Warning!

*Seat post has strong compression spring. When it is in the compressed position, pulling the pin will cause post to expand rapidly into the “raised position.”

* Make sure to use the enclosed rubber boot to keep mud and water out. When storing for extended periods, keep in the up position.

Mounting instructions

  1. Remove existing post from the bike. Clean and check for deformations and burrs.

  3. Insert Descenderpost into bike. The post can be positioned with unit facing forward or backward.
  4. Install seat on the post and tighten slightly
  5. Position the seat height to desired height and tighten seat-clamp. Make sure you have inserted the post at least 3.0 inches into the seat tube on your bicycle so as not to damage post or bicycle frame.
