All FAST shocks and cartridges are custom-built to your exact specifications. Each unit is hand-assembled and tuned to suit your bike and riding style.
Lead time is typically up to 4 weeks from order to delivery.
After placing your order, you’ll receive a setup questionnaire to confirm your bike details, weight, and preferences — ensuring you get the perfect setup for you and your bike.
The Ultimate Fork Upgrade
The FAST SC5 Cartridge is designed to transform your fork’s performance, giving you more control, grip, and confidence on any terrain.
Developed from FAST’s race-proven technology, the SC5 features three independent compression circuits — low-, mid-, and high-speed — for precise control across every type of hit.
Low-speed compression improves comfort and support on small bumps.
Mid-speed compression controls diving and bike balance under braking and cornering.
High-speed compression smooths out big impacts and rough ground for a more composed ride.
The result is a fork that feels planted, predictable, and consistent, no matter how demanding the trail.
The SC5 also offers externally adjustable low-speed rebound, while the high-speed rebound is internally tuned to your preferences. Each cartridge is hand-built to order and custom-valved for your riding style, ensuring factory-level performance tailored to you.
Constructed from aerospace-grade 7075-T6 aluminium, the SC5 is a fully sealed system with an internal floating piston (IFP) for consistent damping and long-term reliability.
