    Handlebar stem dimension help needed.

    I'm stripping a damaged 1994 Trek 2200 frame and adapting the components to a 2001 Giant TCR ONCE frame. I'm old school and anything other than quill type bar stems is new to me.

    The Giant steering tube is 1" diameter and the bars I intend to use are 26mm. Being I'm not prone to opting for the most glamerous parts I've found a stem for that combo from Bike Nashbar and even a shim on eBay to fit my 26.2mm seat post to the 31.6 tube.

    Anyway my questions: Is there basically a standard/recommended stem length for a properly fitted 53 c-c top tube (horrizontal center of seat post to center of steering tube is 55cm). On my mid 80's bikes w/ 53 top tubes I used a 90mm stem, but I'm thinking 80mm on this frame, what say you? Next question, I assume the stems have a standardized steering tube clamp height, is that correct, if so how much space does it cover? Last question, where can I find a headset cap for the 1" steering tube?

    Thanks in advance, SKeown

    threaded? is that 1" ID or OD , makes a difference in the stem, 1" OD the stem is 7/8"
    stem is 1" when the fork is 9/8"

    bodies of riders are not standardized.. cant type my way to fitting you from here.

    It's 1" OD threadless tube.

    The stock stem length for most early 90's road bikes with a 53cm is 100mm but you should be able to run a a stem 10mm shorter or longer just fine. Early 90's or newer bikes tend to run slightly longer stems than the old school tuff.
