The crankset is the heart of your bicycle and where you’ll find the SRAM Red Quarq power meter. The sole job of the crankset is to convert the effort from both legs to forward motion, making it is the perfect place to measure power.

The crank arms themselves have a top of the line Exogram hollow carbon fibre construction that not only cuts back on weight, but also maximises strength and speed. ANT+ transmission is built in allowing the crank to transmit to your ANT+ enabled bike computer. Quarq's free Qalvin app allows you to set up the crank by setting the zero offset, checking battery voltage and updating firmware. The Quarq features AxCad technology that switches the power meter on when cranks start turning so one, you save battery and two, you get accurate power, cadence and speed measurements. With an accuracy rating of +/- 1.5% and a IPX7 waterproof rating that means the crank can be submerged in one metre of water for up to 30 minutes.

The crankset is compatible with SRAM 1x or 2x road drivetrains so you can fully customise your chainring setup to suit your riding, whether that be cyclocross, TT or road riding.


Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.

Please Note: Chainrings sold separately
