This thread is about ugly/not ugly, so....IMO:

Shimano should have stopped at the 9-sp Ultegra crankset. I'm not much on cranksets that look like stacked plates.

Older Ergos are OK, because they look like older brake levers. All STI's and the newer Ergos look like the baby in Aliens.

There is an elegance to C&V bikes with slender metal tubing, quill stems, DT shifters, but there is something clean about the look of aero brake routing.

Despite what I like, I tend to build and ride what is most convenient for myself and anyone who would ride my bikes. I'd ride a Fuji DR 6.0 or a P4C if someone gave me one. That all being said, Trek Y-Foils are both ugly and not ugly.
