The carbon fiber lightest gravel frame redefines off-road agility, merging extreme lightness with rugged trail capability. Forged from ultra-high-modulus T1100 carbon fiber, it tips the scales at just ~1150g (frame only)-30% lighter than standard gravel frames-without sacrificing structural integrity.
Its optimized monocoque construction delivers stiff power transfer for climbs, while compliance-tuned seatstays absorb jarring gravel impacts. With max 700×47mm tire clearance, it grips loose terrain effortlessly, while aerodynamic truncated tube shapes cut drag on paved connectors.
Thru-axles and flat-mount disc brake compatibility boost stability, even on technical descents. Whether tackling backcountry gravel, forest trails, or mixed-terrain epics, this frame turns every pedal stroke into forward momentum-proving lightness and durability can coexist.
