Bitubo Front Shock Absorber

The pressurized EBH cartridge incorporates a range of innovative systems, such as the well-known FPS, EC, and LC, as well as the new Overpressure Control System (OPC). These systems are the result of extensive development work by our research and development department in collaboration with some of the top teams that have competed in World SBK, BSB, IDM, and CIV. All adjustments--spring preload, rebound, and compression--are located on the upper cap and are separate, simple, and intuitive in both cartridges. The high damping coefficient at very low speeds controls excessive front-end dive from the very first moments of braking. Also available in the EBH59 version with an extended wheelbase!

TECHNICAL FEATURES

• Hydraulic control with FPS system (bitubo patent)
• Ø27 mm Ergal piston
• Ø 10 mm pump rod with a friction-reducing surface coating
• Mechanical bottom-out with polyurethane buffer in NBR
• Cr-Si steel springs with heat treatment, setting process, and final shot peening
• Upper fork crown with integrated spring preload adjustment
• Independent compression and rebound damping adjustment
• Coaxial compensation chamber (Bitubo patent)
• Ergal cartridge body with a friction-reducing surface coating
• Hydraulic lubrication separate from sliding lubrication
• Pressurization Force Control System

LC: This product features a high proportion of special lightweight alloys and weight-optimized details, with the goal of achieving maximum lightness.

FPS: Full Pressure System demonstrates the highest efficiency and practicality of this patented system. This innovative damping system provides immediate damping while preventing cavitation of the internal fluid. The system is pressurized with low-pressure gas. The cartridges are asymmetrical: one controls the compression stage, the other the rebound stage. With two opposing chambers at both ends, it is possible to generate high damping force even at very low speeds.

INCLUDED IN THE PACKAGE: Installation instructions with recommended oil viscosity and level, based on the experience and data from our R&D team, adjustment and installation tools, and Fuchs-Silkolene oil for smooth operation. The package includes 2 additional replacement springs with different stiffness rates for various setups, to ensure optimal control at the highest performance levels.

POSSIBLE ACCESSORIES: Fork steerer tube adjustment cap
