Built using lightweight and trail tough T800 Carbon Fibre, around a 100-120mm travel fork, or, with a Selcof suspension adjusted full carbon rigid fork, that will give you maximum efficiency and weight saving. The Whippet is as fast and sleek as its namesake. Though it’s not just for the pinned race day. Stealth routing for a dropper allows you take on technical descents, and modern XC geometry is suited for both backcountry exploits and endurance adventures.
SX Eagle
The new SX Eagle is your entry point to the SRAM Eagle Ecosystem. Sharing many features with the rest of the Eagle Ecosystem like the proven SRAM 1x-specific X-HORIZON™ body design, it can accommodate up to 10-50T cassettes. Eagle is a lighter, simpler, more durable, and easier to use drivetrain.
Reliable, wide range, 1x gearing
An 11-50 cassette provides a huge, relible, gearing range with a single 32 tooth crankset utilising DUB technology. Enough range to ensure you can fly downhill or comfortably spin up the steepest climbs.
Level hydraulic brakes
The SRAM Level brake levels the playing field with power and reliability stuffed into a lightweight package. SRAM’s direct link design produces a solid, positive feel the second you squeeze the lever. It offers a no-nonsense solution to give you precise control.
