How much are Zipp 404's in the shops here?
Prebuilt wheels are all fine and dandy if you couldn't be stuffed, well, getting a pair of wheels built, but otherwise they're expensive for what they are, aren't necessarily light or aero, so you're paying for convenience basically.
Plus, I hate being like eveyone else.

You can build these into a wheelset for the same price as Ksyriums but THREE HUNDRED GRAMS LIGHTER.
