Never, Never Get Punctures = True

I can't tell the difference in rolling resistance between a rubino pro, a gatorskin, and a 23/25c armadillo. I find that the crank length (165 vs 170) has a more noticeable difference.

Does this make me hard as fuck or just stupid?

a little of booth.

I notice a difference, it bugs me, not enough to go and buy new tires mind.
