Lightweight carbon frame with modern geometry
With the Horn, Spanish manufacturer Unno is launching a new cross-country race bike on the market that aims to impress with its lightweight carbon frame and innovative geometry. The frame consists of a mixture of high-strength and high-modulus carbon fibre material, which is intended to provide an optimum balance between stiffness and weight. With 110 millimetres of travel at the rear, the Horn is designed for use on demanding XC race tracks. Unno states that the frame should enable a particularly efficient transfer of power from the bottom bracket to the ground.
According to Unno, the geometry of the Horn was specially developed for modern cross-country requirements. It is designed to give the bike agile and controllable handling both uphill and downhill. The Horn is available in three frame sizes: S1, S2 and S3. In this way, Unno aims to offer an optimum fit for different body sizes from 155 to 195 cm.
Innovative frame details for more performance
To further optimise the handling, Unno has added some interesting details to the Horn frame. For example, a flex-stay design is used in which the chain stays are designed to be flexible without an additional joint. This is intended to save weight and at the same time increase the sensitivity of the rear triangle. The shock is semi-integrated into the frame, but remains easily accessible for maintenance work. An integrated chain guide with rubber coating is designed to protect the elegant carbon frame and at the same time ensure that the chain runs smoothly and safely.
The cables for the gears and brakes are routed in the frame for a tidy look. According to Unno, they can simply be pulled in from behind without having to dismantle the frame. The cables are also fully routed to prevent rattling noises. The entry of the shift cable on the rear derailleur is concealed so that no visible opening remains when using an electronic shifting system.
High-quality equipment for racing
Unno offers the horn in four different equipment variants: Factory FA, Factory SL, Pro and Race. The two Factory models are the top versions. They are equipped with the highest quality components from Rockshox, Sram and DT Swiss. The Factory FA version relies on the electronic suspension control Flight Attendant from Rockshox. On the Factory SL model, the suspension and seat post are purely mechanical instead, which reduces the total weight to just 9.6 kilograms according to the manufacturer.
Both Factory versions are equipped with the electronic XX SL Eagle AXS groupset from SRAM. It offers 12 gears with a gear range of 520 per cent. The crank is fitted with a 34-tooth chainring. Braking power is provided by Formula Cura X disc brakes with 160 millimetre rotors. The wheels are from DT Swiss from the XRC 1200 series. They are fitted with Schwalbe Rocket Ron tyres at the front and Thunder Burt tyres at the rear in 29 x 2.25 inch size.
Noble XC bike for ambitious riders
With the Horn, Unno is targeting ambitious cross-country riders who are looking for a light and efficient race bike that also cuts a fine figure on technical trails and, of course, in front of the ice cream parlour. The 110 millimetre suspension travel offers enough reserves for demanding trails. At the same time, the geometry should enable agile handling. The standard Vario seat post emphasises the versatile character of the bike. It allows the saddle to be lowered for descents, giving you more freedom of movement.
Unno states that the Horn's suspension is designed for balanced response behaviour. The characteristic curve should be firm enough at the beginning of the suspension travel to minimise bobbing when pedalling. In the middle range, it becomes more progressive to provide enough support for tougher applications. The anti-squat value is 100 per cent, which should enable efficient pedalling without annoying compression. Unno aims to have created an XC bike that delivers good performance both in marathons and on technical courses.
