So I took out the 5.5 for it'a maiden vouyage yesterday and even thou I did test ride one after a true and proper fitting all I can say is well, I don't know, I'm speechless. This bike is amazing, the difference form my old ride is night and day, it rides so smooth yet amazingly responsive, the Sram Force is also grest, it changes gears so fast it will take awhile to get use to it. Did a short 54km ride with 1500feet of climbing so I had a bit of everything in this ride. The Bontrager X Lite wheels roll fantastic such a lovely sound while cruising. I can't wait for my first big ride. I really am amazed and am estatic I bought this bike, I have heard many times a bike will not make much of a difference and I've always backed that up, well I'm not so sure about that now. I did this ride on 3 hours sleep in last 48 hours and yes I was pumped about ride but it was just so effortless. Well I better stop or this post will go on forever. I will end it by saying if you are thinking of getting a Madone stop thinking and just buy it!
