I took a hint from Frank Smoak and mounted my 4050s on the curve of the smaller part of
the crash bar. They are "swooped back", and real comfortable for me...
They're not meant to be mounted "on the curve", I bet if I took them off the
crash bar would be distressed where they were mounted, but... I don't plan to take them off...
My heels rest on the forward peg, not the arch of my foot...
