Unno Horn carbon XC Frameset
2026 Unno Horn Carbon XC Frameset
The 2026 Unno Horn Frameset represents the cutting-edge of modern cross-country and down-country performance. Engineered in Barcelona, this frameset moves away from old-school, twitchy XC geometry, injecting Unno’s legendary gravity DNA into a lightweight, high-modulus racing platform. Featuring 110mm of rear travel delivered through a weight-saving flex-stay suspension system, the Horn is built to climb aggressively while remaining exceptionally stable on World Cup-level descents.
The Unno Horn frameset is a masterclass in premium carbon engineering, utilizing a precise blend of UHM T800 and T1100 carbon fibre. This hand-assembled monocoque construction achieves a stunning raw PRO Twill carbon weave finish while providing the radical lateral stiffness needed for instantaneous acceleration out of corners. The frame is optimized around a 120mm fork paired with its native 110mm of rear wheel travel, using a modern flex-stay rear triangle that completely eliminates heavy bearings and hardware at the rear dropouts.
Unno has packed the Horn with clever frame integration. The rear shock is semi-hidden beneath a sculpted, split top tube, protecting it from flying debris while keeping the air valve and rebound dials fully accessible. Cable management is entirely internal, featuring pre-molded internal routing paths that let mechanics slide hoses straight through from the rear stay to the head tube without rattling. Equipped with an integrated chain guide, rubber molded chainstay protection, and an internal Block-Lock headset to prevent the handlebars from striking the top tube during a crash, this frameset is the ultimate blank canvas for an elite off-the-shelf build.'

EVO OPINION:
Unlike old-school cross-country frames that rely on firm shock lockouts to feel fast, Unno has designed the Horn with a highly efficient 100% anti-squat value at sag. This means the frame naturally resists bobbing under pedalling forces even when the shock is run wide open.
The suspension layout features a firm initial leverage ratio to keep the bike sitting high and supportive during hard, out-of-the-saddle climbing efforts. As you push deeper into its 110mm of travel, the suspension curve smoothly ramps up toward the end of the stroke. This prevents the harsh, abrupt bottom-outs common on lightweight flex-stay frames when casing jumps or landing heavy drops on technical modern race tracks.
