waterrockets, for a guy who starts out by saying he has 100 miles of tandem experience, you sure are pouring on the baseless opinions. Your single experience has no real applicability as you say you can't tell the difference in stifness between a set of Mavic K's and a set of training wheels. Next to a rear disk, the K is the STIFFEST wheel I ever rode and I've raced them all - in the Dolomites, Alps, Pyrennes, Ardennes, the cobbles of France, Belguim, Holland, Austria, Germany, etc.... You don't lead the league here in single experience.

We have a guy here asking about a faster set of wheels. And some of us, with actual experience, were trying to share with that person so they might be better able to make some decisions.
