The Urta Max features a new single-axle damping system. The compression ratio has been optimised to be extremely effective on any terrain type.
The Rock Shox and Fox rear shock absorbers with 45mm travel that are mounted as standard have compression curves specifically tailored to work in symbiosis with the leverage ratio chosen in the design stage.
There are three operating phases: a regressive phase (stiffer and more sustained); a more reactive and sensitive phase, when maximum efficiency during pedalling is required; and a final phase, that is more progressive, to avoid the suspension reaching the end of its stroke.
The two triangles that form the Urta Max SLR frame are made of HUS-MOD high-module carbon fibre, the same used for all top range Wilier products. Maximum stiffness only where necessary.
The front triangle completely integrates the cables within frame, but unlike earlier models - where tubes and sheaths passed through holes made in the carbon fibre - on the Urta Max the brake, derailleur and dropper tubes pass through the headset, similarly to road bikes. This solution provides the bike with an extremely clean and elegant look and, not least, it improves the overall stiffness in the headset area as the absence of holes guarantees continuous modularity and directionality of the carbon fibres.
The rear triangle of the Urta Max is designed with a single-pivot point. The new conrod (stiffened compared to previous versions) is designed to give the frame a maximum travel efficiency of 120mm.
The Urta Max SLR has been designed to accommodate the more modern transmissions currently on the market.
It can mount a front crown up to 38 teeth and the standard issue UDH dropout is also compatible with the new Sram Eagle Transmission assemblies.
The Urta Max geometries have been designed and optimised to mount a 120mm travel fork, with the aim of keeping the rider in racing position, i.e. dropped and gathered.
To do this, we have reduced the stack to a minimum, extending the reach and keeping the bottom bracket lower. It is a solution that allows the rider to stay gathered on the bike, a position that provides better performance.
In detail, for size M the stack measures 598 mm and the reach 443 mm, while the steering angle is more open with 67.5° and the seat tube is at a vertical angle of 75°.
With these values, the resulting wheelbase (i.e. the distance between the front and rear wheel centres) is greater than the previous Urta model. All this provides the rider with a greater sense of riding safety and aggressiveness in push position. To do this, we have reduced the stack to a minimum, extending the reach and keeping the bottom bracket lower. It is a solution that allows the rider to stay gathered on the bike, a position that provides better performance.
