ST 250 Frame
The new ST 250 Titanium Mountain Bike Frame is built for riders who love the challenge of the climb and the freedom of the trail beyond it.
Designed around a 120mm travel fork, the ST 250 delivers an exceptional balance of climbing efficiency, trail precision, and the natural ride quality that makes titanium so special. Our signature Helix twisted down tube and diamond-shaped top tube work together to enhance frame stiffness, improve power transfer, and deliver a responsive, confident feel when the trail turns steep. Every pedal stroke translates into forward momentum, giving you the efficiency to conquer demanding climbs and the control to enjoy every mile along the way.
Adding another layer of versatility, the ST 250 features adjustable sliding dropouts, offering compatibility with a wide range of modern drivetrain and gearing configurations. Whether you prefer the simplicity of a single-speed setup or the performance of the latest geared groupsets, the ST 250 adapts to your riding style. Lightweight, remarkably capable, and built with the lasting durability of titanium, the ST 250 is more than a mountain bike frame. It's an invitation to find your next challenge, push your limits, and take the trail wherever it leads.
