SRAM Quarq RED E1 Crankset

The SRAM Quarq RED E1 crankset is a 12-speed double crankset with a power meter integrated into the chainrings, designed for riders who want accurate power data and reliable shifting. The chainrings maintain a constant difference of 13 teeth between them, helping deliver fast, reliable shifts. The carbon crank arms are 29 g lighter than the previous generation, and the meter is accurate to within ±1.5%, unaffected by temperature.

Choose the chainring combination according to the gearing you need: the supplier lists 50/37 teeth (this listing), 48/35 and 46/33. Crank arms are available from 160 to 175 mm, so check the length against your bike before buying. The colour is black and the X-Range system provides a wider range and smoother progression.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
