3. Suspension Setup – RIDE-4 Geometry and Sag Adjustment
The RIDE-4 system allows riders to fine-tune the bike’s geometry and suspension feel, adapting to different riding conditions.
RIDE-4 Positions & Effects:
🔹 Position 1 (Slackest) – Best for fast descents and aggressive riding.
🔹 Position 2 – Balanced setup for technical trails.
🔹 Position 3 – Increased pedaling efficiency while maintaining traction.
🔹 Position 4 (Steepest) – Optimized for climbing performance.
Sag Setup for Maximum Performance:
- Step 1: Wear full riding gear and mount the bike.
- Step 2: Bounce lightly to settle the suspension.
- Step 3: Measure sag using the O-ring or a sag meter.
-
Step 4: Adjust sag based on riding style:
- Technical Descents / Aggressive Riding: 28-33% sag
- All-Mountain / Trail Riding: 25-30% sag

4. Suspension Tuning – Rebound and Compression Adjustments
Rebound Tuning:
✔ Too Fast? The bike feels bouncy and unstable over rough terrain.
✔ Too Slow? The suspension packs down and doesn’t recover quickly.
✅ Pro Tip: Start with mid-range rebound settings, then fine-tune based on weight and terrain.
Compression Damping:
✔ High-Speed Compression (HSC): Controls fork and shock behavior on large impacts.
✔ Low-Speed Compression (LSC): Affects small bump sensitivity and pedaling efficiency.
Tuning Tip: Increase HSC for rough terrain and adjust LSC for better pedaling support.
