I bought some fairly nice Sun Race 8 speed indexed thumb shifters, intending to put them on a road bike, but the clamp busted while tightening it down, even though I widened it with a dremel. Now I have a set of busted shifters with no way to mount them. Was hoping to find a creative spot near the hoods to mount them, and use them as a set of a poor man's Gevenalle shifters, but no dice.
Had no idea that MTB bars were so much smaller in diameter than road bars.
