Derived from the multi-award-winning XXF, the Mono XXZ, until now reserved exclusively for our official teams, is now at the cutting edge of technology, with a completely new design and a host of new technical features, including 4 settings: compression and extension at low and high speeds, with new configurations designed to give the rider the best possible feeling.  Inside, it has been updated with technical solutions that optimise the fluidity of moving parts, improve the damping coefficient and increase stability at high temperatures, not forgetting the use of lightweight materials to reduce overall weight.  The Ø14mm stem increases fluidity and the Ø30mm piston reduces the mass of fluid in motion for a faster response to stresses. Particular attention has been paid to increasing the sensitivity and precision of settings.  XXZ is designed to reduce inertia and provide immediate control of suspension oscillations.
The aim is to provide the rider with greater driving precision and grip than ever before, as well as uniform tyre wear thanks to instant control of the forces at play. This gives the rider maximum support in bends, even at extreme lean angles, rapid changes of direction, maximum confidence in opening the throttle on all types of track, and perfect rear-end stability even under the most violent acceleration.

BITUBO XXZB1 Rear Shock Absorber (Manufacturer Ref: A0050XXZB1) — designed for demanding roadsters, this monoshock incorporates technical solutions developed in competition to provide precise suspension behavior on the road. Performance and adjustments are at the heart of the product: rod diameter Ø14 mm, piston diameter Ø30 mm, and DLC treatment on the rod to limit sticking and improve sensitivity in motion.

The XXZB1 offers a wide range of adjustments to fine-tune the behavior of the rear end according to your riding style and chassis geometry:

• Low-speed compression: 24 clicks
• High-speed compression: 20 clicks
• Rebound: 24 clicks
• High-speed rebound: 20 clicks
• Pneumatic preload: 10 mm = 10 clicks (optional rechargeable reservoir)
• Spacing: 8 mm

Main features: piston diameter 30 mm, rod diameter 14 mm. Available adjustments: rebound, double compression (low and high speed), preload, and height. The design reduces the mass of fluid in motion for a quicker response to demands and better sensitivity of adjustments.

Included in the box: specific model instructions and adjustment sheet. Possible accessory: quick-connect rechargeable reservoir for pneumatic preload (sold separately).
