I currently have a 400mm seat post, does this mean I would be best of getting the 420mm reverb? I’d like the 5″ travel version if this effects anything.

I tend to run 5-6″ of post of of the frame, whats the deal if something happens to the hydraulic remote hose? For example, if I was to crash and put a hole in it, can I stick the post up enough in the frame to get peddling height from it, or does the seat automatically return to full height?

125 drop needs 190mm from top of frame to saddle rails so you will need more than 5″ sticking out- check where you are measuring to and see.

Overall length determined by how much left to go in the frame.

Awesome, thanks gravity-slave. I’ll set it to my ideal peddling height and see how much I have between the frame and rails.

How does the post react to a broken remote or hose? Do they stay in the current position? Go down? Go up?
