I have a quick release seatpost clamp on my muni and will sometimes
adjust the seat height based on terrain and riding. If I'm going to be
climbing a logging or other access road to get to a trail I'll sometimes
raise the seat a bit to make pedaling more efficient while climbing. If
I'm on a downhill singletrack trails with rocks and roots and bumps and
drops and stuff I'll lower the seat a bit. For other trails it tends to
be somewhere in between. The difference between the high seat for
climbing and the low seat for downhill muni is no more than 1.5 cm for
me. Not a huge amount of change, but it is very noticeable.
A lot of the time I just leave the seat at the middle position and don't
bother with changing the seat height for the climbing or the trail. I
just ride.
I've got a line scribed on my seatpost so I know where my preferred seat
height is. From there I can adjust up or down a little bit to tweak the
height.
Experiment with seat height to find what works for you. You want the
seat high enough that you can pedal efficiently but low enough that you
can levitate off the saddle to absorb bumps. If you like jumping you
may want the seat a bit lower to get a little extra jump height.
Be kind to your knees. Sitting on the seat and climbing with the seat
really low is hard on the knees. If you're concerned about knee
problems you'll want to keep the seat higher for extended climbs and
extended periods of hard pedaling.
