This wheelset surprised me from day one with how much flex is in the wheel itself. I'm 220 geared to ride and my riding style is aggressive XC. I like to keep wheels on the ground. After 2 months, I spun out the freehub body and had to walk the bike back to the TH. CC is awesome as they warrantied this out but again 3 months later, same problem. After the second set being as flexy as the first and both freehub issues, I decided to upgrade to the Stans Arch Ex - so very happy I did.
