I'm very late to the game, but just recently picked up a 2021 Sirrus X 5.0. At 6'1" with a 34" inseam I was between sizes. The XL with its 849mm standover comes within 1 cm of my crotch, while the L with its 483mm seat tube length requires a good 10" of exposed seatpost. While I prefer the reach and stack of the XL, those can always be adjusted with stem and handlebar choice while that standover will always be tight. So I went with a Large, but I'm wondering how other folks dealt with fit on the Sirrus X models.
