- I think the OP mentioned it firstA modern invention yet unknown to the masses called electrical tape.
You heard it here first folks
You may have missed the jovial tone of my post- I think the OP mentioned it first
"I used to use some electrical tape on my old bike but that doesn't allow me to push the saddle down only remove completely which I don't really want to have to do".
Off topic for this thread, but my Mezzo folder had this. Problem is, the seat tube is open at the bottom and quite close to the ground, so one wet days grit would stick to the inside. Folding it after riding in the wet got the grit on the seat post, and unfolding it dragged seat post through said grit. In a few months, the seat post was polished smooth, markings gone for ever.Don't a lot of seatposts have measurements on them?
I put a little scratch line in mine with a compass. Small enough that it's not really seen.
Are you restricted by the headroom inside or the door top sill? Maybe angle the bike to get it in and then put it upright? This works for me. BTW what fork clamp did you get? Otherwise, how about just using a ruler?
