U1 Black - Matt
Break up the monotony
URTA SLR is at the height of Wilier Triestina's evolution in the mountain bike sector. A top-tier bike made to provide a more technical and leading-edge cross country cycling experience. The frame has been designed to reach extremely high levels of traction and stability.
Thanks to its reliability and efficiency, it is the best solution for those who strive for top performance on XCO/XCM courses.

Racing geometries
URTA SLR geometries revamp the off-road riding style of Wilier Triestina high-end products. A shorter triangle combined with a 69° steering angle make it compact, fast and balanced, thus improving performance both up the steepest climbs and down the most technical descents.
Designed to obtain better traction as well as excellent progressive response, URTA SLR also offers an impressive stiffness-to-weight ratio to ensure rapid accelerations and better responsiveness to sudden changes of direction.

Integrated shock absorber
URTA SLR has been designed for 190x45 rear shock absorbers with 100 mm progressive travel. For optimum kinematic performance, the choice has fallen upon the Fox Factory DPS FLOAT 190x45 whose optimised compression curves make it possible to work in perfect synergy with the frame. In addition to improving the clean look of the URTA SLR, link integration increases the torsional stiffness of the rear triangle.
Urta Bar integrated monocoque handlebar
Like with all other top-end racing bikes, URTA SLR also features a lightweight carbon fibre monocoque handlebar. It is a solution that treats the frame/handlebar system as a single highly integrated module, making it also possible to cut down the total weight of the bike. The carbon fibre handlebar also allows better vibration absorption, consequently reducing the physical wear caused by very demanding XCO/XCM courses.
Double bottle holder
URTA SLR is equipped by design with a double bottle holder. It is a necessary choice to limit the number of water stops the rider makes mid-race or during longer and more intense training.
Improved stiffness
The triangle has been designed using active swing arm technology, a solution that most efficiently combines vertical flexibility and in-plane torsional stiffness. This allows for even greater shock absorption as well as a more rapid and efficient response of URTA SLR to the power delivered by the rider in any situation. Furthermore, the higher pivot point and the shock absorber integration system add further stiffness to the rear triangle.
Monocoque carbon fibre
URTA SLR is made with HUS-MOD carbon fibre, the same type used for Verticale SLR and Filante SLR. The perfect stiffness and the prompt reactivity of URTA SLR are features that derive from the know-how that Wilier Triestina has gained over the years by working in close contact with professionals of the World Tour circuit and Wilier-Pirelli Factory Team.
Flat mount brakes
The brake callipers mounted on URTA SLR are standard flat-mount, the same as the ones used on racing bikes. Flat-mount brakes guarantee the same braking power as the traditional post-mount brakes for cross country cycling. The absence of the typical post-mount bridge provides the rear chain stays with more balanced flexion to the left and to the right.
100mm suspension fork
URTA SLR mounts FOX 34 STEP-CAST FACTORY KASHIMA forks, top range products with 100 mm travel. This solution makes it possible to reduce the overall weight of the bicycle because the frame is optimised to ensure maximum performance of the 100 mm fork. Locking and unlocking can be adjusted using the remote control installed on the handlebar.
UDH™ dropout
URTA SLR mounts a Universal Derailleur Hanger (UDH) that optimises operation of the Sram gear shifters but is also compatible with any next-gen derailleur. Use of the UDH dropout offers a further integrated safety function that allows the gear shifter, in the event of an accident, to rotate without breaking.
Integrated wiring
All gear shifter, brake and shock absorber wiring is integrated within the frame. It is also designed to integrate the wiring for a telescopic seatpost, when present. In addition to maintaining the clean and elegant look of the bike's lines, integrated wiring also provides additional and more adequate protection for the devices.
12-speed gear shifter
The gear range provided by the 12-speed Shimano and Sram single-crown gear shifters (510% gear range with Shimano 10-51 – Sram 10-52 cassettes) make it possible to face any incline and any race terrain, regardless of the length or ruggedness of the course.
Standard silicon chainstay protector and chain guide
The standard silicon chainstay is designed to dampen noises and absorb impact caused by the chain hitting the stay. In addition to providing great protection against scratches and impact, the chainstay protector is made to integrate seamlessly with the clean look of URTA SLR.
The chain guide comes as standard. Its purpose is to prevent the chain from falling on bumpy terrains and is indispensable on top-range single-crown MTBs. Like the chainstay protector, it has been devised to integrate perfectly with the overall design of URTA SLR.

Improve your riding position with accu-fit
Correct positioning in the saddle is one of the most essential issues for cyclists, especially for competitors and long-distance cyclists. While with steel bikes, it was relatively easy to measure the length of the tubes, as the years passed, and with the introduction of sloping top tubes, defining measurements has become increasingly complex. So, in addition to the classic values of height, length and angles, we now consider reach & stack data and horizontal and vertical distance values between the centre of the bottom bracket and the centre of the upper part of the head tube.
But modern bicycles have made measurement even more complex, since they are complete and complex systems based on the combination of the frame, handlebar spacers and monocoque handlebars. When buying a bike, it is essential to know the size of every bike element based on your body size and shape. As manufacturers of frames and monocoque handlebars, we have added a new value to the measurement of the frame which combines the length of the head tube and the dimensions of the monocoque handlebar.
This coordinate, called ACCU-FIT, determines the distance between the bottom bracket's center and the handlebar's center. It is clear that for every model there are as many coordinates as frame sizes multiplied by the number of handlebar sizes and the configuration of spacers.
