No real complaints on my 5000, other then the wheels. It had that solid rigid feel, alot of people complain about the wood feeling from the frame, but then other people complain about "to much vibration" on other bikes, i myself liked the frame quite a bit. Either way, get this year's model if you decide on the 5000, cause next year the frame changes, it does go up to 10spd, but the components go down to "select" and 105, not horrible if the frame where the same, but overall unless you get it at a big discount from the msrp, just save your money and go with the madone 5.2, full ultegra 10spd, and better frame then TCT.
