This is what I thought too but his bike looked quite a bit bigger than my last one and even when next to each other when I had the TR his was a taller bike, height of seattube etc and then when I rode it I realised that the XL would’ve had me reaching far too much. I think I must have quite short arms!
I may be proven wrong when I get it but I’ve confirmed the geo of the 2015 I rode to the 17 one and there’s virtually nothing in it. It literally is different for everyone but their website does say Large does fit upto 6’2.
I had two other cyclists with me too and they both agreed that the XL would be too big, the L feels the right size but also chuckable too!
