These kits include a new wipers, nut seal, keys, lower bumper, as well as upper and lower bushings.   The kit also includes a small amount of Grease as required for the rebuild.  Use this kit if your post is getting worn, your wipers are torn/worn out, or if you have started to leak air from the main nut. 

The kit also includes a replacement urethane Air Cushion and Retaining Ring. It can be used to replace a metal air cushion (retired) or a worn urethane one.

This kit is ONLY for Fall Line seatposts with the v1 Collar Nut.  Use this kit only if you are replacing the v1 Collar Nut with the v2 Collar Nut (RECOMMENDED).  There are other kits available if your post has a v2 Collar Nut.

See the  Specs tab for a list of the Kit Contents. 


In order to rebuild a Fall Line seatpost with this Kit you will need a standard cassette spline tool like the Park FR-5 or similar (NOT INCLUDED):  


 The Cassette spline tool is NOT included.
