1) 46x17
2) I live in a flat area and I never venture out onto the foothills with my fixie
3) On the flats, I go as fast as my legs can possibly spin.

Question (I'm not used to road brakes, been using standard (vbrakes?) all my life)

How close is are the brake pads supposed to be to the rim? Right now if I flip the brake release lever up and yank the wheel out, it'll touch the tire but still give it just enough room to easily slip out. The problem is, my lever pull length feels really long. Maybe I should just experiment with it later tomorrow.
