My Cinqo is in the mail and I got a set of 404 aluminum clinchers and they weigh the same as my custom DT Swiss RR1.2 (30mm depth) with PowerTap wheelset. There'll be roads I don't know and won't want to experiment with the 404's so I'll ride the alums (after I sell the PT and get a 240S hub built one). Once I know where all the potholes are I'll switch. So, I consider my aluminum wheels my seek and destroy set. GL
