Racing Monoshock with hydraulic preload
Introduced in 2008, under constant development, XXF is sits at the top of current technology
EVOLUTION of this shock has culminated in an overall weight decrease, using an aluminium body, which has always been a very important feature in racing for better handling response to the rider’s needs. In addition to new set-ups, even more race-ready, and a upgrade aimed at better performance and adjusting simplicity of the length and hydraulic spring preload adjustment.
INNOVATION is in the internals of the shock, with new technical solutions for improving the damping coefficient and increasing the stability at high temperature. The Ø14mm rod improves the sliding, while the Ø30mm piston reduces the moving fluid masses. These improvements have produced a reduction of inertial forces, and therefore an immediate control of the suspension oscillations.
Some particular attention is paid to increase sensitivity and precision of the adjustments, which are all positioned in the upper portion of the shock.
OBJECTIVE is to give the rider the precise control and maximum grip increase, as well as even tire wear thanks to the immediate force control. This ensures the best rider control in the curve even at extreme inclination angles, fast direction changes, maximum confidence under acceleration in all kinds of tracks and perfect stability of the rear, even under the hardest braking.
ADJUSTMENT VALVES KIT XXF shock absorbers can be easily and quickly modified thanks to the replacement of the XD compression valve and XS rebound valve. The supplied set-up is labelled on the shock body. Bitubo Racing department has created specific set-ups for several bikes developed with the world champion teams and their riders, now available to you, the enthusiast, with specific damping coefficients.
Bitubo supplies complete valve kits in single or double speed, provided with the relative graphs.
