It's very strange that they didn't use the GT Road wotsit.
And I'm always amazed at how different tyres 'suit' some bikes more than others, even across a wide range of rider demographics. Sorry, should have warned of a big word coming up but tooearly for the brain to be engaged...
And, for the penny-pinching among us, we have no idea of useful life comparisons.
But you are right Matt, the profile difference is obvious even to me and I'm still 😴
