    OK to extend a seatpost?

    I see on here that some people have extended the seat post by clamping another one on top.
    Is it a safe way to to do it? On a folder?

    I have a Dahon 3 speed that came from Dahon built like that and did the the same thing to a Raleigh non folding Twenty I ride. The key to success is to have a vary snug fit before clamping the posts and at least 2 inches of the one post into the other or the frame. Roger

    I have never seen a Dahon 3 speed that has a built in seatpost extender like that - can you post a picture? At any rate that is very different from modifying the seatpost *yourself* to do such a thing.

    You've ascertained that the seatpost is actually not long enough for you? Brought the post up to the maximum? We've sold hundreds of dahon folders in the last 2 years, not one has had a problem where the seatpost isn't long enough. I'd be very cautious attempting something like this unless you're sure you can engineer something that won't fail.

    a seatpost extender? other than perhaps a folding bike with some type of 'telscoping' seatpost I do not think I ever heard of such a thing. if the seatpost needs to be extended chances are real good the frame is just too small
