Really fabulous. A big jump up on the 3000's (no s!) in rolling resistance, grip and comfort. I'm tempted to try some of the new Michelin Pro Race 3's, but am reluctant to change the 4000s's. Currently in about 4000 k's on this set, and they seem to have plenty of life left.

There was a big tyre shootout in a local French bike mag, where they did lab tests on grip and RR, and the 4000s's came out near the top, certainly amongst tyres that you could use on a daily basis. And speaking of punctures, I never did this well on the 3000's.

So .. guess I'm a convert.
