FOX's cartridge and spring kits use linear rate springs that maintain the same support throughout the fork's travel and won't dive when you brake or wallow when you corner. The cartridge's opposed-piston design creates a sealed system to prevent air from mixing into the oil, resulting in consistent damping control no matter how long you ride. The cartridge's spring-loaded upper piston moves easily to absorb even the smallest bumps, unlike gas-charged designs that can create internal friction and a harsh ride.
