Page 5: Set Sag
Set Sag Suspension sag can be used to set the proper suspension spring rate. Sag is the amount of travel, measured as a percentage of full travel, that the suspension compresses when the rider, including gear, is on the bicycle in the normal riding position. -

Page 17: Rebound Damping
Rebound Damping Rebound damping controls suspension fork extension/return speed which affects traction and control. • Optimal rebound damping allows the fork to extend at a controlled speed and maintain traction and control. • Rebound that is too fast allows the fork to extend too quickly which causes the wheel to bounce off of objects and the ground resulting in a 'pogo' effect. -
Page 18: Rebound - Optimal
Rebound - Optimal The fork rebounds at a controlled speed and the wheel maintains contact with the ground. The fork crown, handlebars, and rider are more level with the ground over each bump. Suspension movement is predictable and controlled. Adjustment - No adjustment is needed. -
Page 19: Rebound - Too Fast
Rebound - Too Fast The fork rebounds too quickly causing a 'pogo' effect where the wheel bounces off of the terrain unpredictably. Traction and control are decreased. The fork crown and handlebars are forced upward after the wheel bounces off of the ground. Rider weight may shift upward and back uncontrollably. -
Page 20: Rebound - Too Slow
Rebound - Too Slow The fork does not extend quickly enough after absorbing a bump. The fork stays compressed through successive bumps, reducing travel and increasing impact firmness. Available travel, traction and control are decreased. The fork stays in a compressed state which puts the crown and handlebars in a lowered position. Rider weight may shift forward. -
Page 21: Low Speed Compression Damping
Low Speed Compression Damping Low speed compression (LSC) damping adjustment controls compression stroke speed, or the rate at which the fork compresses, during slow compression stroke scenarios. LSC affects bump absorption and efficiency during rider weight shifts, transitions, cornering, more gradual bump impacts, and braking. -
Page 22: Rolling Terrain
Rolling Terrain Low Speed Compression Damping - Open / Too Soft Adjustment: The fork compresses low into the compression stroke through the low point of the terrain. Suspension travel is To improve efficiency on used quickly, the rider's weight may shift forward, and bicycle momentum may be reduced. rolling and smoother terrain, rotate the LSC or Compression adjuster knob clockwise to... -

Bumps Low Speed Compression Damping - Soft to Mid Adjustment: At bump impact, the fork compresses quickly and freely, and the bump is absorbed. Traction is maintained. To increase small bump sensitivity rotate the LSC or Compression adjuster knob The fork reacts quickly to the impact. The crown and handlebar rise slightly as the bump is absorbed. counter-clockwise to decrease compression damping and firmness, and increase... -
Page 24: High Speed Compression Damping
High Speed Compression Damping High speed compression (HSC) damping adjustment controls compression stroke speed, or the rate at which the fork compresses, during quick compression scenarios. HSC affects bump impact absorption and efficiency over large and square edge bumps, and down drops. Bump size and shape, as well as riding speed, can affect compression stroke speed. -

Page 28: Compliance And Blow-Off
Compliance and Blow-Off Lockout mode features key rider benefits when activated - Compliance and Blow-Off. Motion Control™ and Turnkey™ (A) Compliance - A fixed amount of suspension fork movement that improves traction and control over small bumps while in the lock position. When locked out a small amount of compliance prevents the wheel from bouncing off of impacts which helps maintain traction. -
