*Lockout is meant to be adjusted throughout the ride depending on terrain.
Note: Damping “clicks” are always counted counter-clockwise from fully closed (max damping).

Damping Tuning Guide

Rebound (how fast the suspension returns after compression)

  • Speed up rebound (fewer clicks, more open):
    • Suspension extends faster.
    • Useful on rough, chattery terrain to keep wheels glued to the ground.
    • Prevents the bike from feeling “stuck down” after multiple hits.
  • Slow down rebound (more clicks, more damping):
    • Suspension extends slower.
    • Adds stability on big drops/jumps so the bike doesn’t buck you forward.
    • Helps with traction in corners by keeping the suspension from pogo-ing.

Compression (how much force it takes to compress the suspension)

  • Low-Speed Compression (LSC):
    • Controls body movement like pedaling bob, brake dive, and rolling through berms.
    • Increase (more clicks, firmer): Better support when climbing or pumping.
    • Decrease (fewer clicks, softer): Smoother ride over small bumps/roots.
  • High-Speed Compression (HSC):
    • Engages on sudden, hard hits (rocks, drops, square edges).
    • Increase (firmer): More resistance to harsh bottom-outs.
    • Decrease (softer): Better absorption of sharp hits, more comfort.

Quick Trail-Side Rules of Thumb

  • Feeling harsh/losing grip on chatter → Open rebound or compression slightly.
  • Getting bucked forward on jumps/drops → Slow down rebound.
  • Bottoming out too easily → Add compression (start with HSC).
  • Bike feels harsh on small bumps → Back off LSC a few clicks.
