without getting into the brand religion type of things, it is very strange that Treks are now cheaper than Specialized. It has traditionally been the opposite, with Trek always being a bit more money in North America than a similarly specced Specialized. At least in my experience of going through bike shopping in between 2013-2018.
With that said, Trek FX is an amazing bike. If I could put my hands on the carbon version in that gorgeous blue, I totally would. But this year there were absolutely no Trek bikes to be had around where I live. The dealer sat empty for over a year now.
The only other issue for me now is the tire clearance. With the X series Specialized has really made Sirrus even more of a lucrative option. Giant Escape, of course, is another bomb, that takes up to 45c. I almost went for Liv Alight 1 DD (same as giant Escape).
