The SRAM XX1 Eagle 1x12 groupset is a complete single-chainring, 12-speed mountain bike drivetrain, designed for riders looking for 1x12 shifting with a XG-1299 cassette ranging from 10 to 52 teeth. The pack includes a trigger shifter with inner and outer cables, rear derailleur, cassette, 126-link chain and XX1 Eagle DUB SL crank.

The crank spindle is SRAM DUB, measuring 29 mm, so check that your bike's bottom bracket is compatible with this standard. The stated crank ratio is 34. Choose this groupset if you are looking for a 1x12 drivetrain with a 10-52 cassette and DUB crank.

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.
