I have one with Carbon Record and have been using mavic cosmos wheels until I save up more cash for a nice set. The bike is very stiff, fast and comfortable. A buddy from my LBS rode it a couple of times and said it was faster and stiffer than his Giant TCR. My only complaints are the seat adjustment, 2 bolt set up is horrible, and the noise transmission due to the oversized Aluminum tubes. For 1200 bucks the frame was a bargin IMO. Add the 1570 Record groupo and the bike is sick. The bike is great on climbs, centuries, and can be used for TT's due to the adjustable seat position.
