So I've had this problem for a couple seasons and always thought I had it "fixed" and am realizing that I don't....
I have Zipp 404's (650 tubular) from 2003 (newer design, carbon dustcaps, no dimples) and they are on my Cervelo P2 (not P3, not P2k), which has a stock Profile BSC fork. When I clamp the wheel into the dropout (tightly - with Zipp Skewers although I imagine any skewer would be the same) there is a very audible "rub" noise coming from the hub that I believe is being caused by the dustcap being compressed by the fork (when clamped) against the hub.
I can sort of "fix" it by lifting the front of the bike when I clamp the wheel in place essentially dropping the wheel just a teeny bit lower in the dropout (maybe 1mm). but as soon as I hit a good enough bump, it whacks the wheel higher up into the dropout so it starts rubbing again. When held off the ground and hand spun, the "rub" definitely impedes the free spinning of the wheel.
So what to do? is this a known incompatibility? I guess the costly fix is buy a new fork. What else can I do? Can I just rip those carbon (or faux carbon - I don't know) dustcaps off of there? Will that negatively effect wheel maintenance? Anything else I need to know? Tom D? - Because you know all; JoshatZipp? - for obvous reasons; Anyone else? - you all know more than I.
Thanks a ton,
Don
