What am I missing?

for a few grand you probably COULD go custom!

I like the way you think!

Altitude challenged in size or climbing skills? Yes, to both. I'm 5'4", with legs proportionately small and a torso proportionately long for my size, which renders my body a bit less aerodynamic than those long, lean, sinewy types who climb hills like mountain goats—and also makes me wonder whether women's-specific makes would work for me. Only way to find out is to ride 'em. Woo-hoo, long weekend!
