Tuning Your Suspension: How to tell when you’re “over-damped”

Excessive Compression Damping:

When a mountain bike suspension system has excessive compression damping, it means that the shock absorber or fork is resisting compression too much, resulting in a stiff and less responsive ride. Here are ride qualities that riders may experience when there’s an overabundance of compression damping:

Harsh Ride: The bike feels harsh and rigid over rough or rocky terrain, transmitting more impact force to the rider.

Reduced Small Bump Compliance: Difficulty in absorbing smaller bumps or irregularities in the trail due to the suspension’s resistance to initial compression.

Limited Traction: Traction is compromised, especially on loose or slippery surfaces, as the suspension struggles to conform to the ground contours.

Loss of Sensitivity: Reduced sensitivity to trail feedback, making it challenging to read the terrain and adapt riding style accordingly.

Difficulty Maintaining Speed: It becomes harder to maintain speed over uneven terrain, as the suspension doesn’t absorb the terrain irregularities effectively, slowing down the rider.

Less Controlled Landings: During jumps or drops, the suspension feels less forgiving, making landings less controlled and potentially uncomfortable.

Limited Wheel Contact: The bike may have trouble maintaining consistent contact with the ground, affecting stability and control, particularly in corners and technical sections.

Reduced Comfort: The overall comfort of the ride is compromised, and riders may experience increased fatigue and discomfort, especially during long rides.

Difficulty Gaining Traction During Climbs: Insufficient suspension compliance can make it challenging to maintain traction while climbing, particularly on uneven or loose surfaces.

Excessive Rebound Effect: The rebound effect may be exaggerated, causing the bike to bounce or rebound excessively after compression, reducing stability and control.

Increased Impact Transfer to the Rider: Impact forces are transmitted more directly to the rider, causing discomfort and potentially leading to rider fatigue over prolonged periods.

Excessive Rebound Dampening: 

When a mountain bike suspension system has excessive rebound damping, it means that the shock absorber or fork is resisting extension too much, resulting in a slow return to its original position. Here are ride qualities that riders may experience when there’s an overabundance of rebound damping:

Harsh and Jarring Ride: The bike feels harsh and jarring, especially over small bumps and rough terrain, as the suspension is slow to extend and smoothen the ride.

Loss of Traction: Reduced traction on technical terrain due to delayed rebound, preventing the tires from quickly gripping the ground and affecting control.

Difficulty in Maintaining Speed: It becomes challenging to maintain speed and momentum, especially in sections where the suspension doesn’t extend quickly enough to absorb successive impacts.

Overly Stiff Feel: The suspension feels overly stiff and rigid, diminishing the bike’s ability to absorb impacts effectively and provide a smooth ride.

Reduced Cornering Performance: Difficulty in maintaining an optimal line through corners due to delayed rebound, impacting the bike’s ability to recover and set up for the next maneuver.

Uncomfortable Landings: Landings from jumps or drops can be uncomfortable and less controlled, as the suspension takes longer to extend, affecting stability and rider comfort.

Wheel Skipping or Bouncing: The wheels may bounce or skip over obstacles rather than conforming to the terrain, resulting in a less stable and controlled ride.

Loss of Suspension Sensitivity: Reduced sensitivity to changes in the trail, making it difficult for riders to read and adapt to the terrain, potentially affecting handling.

Increased Rider Fatigue: Excessive rebound damping can lead to increased rider fatigue over longer rides due to the constant impact transfer to the rider’s body.

Difficulty in Bunny Hopping or Maneuvering: Sluggish rebound can hinder the ability to perform quick maneuvers, bunny hops, or manual through obstacles efficiently.

To address excessive rebound damping, riders should experiment with rebound adjustment settings, gradually reducing the rebound damping to achieve a more balanced and responsive suspension. Seeking guidance from a professional or consulting the suspension manufacturer’s recommendations can also help riders fine-tune their suspension for an optimal riding experience.
