I don't know why someone would do this, well actually I probably would. Anyway, does anyone know if road brake levers will fit on MTB bars? I think most MTB bars have a smaller diameter as you move from the center bulge of the bar to the ends of the bar. If I am not mistaken, the brake lever area on MTB bars is about 22.2mm, but I'm not sure on that. Anybody know if road brake levers will fit onto MTB bars?
