Just considering options is all. The kilo tt is the go to bike from reading the various posts. I like the relaxed geo of my roubaix how does the kilo tt compare? I weigh 270 at 6'2", other than the wheels any worries with the tt at my size? I'm guessing best option is to get a tt and swap out the bars and stem to make it a bit more relaxed. I'm 40 but enjoy riding but my back doesn't always agree to aggressive setups.
