This is a true statement. If you normally ride a 56cm "classic" fit or "square" fit being 56cm ST and 56cm eTT, both center to center, then with a Surley Cross Check or LHT you should consider sizing down to a 54cm and likewise for the other frame sizes. The 54cm Cross Check has a long top tube and a high bottom bracket since it is technically a cycle cross bicycle. Go by the eTT length for frame sizing as long as you can get full and proper leg extension.
