Should I 125mm or 150mm on a dropper post? I've ordered a 125mm Fox Transfer for the Production Shan. Basically, I have a 250mm stack height (this measured for my climb / flat out on the road pedal stroke) and the entire seat post is 380mm and fits completely unobstructed into the frame (ie, the saddle can slide down butt up against the seat clamp). As I'm externally routing (thanks Production Privee
), the only choice comes down to how much drop I want.
I thinking that 125mm at max extend will leave 125mm of the actual post above the seat collar (if I'm reading this right), so fully dropped, the saddle will still be 125mm above the collar.
Therefore, I'm not sure I want or need 150mm.....
Thoughts?
EDIT: Thinking about it, as I'm externally routing, 125mm is the better option as that will leave, effectively, 125mm of exposed post offering a nicer curve for the cable than the 150mm drop (which would leave only 100mm).
