™:
QUARQ technology powers SRAM's road power meters including the groundbreaking SRAM Red QUARQ power meter.
How power meters work:
Power meters calculate power by measuring the torque (pedal force) and the angular velocity (cadence). Power = torque x cadence.
When you press on the pedals, all parts of the bikes drivetrain displace (flex) slightly under the load. Power meters are designed using finite element analysis to displace in a very controlled manner in specific locations in response to applied load. Strain gauges are used to measure the displacement and thus calculate the applied torque. Reed switches are used to calculate cadence.
SRAM power meters use a proprietary strain gauge arrangement and precision digital circuitry to delivery high accuracy and low power consumption for optimal battery life.

Inside QUARQ power meters:
ANT+™: A wireless standard for bicycle electronics that ensures interoperability between sensors and bike computers from different manufacturers.
OmniCal™: Power measurement is independent from chainring selection. Switch from road to TT chainrings without impacting accuracy. No recalibration necessary.
Power Balance™: Displays the ratio of power generated in the right drive stroke (first half) versus the left drive stroke (second half). Let you work on an equal pedal stroke over 360 degrees of rotation.

Excellent Product ! Perfect upgrade, It can replace almost any 110 BCD compact crankset. You can re-use your current chainrings as soon as they are BCD110. You just need to buy the GXP Bottom bracket that fits your bike. Power Mesurement is accurate, it's also one of the lightest and cheapest left/right powermeter on the market. It takes 30s to pair with garmin edge 1000 or 520. 15s if you read the manual first... Measure Power, left/right balance and cadence.
