Specialized Future Shock 3.3 Hydraulic Suspension Cartridge

Specialized Future Shock 3.3 Hydraulic Suspension

Factory Replacement | 20mm Travel | Hydraulic Compression Adjust | 20023-8015

The Specialized Future Shock 3.3 is the most adjustable version of Specialized's Future Shock front suspension system, combining 20mm of travel, hydraulic damping, adjustable compression, and rider-specific spring tuning.

Positioned between the stem and head tube, Future Shock isolates the rider from road impacts and vibration while maintaining a rigid connection between the fork and front wheel. The 3.3 cartridge allows compression damping to be adjusted while riding, letting the rider choose a firmer setting for smooth terrain or a more open setting for rough pavement and mixed surfaces.
