I don't have any credibility (yet) so I hope this isn't supurfluos info. I have been running Dice EFD's and SMO's on my last two bikes because I'm heavy, unskilled and value momentum over ability. These rims have been awsome, they haven't cracked, flattened or buckled in two years, and I treat them like shit!
I have Mavic something or others on my Chase, and the rear is starting to look a little "rough".
Good luck.
