well Heine has been saying that for years, but he has changed the world.
Like my other post says, my 60mm schwalbe tires are faster than ANY of their road racing tires (assuming you are riding conditions where weight and aero are not an issue). For me, it was a strange experience first time I put them on...
And none of that makes any difference if you don't run tubeless. Tubes + low pressue = pinch flats.
