I find it feels perfect for me. I’ve got a large and I’m 6ft 1. I did the canyon measurements twice – first time I was a medium then second time I was a large. I’m no expert but I think the wide bars help it feel good. If it had narrower bars maybe it would feels like you was sat tall in the saddle.
My brother is 6ft 3 and he did the south loop at whinlatter on it and even he said it didn’t feel small or cramped. And he’s got arms like a gorilla.
