I would like to chime in and say that you should feel a difference between the two wheels. The set of our wheels you have is two years old, has been ridden a lot, has a previous version of both rims and hubs. The set you are testing out is a great set and the rim and hub are both going to be stiffer and better handling than the 2 year old Vitesse. Our current Vitesse with our new hubs would be a very comparable wheelset to the demo set and would be more fair to compare. Of course, we are not really in a position to send out a set across country for this type of comparison, sorry.
