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.
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 Magazine Reader's Award in 2018. If on the vertical plane?? 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 to 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. The rear wheel travel is regulated by an elastomer made of viscoelastic material. In models featuring
Dura-Ace Di2 12V, Campagnolo Super Record EPS and Sram Red AXS 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.
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).
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.
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 optimized tube section, we've considered the very wide fork
crown, the integrated monocoque handlebar, and total cable integration.
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.
On Granturismo SLR, we've included the monocoque handlebar, which we usually install on Wilier 0 SLR, our flagship climbing bike. The 0 Bar has a rounded ergonomic grip that’s more comfortable
than the one on our aero Filante Bar. The spacers, which are the same as those used on the Filante SLR, adapt it perfectly to the frame. And don’t forget that the 0 Bar monocoque handlebar houses and routes the brake and derailleur cables inside the frame, protecting them from air friction and giving the Granturismo SLR the clean and pure lines that typify Wilier Triestina’s high-end products. Granturismo SLR is also compatible
with all Wilier Triestina monocoque and modular handlebars.
The derailleur support is removable, just like on 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
