It took two months to get this shipped---but now it is in my hot little hands. The last Felt F55 in 63cm to be shipped this year. Aluminum/Carbon frame with Dura Ace components. Mavic Aksium wheels. Have only ridden it once for 20 miles---but what a difference compared to my 80's steel frame with downtube friction shifters!! A lot lighter and noticably more responsive. And having a 10 speed on the rear vice a 6 speed made an obvious difference. I'm very pleased so far. Looking forward to a 40 mile group ride in the morning.
