I know that my bike has a 25.4 mm diameter seat post. So can I purchase any old 25.4 mm diameter seat post from eBay and expect it work with my existing bike seat? Here are some pictures of my existing seat post.
It appears that my bike seat has a little part that slips over the seat post .... I'm assuming that all I need to do is loosen the hex nuts on either side and the bike seat will let go of the old seat post and in the new one goes, right?
ETA: will this seat post work? Thinking of pulling the trigger on this one.
