Upgraded from the Enve AG25's earlier this year. The AG25's were a decent wheelset. Nothing to rave about but, not terrible. I cannot believe and never would have foreseen how much of a drastic difference there is in the ride and handling of the G23 over the AG25. I had hoped for some improvement but, stunned by the drastic change. It's like a completely different bike. The G23's inspire confidence on high-speed descents. They roll faster, climb better and add stability to the overall handling.
