I have a Cannondale Bad Boy which I believe comes with a 31.8 diameter flatbar. I would like to change it to something more like a BMX handlebar, because it will provide a lot more rise. Before knowing that there were substantial differences in diameters, I got a BMX bar which I thing may be a 22mm bar. I don't think a shim would be prudent here, but I was wondering if anyone had any ideas on how I could do this. Are there BMX clamps that will work on a mountain bike setup like the bad boy? Alternatively, are there any, more professional "tubes" for lack of a better word that could serve as a shim here?
On the other hand, are there any BMX style bars that could fit a 31.8 mm bar?
I suspect I will get some flack on the stupidity of my predicament, but any positive input would be greatly appreciated.
