The Soul of Steel, Unleashed.
"Rowdy, Reliable, and Ready to Rip."

Geometry of Fun

Confidence in the Chaos
This bike is engineered to party. The secret is its progressive trail geometry. Feel the unwavering stability of the slack 65° head tube as you point it down steep, technical descents.

It’s a tangible feeling of confidence that encourages you to push your limits, try new lines, and ride more aggressively than ever before. This is a geometry that’s all about maximizing your fun on the trail.
The Steel Feel
