    Couple questions Transam

    The majority of my build is coming off an old bike, hence the questions

    I'm 5"11.5 and leaning towards the medium will be run with a 50mm stem and 750mm bars, all ok? I won't be squashed in to the bike?

    Chain set is 2x10, was planing on ditching the front derailleur and running it 39/36-11, need to replace my rear derailleur, does the Medium shimano XT St+ manage 11-36

    What spacers will I need on the front BB

    160mm forks ok with a zero stack HS? A2C 550mm

    Will the 2014 have the routing for a stealth seat post?

    Probably seem like silly questions, but thank you for any help

    I'm 5'9 had a medium frame ran 70mm stem 725mm bars and still felt stretched out. If you like a upright feel with your height and with your setup the fit should be perfect. However, a 160 fork would shorten it up even more I would drop it down to 150. I ran a 150 and more than that and it would have felt unbalanced. I ran a 1 x 10 and used one spacer with deore cranks.

    Medium will be a tighter cockpit and a bit more of a playful fit, a Large will be more towards the AM all day thing is my opinion.

    The medium cage can handle the 11/36, but not your 39T front, get the long.

    You didnt mention what crankset you have?

    TA has a 44mm head tube, you will have an external cup and Im assuming you will have a tapered fork. 150mm will be more desirable.

    No internal routing for a Stealth on the TransAm

    Large frame. Med will be way too small unless you use it as a bmx bike.

    The med cage will work better as the size of a single ring up front does nothing to require a long cage.
    SPD pedals are an absolute menace to the well-being of the world, and ought be banned immediately.

    Thank you for the replies, a 26 Transam of any flavour is prooving difficult to source atm (UK)

    Some napkin maths and some very good help from the guys Transition suggest that the geo from the 650B ran with 26 wheels and A2C of 550mm would give a theoretical BB height of 12.3"

    Regards the 26'r I was edging towards to medium as it struck me as more playable
