That thing is sweet. I really covet the SL7, but I have what is functionally the same thing in hand-made steel, also from 2014. But if you can justify both of those, I should be able to justify getting the 2020 SL7 (or 2021?). The ability to fit wide tires and the threaded BB are the clincher, but I really like the Trek logo on the downtube . They did that very tastefully. How wide a tire can you cram in there if you ignore all the official directives?
