You guys jumped right over the basic question and into which model to use. Does this imply you think I should use them?
Is this the XN to which you refer, Vittoria Cross Evo XN?

The Vittoria web site refers to the size as 28". I assume that is 700c to me, our standard tubular tire rim size, correct?
