Are you planning on using drops or a flat bar?
Im 6 ft and went for the XL, running a 110mm stem and flat bars.
The L would be definitely have been too small for me, and there’s still plenty of standover height.
Thats with flat bars, I’m pretty sure I could run a shorter stem and drops and it wouldnt be too stretched out. I’ve got short bar ends on and with my hands on them, the reach / stretch is maybe a few cm’s less than when using the hoods on my cross bike.
