TROUBLESHOOTING
ISSUE SYMPTOM
POTENTIAL CAUSE
SOLUTION
Action between positions is sticky / not getting
full travel to the Power position
Grease has migrated from the sliding surfaces /
general lack of grease / contamination
Unthread the seal head with a torque wrench and crow’s foot, clean and grease the
outside and inside surfaces of the inner tube. Removal of the seal head from the inner
tube should not be performed by the rider**. Applying lubricant to the surface of the
inner tube can sometimes temporarily resolve stickiness
Grease has migrated from the inner shaft /
general lack of grease / contamination
Remove the circlip at the base of the seatpost, then slide the outer tube up to the
saddle head assembly (see fig.1). Clean and grease the inner shaft*
Pressure bleeds through the seal over time
Increase air pressure to the desired setting if pressure is below 55 PSI / 3.8 BAR*
Riding in cold weather (below 32°F / 0°C)
Increase the air pressure in 10 PSI increments, without exceeding 100 PSI / 6.9 BAR*
Seat collar torque too high
Inspect the torque spec or QR lever load and adjust if necessary*
Seatpost slips in the seat tube
Not enough friction between the seatpost and
seat tube
Verify the torque applied to the seat collar bolt, make sure it is torqued to the
manufacturer’s specification, and does not exceed 90 in-lbf / 10.2 Nm. If necessary,
apply friction paste to the seatpost/seat tube interface***
Post does not move when the lever is activated
Cable and housing friction
Inspect the cable ferrules at both ends of the housing to make sure they’re correctly
seated. If necessary, lubricate or replace the cable and cable housing*
Too little cable tension
Increase tension by turning the barrel adjuster counter-clockwise (see fig.2, item 2)*
Post moves without activating the lever
Cable and housing friction
Inspect the cable ferrules at both ends of the housing to make sure they’re correctly
seated. If necessary, lubricate or replace the cable and cable housing*
Too much cable tension
Reduce tension by turning the barrel adjuster clockwise (see fig.2, item 2)*
Incorrect housing positioning / insufficient
housing length (due to raising the seatpost)
Slide the housing back and forth slightly to make sure it’s seated properly in both
ends. If the housing is too short for the housing to seat properly at both ends without
binding when the handlebar is rotated, the cable and housing will have to be replaced
with a longer housing and cable
Slow/No return action 2-3 days after setting the
air pressure
Air leakage due to main seal damage
Replace or service the lower seal assembly**
Post not extending upon first lever activation
after being left compressed for a period of time
Grease has migrated from the sliding surfaces /
general lack of grease / contamination
Unthread the seal head with a torque wrench and crow’s foot, clean and grease the
outside and inside surfaces of the inner tube. Removal of the seal head from the inner
tube should not be performed by the rider**. Applying lubricant to the surface of the
inner tube can sometimes temporarily resolve stickiness
Grease has migrated from the inner shaft /
general lack of grease / contamination
Remove the circlip at the base of the seatpost, then slide the outer tube up to the
saddle head assembly (see fig.1). Clean and grease the inner shaft*
* This service can be performed by the rider.
** CAUTION: To preserve your warranty, these services/procedures must be performed by an Authorized Specialized Retailer. Any damage incurred while personally servicing your
seatpost is not covered by our Limited Warranty.
*** If the seat collar is torqued to specification and the seatpost slips in the frame, this may be the result of a fit/compatibility issue. Please consult your Authorized Specialized Retailer for inspection.
