    26" bike TT length vs. 29" bike TT length

    If you ride a 24.5" top tube on a 26" bike(frame), will that transfer over to a 29" bike (frame)??
    If you are going to convert to a 29" bike do you need to stretch out your normal TT length or does it matter??

    I'd say your position on a 26" bike shouldn't differ from a 29" bike. If you have geometry that fits you, I'd go the same route on a 29'er.
    MTBR is serious stuff.

    Unless you were using a stem length that was imperfect, I wouldn't adjust toptube too much. A tad longer does work nicely often, along with a shorter stem, but you don't have to.

    TT length should be the same as what you're comfortable with on a 26-inch bike. If you're going with an off the shelf frame, look for a TT that falls within an acceptable range that when combined with proper stem length, puts the bars in the same position as your current ride (assuming it fits properly). You'll also want to consider stem angles to get a proper position. Most 29er frames end up with a higher front end due to the taller wheel. This may mean you'll need a lower rise stem than your using on a 26-inch frame.

    It seems to me that with 29er geometry most 29ers have longer TT and use shorter stems.

    I learned this lesson for $1200.

    Consider toe overlap, as the front wheel will be 1.5" closer to your pedal even before you put Exi's or another big fat tire on it.
