Adjust the sus for full send

Adjust the sus for full send

Easily adjust the leverage rate with a quick flip of a chip. Use the "Less Progressive" setting for a smoother, more cushioned ride ideal for rough terrain and sharp bumps. Switch to the "More Progressive" mode when tackling larger obstacles to prevent bottoming out, or if you're opting for a coil shock.

 
Transition to transmission

Transition to transmission

The SRAM Eagle T-Type transmission attaches directly to the frame, eliminating the need for an old-school derailleur hanger. This creates a more durable, streamlined system that not only looks sleeker but also delivers greater precision under load and simplifies the setup process.

 
Size-specific stays

Size-specific stays

Chainstays designed to match each frame size ensure agile handling for smaller riders while enhancing front wheel traction during climbs for taller riders, delivering a well-balanced ride across all sizes.
