I know this has been discussed on the Forum about a million times, but I would appreciate if it were discussed once again.

What benefit, in terms of time, can a person that rides arond 22/24mph (around an hour for 40K) expect by switching from an aero wheel (Zipp 404 in this case) to a disk (Zipp disk with 404 front in this case).

I guess the disk will be ridden on flat courses for the most part, so lets assume a flat course for this example. Wind and other variables we can assume to be "normal".

Thanks
