Swapping handle bars, 31.8 -> 25.4, flat -> drop?
My hybrid/touring bike came with an adjustable 1-1/8" threaded quill stem on it and I wanted to swap the stem out since it was flexing and creaking so much (and I haven't had to adjust it at all). I had a hard time finding a stem in that size, so I was happy to see one on nashbar w/ the same angle I've had my adjustable stem set at:
I ordered that stem a couple days ago (and I should receive it in 2-10 weeks or however long it takes nashbar to ship stuff) and I was reading some more about stems when I realized the clamp diameter on my handlebars is too big for that stem. I don't have any calipers but I roughed it out with a metric tape measure and it looks like it's an oversized flat handlebar with a 31.8 clamp diameter, while the clamp diameter for that stem I ordered is 25.4
I was looking at Sheldon Brown's cribsheet for handlebar diameters here:
If I were to get a new 25.4mm drop bar / touring handlebar (I was hoping I might be able to change eventually anyways), would I be able to use my existing brake levers and shifters on it? Based on that crib sheet it looks like they would both have the same grip size (23.8).
If so, would it be practical to mount them on the top part of the drop bars and ride it like flatbars (w/ the added benefit of the extra hand positions)?
