Possible to shim a 22.2mm handlebar for a 25.4mm stem clamp?
I bought a new handlebar for my recumbent that turns out to have a 22.2mm diameter. Apparently, all of the stems in this size are exclusively for BMX bikes, and none of them are long enough. I'd like to shim the bar to fit in the clamp of the 25.4mm threaded stem I already have, but I'm not sure how feasible this is using something like beer cans or old tubes.
I kind of think it will be ok, since the forces on a handlebar for a recumbent are much lower than those of an upright, but it still is a pretty large difference between the two.
Also, if anyone knew of 100mm+ stems with a 22.2mm clamp diameter, that would work too.
