SID (Superlight Integrated Design)

  • Travel Options: 110mm and 120mm.
  • Air Spring: Larger, more tunable DebonAir+ air spring.
  • Upper Tubes: 35mm.

SID SL (Super Light)

  • Travel Options: Up to 100mm and 110mm.
  • Air Spring: Different design, not featuring DebonAir+.
  • Upper Tubes: 32mm, making it the lightest and most efficient fork.

Charger Race Day 2 Damper

  • Introduced a new efficient Pedal position alongside the standard Open and Lock.
  • Three damping options: Open, Pedal, and Lock, each with distinct oil flow paths.
  • Improved seals within the damper system to handle higher pressures.

Chassis Updates

  • SID’s chassis underwent updates, making the Ultimate model 70 grams lighter.
  • Crowns machined to remove unnecessary material.
  • Longer upper tubes to engage upper and lower bushings fully, reducing friction.
  • Increased bushing overlap to reduce side load and further decrease friction.

DebonAir+ Air Spring

  • Implemented in the SID lineup (not in SID SL).
  • Bigger air spring volume by extending the spring-side lower leg.
  • 50% increase in negative air spring chamber for softer initial travel.
  • 16% increase in positive chamber for better support in the middle of the travel.
  • Replaced rubber Top Out Bumper with a coil spring for reduced harshness.

Ride Feel and Performance

  • Achieved smoother and lighter performance simultaneously.
  • Redesigned 3P and 2P dampers for improved ride feel.
  • Significant tweaks and iterations for enhanced performance and durability.

Model Range

  • 2024 SID and SID SL forks are available in four different models: Ultimate, Select+, Select, and base-model.
  • Offered with either three-position (3P) or two-position (2P) damping.

DebonAir Airspring Upgrade

  • Progressive resistance: The increasing resistance as the spring compresses provides more predictability.
  • Fewer Bottom outs: Resistance increases as the coil compresses making the forks (or shock) less likely to bottom on a hard drop.
  • Improved rebound: Assists with bunny hopping obstacles or clearing doubles.
  • Reduced weight. Air shocks are typically half the weight of coil springs. Forks are also substantially lighter.
  • Easier setup: It is easy to add or remove air to adjust resistance. By comparison, coil springs would require a replacement spring.
  • Simple spring progression adjustment: It is simple to add or remove, bottomless tokens to adjust the progression of the fork. A range of replacement springs would be required on a coil fork to obtain the same adjustment.
