Hello everyone, I am looking for some help in identifying these Zipp rims I bought as part of a sweet deal on a 2nd hand bike. The seller didn't have much information regarding them, having bough them second hand. I didn't ask too many questions because I was predominantly interested in the frame. Anyway, the seller mentioned they were 404s, built on Tune hubs. Other than that which is pictured (including a Vclc logo - a technology used by Zipp for 10% less vibration), i don't have much more info. Any help will be greatly appreciated !
