This article has been partially replaced by our Continental Grand Prix 5000 23, 25, 28, 32 mm comparison. The newer Continental Grand Prix 5000 article is much more detailed and includesThe tyre does make my bike roll with a lot less effort and will continue the roll for some distance without power. All that to say, you aren’t going to lose your local race because you have Grand Prix 4000 S II tires on your wheels.

Lazer Grip: To make you one with the road, The lasered micro profile structure expands over the tire’s shoulder and provides outstanding cornering. even bigger. At a comfortable 80 psi, you're only giving up 2-3 watts for a pair of tires when going for the 28C size. That's goodContinental's not saying exactly what wizardry of rubber formulations and carcass construction has been wrought to achieve this, but it's impressive as hell, especially when you consider that the improvement over the clincher version of the GP 5000 is 17% — Conti only claims 5% — and the tubeless GP 5000 therefore has over 30% less rolling resistance than the GP 4000 S II. That makes it the fastest Continental tyre yet.

Noteworthy is the very flat rolling resistance graph of this tire, dropping air pressure to 80 psi increases rolling resistance by only 1.5 watts per tire. This is a great feature because rider comfort will increase greatly at 80 / 90 psi at a very low cost. As noted previously, the measured weight is 215 grams which is less than the 225 grams specified by Continental. The Grand Prix 4000S II is also quite a big tire with a width of 27 mm and a height of 25 mm on a 17C rim. All in all, not bad for a tire with a weight of 215 grams.Off-course, what will be won in the rolling resistance department, will be lost in the aerodynamics department.
