This high-performance carbon gravel bike frame is engineered for versatility, durability, and comfort across diverse terrain. Crafted from lightweight, high-modulus carbon fiber, it balances stiffness and compliance to deliver efficient power transfer while dampening vibrations from rough gravel roads and uneven trails.
The geometry is purpose-built for adventure: a sloping top tube (B) and extended reach (M) provide a stable, confident riding position, while the relaxed head tube angle (G) enhances control on descents. The low, optimized bottom bracket height (H) boosts stability, and the long wheelbase (K) ensures smooth tracking on loose surfaces.
Designed for all-day rides, the frame features generous tire clearance (I) for wide gravel tires, internal routing for clean cable management, and multiple mounting points for racks, fenders, and bikepacking gear. Its robust construction and carbon layup are tuned to withstand the rigors of gravel riding, making it ideal for everything from weekend adventures to multi-day bikepacking trips. Lightweight yet durable, this frame is ready to take you further on every off-road journey.
