THE NEW SUSPENSION SYSTEM
The URTA MAX features a new single-axle damping system. The compression ratio has been optimized 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 pedaling is required; and a final phase, that is more progressive, to avoid the suspension reaching the end of its stroke.
FRAME
The two triangles that form the Urta Max SLR frame are made of HUS-MOD high-module carbon fiber, the same used for all top-range Wilier products. Maximum stiffness only where necessary.
The front triangle completely integrates the cables within the frame, but unlike earlier models - where tubes and sheaths passed through holes made in the carbon fiber - 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 fibers.
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.
GEOMETRIES
The Urta Max geometries have been designed and optimized 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 centers) is greater than the previous Urta model. All this provides the rider with a greater sense of riding safety and aggressiveness in push position.
TELESCOPIC SEATPOST AS STANDARD
The Urta Max SLR leaves the Rossano Veneto factory with a 31.6 mm telescopic seatpost. Each size has a telescopic seatpost with dedicated travel: 100 mm travel for sizes S and M; 125 mm travel for sizes L and XL.
DESIGNED FOR MORE MODERN TRANSMISSIONS
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.
MAXIMUM FRAME PROTECTION
To protect the rear triangle and its bearings, we have designed a special rubber cover which, when installed in the area where the frame triangles meet, avoids mud, dirt and debris affecting the reliability and life of the frame in the long term.
TIRE CLEARANCE
The rear triangle has a 70 mm clearance point for mounting today's most modern off-road tires up to 2.4” ideal for any type of cross-country road.
URTA MAX BAR
And finally, for the carbon module, there is the new Urta Max Bar monocoque carbon handlebar.
The handlebar is perfectly integrated with the frame – as is the case of road products - thanks to special dedicated spacers. The comfort level is kept high thanks to the material used: the HUS-MOD high-module carbon with its exceptional ability to vertically absorb all the micro-vibrations generated by riding on rough terrains.
The particular negative inclination of the handlebar stem (- 27°) guarantees the rider a gathered position that will enable more powerful pedaling during the push phase, in technical uphill climbing and when relaunching.
