Bike Framset super light carbon fiber road frame SA-908

The frame is the heart of any bike. Whether you prioritize speed, lightweight design, or aerodynamics, the SA-908 road frame delivers exceptional performance, speed, and comfort.

Our carbon frames feature a standard UD black matte or glossy finish. Raw UD carbon weave, custom logos and colors are also available.

Package includes:

Frame, seat clamp, fork, seat post, integrated handlebar, headset bearings, spacers, front & rear thru-axles.

It supports 700C×42mm/650B×2.1-inch wide tires (easily compatible with tires up to 50mm wide), maximizing riding comfort on rough surfaces. Whether you're traversing gravel, mud, rocks, or switching to paved roads, it can reliably handle various terrains and confidently tackle any challenge.

More importantly, it features the Innegra Fiber suspension system—eliminating the need for a rear shock absorber while achieving a "micro-dampening" effect through the properties of the fiber material. Riding it, you'll immediately feel the difference: it's completely different from ordinary hardtail mountain bike frames, filtering bumps more smoothly and making long rides less tiring.

The frame features a UD carbon fiber texture and is available in matte/gloss black finishes by default; it also supports custom logos and paint jobs, allowing you to customize the look of your gravel bike!
