The pleasure of long-distance rides

Granturismo SLR is the racing bike designed to bring out the utmost performance and comfort. With Granturismo SLR you will be able to travel long distances, minimising postural stress thanks to the special endurance geometries and to the Actiflex 2.0 system, a renewed version of the rear micro-shock absorber developed in 2017 for the Cento10 NDR.

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.
