Thanks for the answer guys !
Yeah it's a fast tire for me as I never tried something smaller/racier. And I compare them to bigger knobbies in 42 ...
I'm a bit hesitating as a pair of kojak is less than a g-one ... And tubeless is appealing but I never punctured on my kojak.
G-one Allround are quicker. And they have draggy lil knoblettes.
I’d expect the Speeds to be quicker again?
The Kojak is a decent, tough slick tyre. Not very fast Tho.
