Replacement cartridge for SWR model telescopic seatpost.
To check whether the telescopic seat post is of the SWR or SW model, simply check whether or not there is a valve for inflating the seat post under the saddle attachment.
If the valve is present, it is the SWR model.
If in doubt, contact us through the chat, we will reply as soon as possible.
Porduct is ok, but no installation manual… had to figure it out how to replace it. Not that hard but a manual or a link to video tutorial would be cool
