It’s just over a year since the launch of SRAM’s premium pricED XX1 and XO1 twelve speed Eagle transmissions. Now GX Eagle gives all the benefits but with a more down to earth price tag and only a small weight penalty.

We’ve always been fans of the single chainring approach to gearing and when SRAM launched the groundbreaking XX1 1×11 transmission five years ago we were sold on it after one ride. Here was a drivetrain that was designed as a complete system with every component having a redesign. And so it was with the Eagle twelve speed – an all-new chainring, chain and the cassette with a huge spread of ratios. ‘A total revamp, an extra gear and a massive 10–50 tooth spread!’ is how we summed up this new innovation. This wide range cassette allowed either an incredibly low gear ratio, or the ability to increase the highest gear (using a larger chainring) while still giving you a bottom gear to climb most gradients.
