2. Suspension Setup – Geometry and Sag Adjustment

The Slayer’s adjustable chainstay length allows you to customize handling for different riding styles.

Chainstay Adjustment and Effects:

🔹 Short Setting (434mm) – Faster handling for jumps and tight technical trails.
🔹 Long Setting (447mm) – Added stability for steep, high-speed descents.

Sag Setup for Maximum Performance:

  1. Step 1: Wear full riding gear and get on the bike.
  2. Step 2: Bounce lightly to settle the suspension.
  3. Step 3: Measure sag using the O-ring or a sag meter.
  4. Step 4: Adjust air pressure according to recommended settings:
    • Freeride / Bike Park: 28-33% sag
    • Enduro / Technical Riding: 25-30% sag
    • More Pedal Efficiency: 20-25% sag

3. Suspension Tuning – Rebound and Compression Adjustments

Rebound Tuning:

Too Fast? The bike feels bouncy and unstable on landings.
Too Slow? The suspension does not recover quickly, reducing control.

Pro Tip: Start at mid-range rebound settings, then fine-tune based on terrain and weight.

Compression Damping:

High-Speed Compression (HSC): Controls fork and shock behavior on big drops and jumps.
Low-Speed Compression (LSC): Affects small bump sensitivity and pedaling efficiency.

Tuning Tip: Increase HSC for high-speed rough terrain, and adjust LSC for better support on climbs.

Shimano XTR 12-Speed Drivetrain:

  • Ultra-smooth shifting and lightweight performance for aggressive riders.
  • Keep the chain lubed and check for wear every 500km.
  • Adjust derailleur tension for optimal shifting performance.

Brakes – Shimano XTR 4-Piston Hydraulic Disc Brakes:

Check brake pads for wear every 3 months.
