just had this my self, and after initially thinking id bought a too short seatpost – im now sorted!
i think i now pretty mich have the perfect feel on the saddle, i went from feeling to cramped, then too laid back, then back to somewhere in between those, and now ive found the perfect setup…
what worked for me was – heel on pedal at lowest point of cranks, leg should then be completely straight, then instead of your heel being on the pedal switch it to clipped in or where you ride with flats at the front of foot, your leg should now have a kink in it…..
thats seat height sorted for me anyways…
after that its fore/aft and saddle dip etc…
i found that if i had the seat too far back and dipped at the front it made me squashed and cramped, and too far forward and slightly up at the front it made me bawls ache and i felt to upright…
so for me whats worked, and i felt completely at home the last 2 rides was, seat in the dead centre of the markers (if of course your rails have the markings), so exactly the same amount of markings either side, and saddle more or less parallel to the ground, i even got a spirit level out to check the middle of the saddle was parallel…this has worked an absolute treat for me but its taken about 5 rides to get it right!
also coincedental that my knee over pedal position is exactly right, which some people measure off to start with, just so happens all the little changes ive made have given my knee directly over my spindle at 3 & 9 oclock….
it will take a few times to get it right, i seriously thought id wasted my money on a dropper that was too short but it wasnt it was the fine adjustment of position on the seat post!
climbing now feels pretty much spot on, feel like im not wasting energy, im not cramped, i feel like my legs are using the most power available and my bawls arent aching!
