    Outcast 29er Head Tube Length

    Hey, I'm looking at buying a motobecane outcast frame for a 29er buildup. I'm going to buy the 21" frame. I'm looking for used forks but cannot find any specs on the head tube length. Does anybody know or could one of you fellas find it in your heart to measure your 2009 frames? What is the minimum steerer tube length that I would nee? I found a great deal on a fork that has a 190 mm steerer, will this work?
    Thanks in advance, I really appreciate it!

    I have a 21" Fanton 29 frame (2008? I think), and I think the HT length is around 140mm. I KNOW that it's less than 155mm because I moved the parts to a new frame with a 155mm HT.

    I know that's not quite what you asked, but maybe it will help.

    Thanks, that helps. If it is 140 mm, then that leaves me 50 mm to attach the stem, which should be adequate.

    Does anyone else have a 2009 frame that they can measure, or know exactly what it is?
    thanks

    Don't forget the stack height of the headset

    I just got a reply from Motobecane. Apparently it is 125mm for a 21" outcast frame. See their response below.

    Thanks for choosing Motobecane USA
    15" .....8.5cm
    17"......9.5cm
    19"......10.5cm
    21".......12.5cm

    Best wishes,
    Jay M
