Kolo PINARELLO XC full GX AXS

This frame delivers extreme stiffness in the rear triangle and bottom bracket, thanks to an oversized bearing and pivot point for the rear triangle.

The rear suspension kinematics take the integration of flex stays into account to maximize energy transfer while pedalling, deliver optimal compression/rebound on technical descents, and enable maximal rider control.

Friction at each pivot point has also been minimized by utilizing a mixed bearings/bushing system. Bushings have been incorporated as they are durable enough to absorb the high impact and low rotational forces placed upon them, whereas bearings have been integrated where the opposite forces apply (low impact/high rotation). This results in reduced energy dispersion, increased reactivity of the rear end, and increased durability of the system.

Anti-rise and anti-squat values have also been studied to create a bike which excels on both the steepest climbs and most technical descents.

The rear triangle utilizes a patented asymmetric design with the left-hand side being reinforced, allowing the bike to counterbalance the higher forces being applied on the opposite side of the drivetrain. This results in more balanced energy transfer, improved speed and traction.

Asymmetry has also been maximized in other areas of the frame, with the chain and seat stays pushing this concept to the next level in order to withstand the powerful accelerations which are delivered in elite cross-country races.
