SDG Tellis Dropper Seatpost tear down and rebuild.
In this video we take the SDG Tellis seatpost that has been living on my hardtail for about 2 years now and give it a rebuild. New seals and bushings to keep it moving smooth and wobble free.
The design used is similar to a few others on the market. This guide may help you be able to rebuild your post if it is a sealed cartridge design like this one is.
