I have a Kilo TT and an SST and I prefer riding my SST. I don't understand why people want a track geometry for street riding, it's a lot less comfortable and most track frames have overlap in the <54cm sizes.

I rode fine with overlap for the first month I had my Kilo TT, but after having almost ate it badly because of the overlap, I never want to have to deal with it again. I love my SST.
