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 cassette with 10-52 teeth). 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 machined using CNC from a single block of billet steel with eight individually secured 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 provide the best possible performance in muddy conditions, X-SYNC chainrings have been 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, stronger 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.

The product may be shipped in an aftermarket box or OEM packaging depending on supply

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.
