Maximum seat post extension???
New to folding bikes. The Downtime NOVA seatpost is listed as 550mm long. How much of that can be used/extended? What I am really asking is what is the minimum amount that should remain unextended.
I don't see any minimum/maximum marked on the post itself, as I have seen on other bikes.
So I'd like to mark it myself to avoid any issues as multiple people may be riding/adjusting this bike to their size.
thanks

In general, the seat post must be in the seat post tube for a length equal to at least 2.5 x the diameter of the seat post. If the seat post diameter is 33.9mm, then at least 85mm should be in the tube.

Maybe there are some after market markers that can mark aluminium?
Mezzo and birdie got this right by anodising increments. They stay on for years.
