TROUBLESHOOTING CONDITION
ADJUSTMENT SOLUTION
Bike wallows through turns.
Feels loose or vague after bumps.
Wheel tends to “pogo” after passing over a bump. This is noticeable
by watching the bike continue to bounce as it travels over multiple
bumps.

Increase rebound damping.
Wheel responds to bump, but doesn’t return to ground quickly after
bumps. This is more pronounced over a series of bumps and is
often referred to as “packing down.”
bumps. This is more pronounced over a series of bumps and is

Reduce rebound damping.
The bike bottoms out or dips while cornering.
Bike has excessive brake dive.
Bike has excessive brake dive.
Increase compression damping.
Harsh ride particularly over washboard surfaces.
Bumps kick through handlebars or seat.
Suspension seems not to respond to bumps. This is evidenced by
tire chattering (a movement with short stroke and high frequency)
through corners or by jolting the rider over rough roads.

Decrease the compression damping. If the problem
persists, decrease rebound damping for a faster
rebound rate. Less spring preload may also help.

TROUBLESHOOTING CONDITION
ADJUSTMENT SOLUTION
Not absorbing bumps.
A good suspension is a balance between damping and
track condition. Finding this balance requires exploring
all possible compression settings.
