Number of gears 12-speed
Suitable forSram XD
Cassette Ratio 10 / 50


In keeping with the XX1 and X01 groupset, there's now a 12-speed version in the guise of the affordable Sram GX Eagle groupset. The Sram GX Eagle cassette offers a 500% gearing range and features the latest technologies. The XG-1275 cassette offers sprockets ranging from 10t up to 50t. This gives you speed on the flats and allows you to take on any mountain you'd want to.

The cassette runs as follows: 10t, 12t, 14t, 16t, 18t, 21t, 24t, 28t, 32t, 36t, 42t and 50t. It is being held together by pins. This FULL PIN™ technology doesn't just make the cassette very light, but highly durable as well. The open X-DOME™ design allows mud and other dirt to quickly fall away. This improves both gear shifts and durability.

The 12 speed cassette is compatible with existing XD drivers. This does mean that the spacing between the cogs has been reduced, thereby also narrowing the chain design. X-Glide 2 is the latest generation of the Sram X-Glide technology, and is optimised for the Eagle 12-speed cassette. It ensures fast and accurate shifts under load across the range of the cassette and enhances the grip of the chain on the larger cogs.

cracking price for Eagle

Great for the price. Fantastic range, although ratios could be spaced a bit more evenly.
