2. Suspension Setup – RIDE-4 Geometry & Sag Adjustment
The RIDE-4 system allows easy geometry and suspension tuning for different trail conditions and rider preferences.
RIDE-4 Positions & Effects:
🔹 Position 1 (Slackest) – Best for technical descents and aggressive riding.
🔹 Position 2 – Balanced for enduro racing and mixed terrain.
🔹 Position 3 – Improved pedaling efficiency while maintaining stability.
🔹 Position 4 (Steepest) – Ideal for trail riding and optimal climbing performance.
Sag Setup for Maximum Performance:
- Step 1: Wear full riding gear and mount the bike.
- Step 2: Bounce lightly to let the suspension settle.
- Step 3: Measure sag using the O-ring or a sag meter.
-
Step 4: Adjust air pressure based on riding style:
- Enduro/Technical Riding: 25-30% sag
- Trail/All-Mountain: 20-25% sag
- Firmest/Racing Feel: 15-20% sag

3. Suspension Tuning – Rebound & Compression Adjustments
Rebound Tuning:
✔ Too Fast? The bike feels bouncy and unstable.
✔ Too Slow? The suspension feels sluggish and doesn’t recover quickly.
✅ Pro Tip: Start at the midway rebound setting, then fine-tune based on weight and terrain.
Compression Damping:
✔ High-Speed Compression (HSC): Controls fork/shock response to big hits.
✔ Low-Speed Compression (LSC): Affects small bump compliance and pedal efficiency.
Tuning Tip: Increase HSC for aggressive riding, and adjust LSC for better support on climbs.
