Well, really I've made lots of mistakes; the one I'm talking about, though, is that I recently ordered a Kilo TT frame from BikeIsland.

I am 5'10" and I ordered the 57cm frame. I figured that 57cm would be fine, because the conversion that I have been riding for the last 2 years is a 60cm. It seems like most people tend to like to get a smaller frame as opposed to a perfect fit. Should I be getting the 53 or 55cm instead?

Thanks
