  1. Before I go out and actually do it (and screw up), I'm vetting my idea
    through you learned people.

    I need a handlebar and I've an idea to get one welded thus. I'm gonna
    get a 2nd hand bike stem, get the 'handlebar clamp' part sawed off and
    weld a Y shaped extension to it.

    Question is - a) would it hold b) any flaws to my idea?

    Opinions much appreciated.

  2. why not just clamp your y shaped tube in the handlebar clamp?

  4. Which bit are you clamping onto the frame?

    If it's the handlebar clamp, then you need to be sure your seatpost is
    25.4mm. If it's the steerer, then either 25.4 or 28.6mm (I dunno, maybe
    you could shim a 27.2mm post like on the KH into the bigger size)

  5. Although if your seat post is 22.2mm you can use a bar end on the seat
    post and weld an extension handlebar to this. I ran this setup for a
    couple of years before cutting it down to hold my bar end lever (as a
    brake lever), like Joe I've stopped using handlebars.

  6. Kington99: Because it'd then make my handlebar crooked. I've thought of
    making a U-shaped bar extending from the stem but I think it'd be too
    wide at its minimum and my legs will be rubbed raw... any suggestions
    mod it any other way?

    Joe: I'm using the clamp that would usually go on a bike's headset (no
    idea what it's called). I've no idea how wide stems are - I guess I'll
    have to ask.

    Keith: How do I do that? I'm going for welding an extension to a stem
    because it's hollow and the overlapped part would be stronger (am I
    right?). Also, the clamp portion looks more likely to hold. If a bar
    end holds just as well, I'm keen too. Do you have a pic?

    Stems are 1" / 25.4mm or 1+1/4"/ 31.8mm depending on what you got it
    off. If it's a cheap bike stem, it'll probably be 1" / 25.4mm

  8. Most modern MTB stems are 1-1/8, very few 1-1/4 (old yetis used to use
    this size but is rare at least in the USA)

    There is some good info here:
