I have two sets of CST tires. 26x1.4" slicks and 26x2.4" knobbies. The slicks are great, I couldn't ask for a better commuting/urban tire. The 2.4"s are ok, I bought them because they were cheap. Not terribly light or the greatest traction but I would buy them again given the choice.

I have never used their road tires, but was considering purchasing some soon. If you buy a set, please let us know how they work out for you.
