Tubular or clincher?

[Andrea]

I use tubular wheels/tires for races and clinchers for training. Yes, tubulars can be inflated to a higher PSI (mine go as high as 220), but unless you're on a freshly paved road with no imperfections, that would be bone-jarring (I usually inflate to 140-170, depending on the road conditions)
You can flat with tubulars, and in order to change them, you have to get the tire off of the wheel- something that can be pretty tough & messy to do on the side of the road. Also, if you do a road replacement, you have to be careful riding on the new tire, because if you corner hard, it can roll off until you get home & apply new glue or tape.

Clinchers are heavier and have more rolling resistance, but their convenience is great.
