I just bought the complete in black. I'm 6'1", 270 so I'm one of the bigger guys here as well. I put the Tiagra STI shifters on it. I think I will get a different saddle because it's too narrow for me. I'm going to ride the rims for awhile but I am going to look at some bigger tires, maybe 700x35 instead of the 32's that came on it. Other than that, I will probably leave it as is and see how the upcoming season works out. I did one race last year and loved it so I'm going to try more this season.
