THEN AGAIN!
The C2s DO mount pretty close to the stem. Maybe they'd work. I'll try at some point and report.
But, seems that once the pads were set reasonably wide out, they'd be in the way of 60% of the moustaches. Maybe if the m-bars were inverted?!
I really will overthink this stuff.
It would be awfully nice to tour with moustaches and aero, point being.
