I have asked some felt questions and the reply that I got was the eat tube was too short and the top tube to long. But it fit my body well and I was impressed with the ride. Every one says avoid aluminum but this bike was very comfy and winked at me when i went by too. Needless to say my Felt 65 with full 105, mavic rims ......... for less than a grand is sitting on lay away right now.
