My road bike (titanium frame, Specialized tri-spoke carbon fiber wheels, Dura Ace components) used to be pretty fast, but I think something's gone wrong with it. Over the past few years, I've noticed it just keeps going slower and slower. Hills I used to be able to go up in a 42x15 now require a 42x21.

I'll bet there's been tectonic shifting and the hills are steeper now. Yeah. That's gotta be it...
