I guess I should have been paying attention a week ago when riding with Eric - I didn't see his over-the-bars mount. I think it's cool, too. I have been a right-leg-over-the-bars guy for years, sort of tossing the bike under the thigh as the leg swings up. But I've had to compromise since my right hip resurfacing (good Birmingham steel, baby - none of that modern Ti, ceramic or plastic for me!).
Until this weekend I've had to sort of lean the bike toward my left side, gingerly slide my left leg over the top bar and then pull the bike up. With intensive physical therapy I have now graduated to swinging my right leg (oh so carefully) up over the back of the saddle while I lean forward at a precarious angle. I'm tempted to try a cyclocross mount, but the problem is that once you begin that move you're fully committed, and I don't want to take the chance of not making it, especially on a group ride. I figure with another month or so of therapy (stretching, strength work) I'll be back to my old, dashing style. But like Eric, mostly what it has gotten me is funny looks. Sort of like when people used to smoke cigarettes, and a couple guys I knew did that between-their-thumb-and-index-finger think in order to look all Euro.
