I own an enemy that I have built up for racing this past season. I spec'd some pretty trick parts but even without those this thing rocks. The frame geometry is really likable and very responsive. It is fairly light and the aluminum rides very well. I had not expected such performance from a value priced frameset. You can also run discs on it which is pretty freakin cool. Mine has avid mechanicals with King hubs and XTR/Dura Ace parts. Good luck.
