NOTI CE
Do not scratch the inner shaft with the wrench as this is a critical
sealing surface. Surface scratches can cause leaks and reduce
performance.
Do not compress the inner shaft into the upper post and IFP tube until
the seatpost is completely reassembled. If the inner shaft does get
pressed into the IFP tube, remove the seal head and repeat
steps 1 and 2.
