The pleasure of long-distance rides
The Granturismo SLR is a high-performance endurance road bike built for riders who demand both speed and comfort. Engineered for long-distance rides, it features specially designed endurance geometry and the advanced Actiflex 2.0 system—an updated rear micro-shock absorber originally introduced in 2017 with the Cento10 NDR. This combination ensures reduced postural fatigue while delivering exceptional ride quality, even on the most demanding routes.
Actiflex 2.0
The heart of Granturismo SLR is the Actiflex 2.0 vibration damping system that enables the rear wheel to obtain up to 5mm in vertical travel. The 2.0 is the updated version of Actiflex that was featured on Cento10 NDR, the winner of the 2017 Eurobike Award and of the prestigious Tour Magazin Reader's Award in 2018.
New design, higher efficiency
Actiflex 2.0 gives Granturismo SLR a smooth and comfortable ride. Torsional stiffness and responsiveness are guaranteed by numbers very close to those featured on other Wilier racing bikes, thanks to the bridge on the rear stays and the new positioning of Actiflex near where the seat tube and top tube intersect.
When redesigning Actiflex, one of the main goals was to achieve maximum frame integration, not just for aesthetic purposes but also to make it more functional. In its new position, Actiflex is protected from dirt, mud, sand, and rain, offering an ideal solution to allow the four bearings to work easily without having to worry about future maintenance. The double-screw locking system makes disassembling Actiflex 2.0 easy.

Racing comfort geometries
The frame's geometries play a fundamental role when it comes to endurance bikes. To guarantee the highest racing and comfort levels, different frame tube proportions must be taken into account. The position is slightly shorter (less reach compared to bikes with traditional racing geometries) and higher (greater stack in comparison to racing geometries).
This combination of reach and stack provides a more comfortable position without the need for spacers between the handlebar stem and the frame. How many times do cyclists ride pure racing bikes with centimetres of spacers on the head tube? With Granturismo SLR the bike will appear more harmonious, well-proportioned, and balanced while maintaining its racing character.

High end carbon
The carbon mix used for Granturismo SLR is HUS-MOD combined with Liquid Crystal Polymer, the special fiber incorporated in the carbon mesh that adds vertical elasticity while increasing torsional stiffness. This solution is also widely used in other top-range products such as Filante SLR and Wilier 0 SLR.
Two types of elastomer
The rear wheel travel is regulated by an elastomer made of viscoelastic material. In models featuring Shimano Dura Ace Di2 12V, Sram Red AXS and Campagnolo Super Record WRL setups, the elastomer is replaced with a 3D printed conformal lattice structure, a solution that reduces the overall weight of the frame by a further 20g.
Aerodynamics in the endurance world as well
Cycling long distances means spending long hours on the saddle. And, although Granturismo SLR doesn’t offer maximum competition performance, aerodynamics is still important, even in a bike of this type. Because when you’re spending hours on the saddle, even small details and enhancements can reduce fatigue.
So, we've added a number of characteristics derived from Filante SLR (our aerodynamic competition bike). In addition to the optimised tube section, we've considered the very wide fork crown, the integrated monocoque handlebar, and total cable integration.

Tire clearance
A wide fork crown improves aerodynamics and offers a generous wheel clearance. Wheels with tires up to a maximum width of 32 mm can be installed on Granturismo SLR, a perfect size for a modern bike like this one bred for endurance.
Removable derailleur support
The derailleur support is removable, just like on the Rave SLR. That’s because we believe that 1x assemblies will be used increasingly in the near future, even on road bikes not intended for use in competition.
For the 1x assembly, we've replaced the derailleur support with a flat plate to preserve the bike’s sleek look even without the front derailleur.

Carbon monocoque handlebar
Granturismo SLR mounts a monocoque handlebar that has a rounded ergonomic grip. The spacers, which are the same as those used on the Filante SLR, adapt it perfectly to the frame.
Granturismo SLR is compatible with all Wilier Triestina monocoque and modular handlebars.

Easy-fit spacers
The spacers between the frame head tube and the handlebar are made of a high-rigidity composite material, with a special cavity for routing the cables. They consist of two parts for quick assembly and disassembly, without interfering with the cables that run from the handlebar to the frame.

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.
