THE EPICA CARTRIDGE HAS BEEN DESIGNED TO PROVIDE THE BEST PERFORMANCE AND COMFORT BY PROVIDING MAXIMUM TUNABILITY

Our new EPICA Cartridge System combines years of experience, testing, and development into a single, comprehensive project. The primary objective of this project was to develop a highly tunable cartridge that enables riders to fine-tune their forks in ways previously impossible. Below is a breakdown of the critical features of this innovative design.

External adjustments:

• Compression damping – 60 clicks of sensitive adjustment– Adjustment at the top of the cartridge.
• Rebound damping – 50 clicks of sensitive adjustment– Located at fork bottom.
• External spring preload adjustment – 0 to 15mm– Easily adjusted with a 16mm socket at the fork bottom.

Innovative Features:

• Bladder System
  • Our bladder system prevents performance loss compared to standard internal spring systems (due to hydraulic support decay).
  • Internal oil compensation with increased volume is needed for a better high-speed response.
  • Ability to tune bladder pressures via the side bleed spring.
• EPICA cartridge incorporates Lainer’s Progressive Damping System (PDS) for increased hydraulic damping at the end stroke.
  • The PDS system has up to 12 adjustments for the end stroke stiffness.
• High-speed compression piston is reversible in an extensive range of settings.

Technical Specs:

• Machined from premium 7075 and 6060 alloys and hard anodized.
• Reversible High-Speed compression piston – outer diameter = 38 mm.
  • Side A (Flat valve surface) – 34mm OD shims for motocross and enduro.
  • Side B (Convex valve surface) – 32mm OD shims for supercross.
• Option to configure Low-Speed Valve (LSV) on compression base valve.
• Cartridge rod diameter = 14 mm (for an increased oil flow).
• Rebound piston diameter = 25mm for better hydraulic control.
• Compression high/low-speed shims ID 12 mm.
• Maximum travel = 310 mm.
• Maximum shim diameter for Mid-Valve By-pass = 21 mm.
• Ability to set Mid-Valve float clearance with the stack shims.
• Mid-Valve/By-pass floating shim ID = 6 mm (for a soft response at high speed on the braking bumps).
• Rebound shims ID = 6 mm (uses triangular mid-valve shims to avoid oil turbulence on compression).
• Low friction NBR bottom seal.
• Ability to extend the cartridge through the nylon washers.
