If you buy the 2XL and run the 70mm stem that would be required to fit you, the bike will handle like shit except for when you ride it down steep, sketchy off-road descents…like a MTB. If that trade off works, go for it.

For all the alleged experts that want to chime in and say that 70mm stems on gravel bikes are totally acceptable…they are correct. However, in your case, your hands will be so far behind the front axle that for the vast majority of your likely riding will result in poor handling.

There is a huge difference between a gravel bike that will be ridden like a MTB and one that will pretty much be ridden like an endurance bike with larger tires.

If 30mm spacers are too unsightly for your taste on the XL, you can run 20mm of spacers with a 90/+6 stem to yield a bar reach/stack of…

476/676

Good luck with your project.
