I know Niner recommends a 400mm, but the post I want is 350mm only. my frame is not here yet (should be a week) and would like to have my post before it arrives. this is going on a MED frame and I have a 33" measured inseam. I am also only 143lbs, so maybe I don't need as much post inserted as others??

You dont have to concearn yourself with how much post there is, thats a generic number they gave.

only thing you need to do is make shure that whatever size you get, that around 4-5 inches are always under the clamp (sorry im shure someone else can give an exact mm amount then that balpark i gave ) So if you keep the seat lower then others you can use a shorter post

Me on the other hand, i need a long post >< and i use a 21 inch frame ><

Given the measurements you just gave, you will absolutly need to have a 400mm post. We have a pretty radilcally sloping top tube and have designed it around the longer post (to have better stand over height). A 350 simply will not be long enough for your inseam and running the post above the max height line will void the warranty on both the post and the frame. I know the longer post does limit your choices, but there are some really great posts in 400+mm lengths. Thomson, WTB, Race Face, Easton, just to name a few.

If you can get a Thompson Elite or Masterpiece then you need no other seatpost, hands down best.

Unless you want a carbon one, and in that case stop taking crazy pills and go get a Thompson... carbon seat post like askin to be nutered in an case of critical failure

ok, thanks for the info. I will order up a 400mm. this bike is going to be crazy light, so I was hoping to of course save some weight here. makes no sense though if it voids the warranty!

Syntace P6 at 31.6 is available in 420mm length. Nice carbon post!

Niner,

what is your opinion of a shimmed 27.2 post with your frames? warranty void?

As long as the shim is long enough to be inserted at least to the bottom of the top tube/seat tube junction, then it's no problem to run a shim and 27.2mm post.
