Sram GX Eagle XS-1275 T-Type 12-Speed Cassette

The cassette GX Eagle Transmission T-Type is the main reason why Eagle Transmission delivers the best inboard and outboard shifting performance under load. With its full X-SYNC design, the harder you pedal, the better it shifts. Designed for a 55 mm chainline, for less extreme chain angles across the range and greater precision. The 520% range has been optimised with larger 38 and 44-tooth sprockets before the 52-tooth sprocket to improve gear steps at the low end (compared with the Eagle 10-52-tooth cassette). Installation is simple and foolproof thanks to a clearly marked setup sprocket. It also uses a Pindome design for gears 1-8 and a one-piece mini-cluster for gears 9-12.

Technologies

Mini Cluster
The hybrid construction of the MINI CLUSTER cassette combines four small sprockets CNC-machined from a single block of billet steel with eight additional individually attached sprockets. The result: a lightweight, durable cassette with a gear range perfect for every type of ride.

X-Sync
SRAM X-SYNC 1x chainrings offer the highest level of performance and durability. The tall, square tooth edges of SRAM X-SYNC engage the chain earlier than traditional triangular teeth. The narrow, sharp tooth profile and rounded chamfers help manage a deflected chain. To deliver the best possible performance in muddy conditions, X-SYNC chainrings are designed with recesses to clear mud from the inner chain links and rollers. Designed in Germany, X-SYNC chainrings are an integral part of the SRAM 1x drivetrain. Accept no imitations.

Eagle
Eagle technology represents the latest 1x drivetrain technology from Sram. Eagle is a lighter, simpler, more durable and easier-to-use drivetrain. Eagle features all-new 1x components designed to deliver even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also offers an expanded 520% gear range, matching that of 2x11 drivetrains.

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.
