Does your bike currently have a dropper? If so, is the cable running through the inside of the frame (internal routing) or is it secured along the outside of your frame (external)? What’s the age of your bike? Internal routing started around 2014 on high end mountain bikes and became more common on bikes after 2016 - if your bike is older than that it most likely is only compatible with external routing. 

Got a newer bike? Look for internal cable ports that would send the cable housing up the seat tube to the bottom of the post. Common spots for a port are towards the bottom of the seat tube, near the bottom bracket or possibly up near the head tube where your other internally routed cables enter.

As riding frequency and conditions vary, we do not have a strict service interval. Instead, we recommend servicing your post if it starts to feel sticky/slows down. When it does come down to service it is a quick and easy, at home process. Check out our service video's here.
