What's a good 650X 19/20cc High PSI Clincher?

Anyone know of a good 650cc X 19/20mm clincher that has a high max PSI, like 140PSI plus? I need a set of good race tires.

Continental Supersonics are awesome. I highly recommend them.

While the Supersonic is a great tire, a tire that has a seamless fit on the rim is the faster tire. That doesn’t necessarly mean it needs to be a 20mm tire. For some rims a 23 can be better if the space between the rim and tire is smoother.

huh? seamless fit…? space between the tire and tire? I don’t, but would like to, understand what you are saying.

Seemless where the tire meets the rim. Guess I wasn’t that clear, sorry.
