Anyone using Zipp 404 front and back as an all purpose wheel? I know they are mainly used for tri, tt, but am considering a pair for all around riding (flats, hills, etc..) Would they be a disadvantage on sprints, accelerations and moderate climbs....or should I say a noticeable difference. I have a Rolf elan wheelset, so I thought why not get a deep dish and use my Rolfs for days when I do a lot of climbing and use the 404s for everything else. thanks in advance
