Max improvement, Max performance, Max fun!
This new MTB with 120mm travel has been designed with the aim of providing the WilierPirelli Factory Team a modern and versatile race bike featuring: a high-performancesuspension system, precise handling response and safety.
From the very first moment, the new Urta Max SLR will make you feel like you are on abike that is ideal for competitions but also fun on the most demanding trails.

THE NEW SUSPENSION SYSTEMThe 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 morereactive 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 SLRframe are made of HUS-MOD high-module
carbon fibre, the same used for all top range
Wilier products. Maximum stiffness only wherenecessary.
The front triangle completely integrates thecables within frame, but unlike earlier models- where tubes and sheaths passed throughholes made in the carbon fibre - on the Urta
Max the brake, derailleur and dropper tubes
pass through the headset, similarly to roadbikes. This solution provides the bike with anextremely 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 thecarbon fibres.
The rear triangle of the Urta Max is designedwith a single-pivot point. The new conrod(stiffened compared to previous versions) is
designed to give the frame a maximum travel
efficiency of 120mm.

WILIER.COM# L OV E M Y W I L I E RGEOMETRIESThe 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 aminimum, extending the reach and keeping
the bottom bracket lower. It is a solution thatallows the rider to stay gathered on the bike, aposition 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, theresulting wheelbase (i.e. the distance between
the front and rear wheel centres) is greaterthan 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 Venetofactory with a 31.6 mm telescopic seatpost.
Each size has a telescopic seatpost withdedicated travel: 100 mm travel for sizes S andM; 125 mm travel for sizes L and XL.

DESIGNED FOR MORE MODERN TRANSMISSIONSOFFROAD COLLECTIONThe Urta Max SLR has been designed toaccommodate 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, wehave 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 inthe long term.

TYRE CLEARANCE
The rear triangle has a 70 mm clearance point
for mounting today’s most modern off-roadtyres up to 2.4” ideal for any type of crosscountry road.

5COLLECTION
OFFROADAnd finally, for the carbon module there is thenew Urta Max Bar monocoque carbon handlebar.
The handlebar is perfectly integrated with theframe – 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 themicro-vibrations generated by riding on roughterrains. The particular negative inclinationof the handlebar stem (- 27°) guarantees
the rider a gathered position that will enable
more powerful pedalling during the pushphase, in technical uphill climbing and whenrelaunching.
