Fitting a looooooong dropper post

Modern mountain bikes are literally designed around dropper seat posts, and the name of the game has quickly become how to fit the longest possible drop post into your frame.  With frames having various possible insertion depths, and with steeper seat angles, the measurements you’ll need to buy the correct post might not be as intuitive as one might think.

Ripley LS Seat Seated Height

Basic formula: Maximum seat post inserted length minus frame’s maximum insertion depth.  If it’s a positive number, then add that to the distance of the center of BB to top of seat tube and that will equal the lowest possible seated height.
