Now I was willing to accept this if you wanted something special. Mud tyres or spikes or combination road / gravel tyres or even doing 45° angle corner leans at 80kph down Alpe d’Huez or whatever but surely, SURELY, for just going A to B in an paved enviroment it wouldn’t matter?
Yeah no turns out the premium shit does feel great and rolls better. I can never return.


LoL, yes 27" tyres come in 2 or 3 different sizes: with ISO bead seat diameters 584mm, 609mm, 630mm.
650b 4 lyfe
27" and 27.5" are not the same thing. 27" always means 630mm with the exception of some obscure Danish bikes that I’m not aware of.
