Our Research Data

At UsedZipp we looked at over 2000+ auctions for used Zipp Wheels on eBay from July 2010-Dec 2011.  The top 10% and the bottom 10% were thrown out.  In addition, if the same wheels were later relisted the original sale price was removed in favor of the later.  Lastly we only used data for stock Zipp wheels - ie Zipp rims with the appropriate matching hub.
