I purchased a Kestrel rt 800 from Bikes Direct and it is great! It came with Shimano DA 7900 all around and with carbon bars and seat post. I have put about 1000 miles on it with no complaints.
I buy it again!
This is off topic, but how much does yours weigh? I weighed my 55cm frame and with 2 bottle cages and a computer, it is 18 pounds. I was wondering if mine was just a freak model.
