    Newbie rider, seat post adjustment range.

    Alright, so I *finally* picked up my Trek Mamba 29'er from the LBS on Saturday. Unfortunately, it has been non-stop rain since then so it is sitting idle waiting for the weather to clear and the work-week to end.

    I did some preliminary adjustments to the saddle height. The Mamba comes with a 400mm seat-post. When adjusted for proper leg extension (heel just touching pedal at the 6 o'clock position) the seat post is only about 1-1.5" from bottoming out in the bracket (I'm fairly short.. 5'9")

    Should I consider getting a 350mm seat post to allow a wider range of adjustment (ie: dropping the saddle when on a long descent) ?

    I *think* 350mm would still be plenty long enough to allow for my proper ride height and allow more room to drop the saddle/shift back behind it.

    I'm still adapting to not being able to touch the ground when sitting on the this is probably a bit of a premature question, but I figured it was worth asking.

    It'll be nice to actually be able to ride the thing.. The wait is killing me!

    You could just shorten the 400mm.

    Very good chance you can ride comfortably with a lower seat heat. You will want it at a height allowing you to be confident on the downhills you ride. You can have it higher if you just ride two track. 350mm used from LBS to test.

    Cut the current post or get a "dropper" post with a remote.
