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.
GX Eagle
This GX groupset offers impressive performance with plenty of gears. Sharing many features with the higher end of the Eagle Ecosystem like the proven SRAM 1x-specific X-HORIZON™ body design, it can accommodate up to 10-52T 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 gearing range with SRAM’s top of the range aluminium 32 tooth crankset utilising DUB technology. Enough range to ensure you can fly downhill or comfortably spin up the steepest climbs.
G2 hydraulic brakes
The SRAM G2 delivers premium value braking without compromise. Powerful 4 piston callipers provide awesome single finger stopping power and reach adjust makes it easy to adjust your lever for maximum control. Think consistency, reliability and trust.
