XS-1275 T-Type 12-Speed Eagle Cassette

What Our Gearhead® Experts Are Saying:

"The XS-1275 Eagle Transmission Cassette is an upgrade I’d recommend to any serious mountain biker. The 520% range gives me all the gearing I need, and the optimized steps in the lower range make a big difference when climbing. The X-SYNC design keeps shifts clean and consistent, even when I’m mashing the pedals on steep sections. Plus, the Setup Cog makes installation a breeze, so I spend less time wrenching and more time riding."

Precision shifting meets rugged durability with the XS-1275 Eagle Transmission Cassette, engineered for seamless power transfer and optimized gear steps. The full X-SYNC design ensures precise shifts, even under high torque, giving us the confidence to tackle steep climbs and technical descents without hesitation.

The 520% gear range is fine-tuned for mountain riding, with revised low-end steps featuring 38- and 44-tooth cogs for smoother transitions before the massive 52-tooth bailout gear. This improved progression allows for more controlled cadence management in the toughest terrain. The mix of Pindome construction for gears 1-8 and a one-piece MINI-CLUSTER for gears 9-12 balances weight and strength, making this cassette both lightweight and durable.

Installation is effortless with the Setup Cog, ensuring correct alignment for perfect shifting out of the box. Designed for riders who demand reliability and precision, the XS-1275 Eagle Transmission Cassette sets the standard for modern mountain bike drivetrains.
