Unno Horn Pro | Next-Gen XC Performance
The Unno Horn Pro (2026) is the "sweet spot" build of Unno's radical new cross-country platform. Breaking away from the brand's usual focus on long-travel enduro, the Horn is a dedicated XC racer that applies Unno’s "gravity DNA" to a sub-10kg package.
While the flagship "Factory" builds focus on ultimate weight savings, the Pro spec prioritises race-day reliability with the SRAM X0 Transmission and RockShox Flight Attendant electronic suspension.
The Horn Pro is built around a frame featuring a sophisticated blend of Toray T800 and T1100 carbon fibres. Unlike the previous dual-link Unno designs, the Horn utilizes a modern flex-stay single-pivot system to drop weight while maintaining a 100% anti-squat value for efficient pedalling. The shock is semi-integrated into the top tube, creating a striking, futuristic silhouette while remaining fully accessible for adjustments.
RockShox Flight Attendant: The Pro build is equipped with the automated Flight Attendant system. Sensors on the fork, shock, and crankset communicate wirelessly to adjust your suspension between Open, Pedal, and Lock positions in milliseconds, ensuring you are always in the most efficient mode without touching a remote.
Aggressive XC Geometry: With a slack 66-degree head angle and 435mm chainstays, the Horn handles like a down-country bike on technical descents but maintains the snappy, explosive acceleration of a purebred climber.
DEUX XC Cockpit: Features Unno’s proprietary DEUX integrated carbon bar and stem. At 760mm wide with a 60mm virtual stem length, it provides incredible steering precision and dampens high-frequency trail buzz.
Hidden Protection: The frame includes a discrete integrated rear mudguard, a minimalist chain guide, and an internal Acros Block-Lock headset to prevent the bars from over-rotating and damaging the frame during a crash.

SRAM X0 Eagle Transmission: The hangerless "T-Type" groupset provides the most robust wireless shifting available, specifically engineered to shift perfectly under the maximum pedalling loads of an XC sprint.
Zipp 1Zero HiTop Carbon Wheels: These rims are designed with a "compliant" layup to reduce rider fatigue and minimize the risk of pinch flats on rocky sections.
Massive Tyre Clearance: Despite being a lightweight racer, the frame has clearance for up to 2.6" tyres, allowing for high-volume setups on technical marathon courses.
Threaded BB: Uses a standard BSA 73mm threaded bottom bracket for easy maintenance and a creak-free ride in UK conditions.
