THE PLEASURE OF LONG-DISTANCE RIDES Granturismo SLR is a racing bike designed to bring out the utmost performance and comfort. With Granturismo SLR you will be able to travel long distances, minimizing postural stress thanks to the special endurance geometries and to the ACTIFLEX 2.0 system, a renewed version of the rear microshock 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.

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.

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.

AERODYNAMICS IN THE ENDURO 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.
