Continental Grand Prix 4000 Black Chili Compound Road Race Tyre

Product Information

So in my view these tyres are well worth the money, not only for life span, performance, grip, reduced rolling resistance, and puncture resistance.

I've retested the same 25C GP4000S II I've tested in July 2014 for the 25C GP4000S II review. Results were within 0.5 watts, so I've used the data from 2014 to keep the 25C data consistent They're "variable" when fitting them too, some are so tight you wouldn't want to risk using them on a ride because the idea of sitting at the roadside in 5 degrees and rain attempting to get the thing off the rim is just too awful to contemplate. I'll be comparing a 23C, 25C, and 28C Grand Prix 4000S II to see how weight, size, and rolling resistance compares across different sized road bike The all new Vectran breaker belt, developed and patented by Continental, surpasses even the famous puncture resistance of the former leader in this category, the GP3000. The extremely strong Vectran fabrics are more flexible and lighter than all other puncture protection materials. Vectran offers more resistance to cuts than Aramid, is five times as strong as steel and features less weight than a nylon double breaker. It also maintains strength in the wet.

While the tread puncture resistance score is slightly below average, the sidewall puncture resistance score of 5 points is slightly better than most other comparable tires. The Schwalbe One V-Guard ( review) is a tire which comes very close to the Grand Prix 4000S II in the rolling resistance test. The Schwalbe One has a better tread puncture score (12), but a lower sidewall score (4).

With the AS TR, Continental has paired the speed of the Grand Prix 5000 and the longevity and protection of the Grand Prix 4 Season. The new tyre has a boosted tread pattern, multi-layer overlapping ply construction and additional sidewall protection - although from afar it looks very much like a "regular" GP5000. Weight is within +/- 10 grams of manufacturer specifications for all tires. With the 23C being spot on, 25C being 10 grams lighter and the 28CThe tubeless GP 5000 is available in 25, 28 and 32mm widths, plus a 28mm wide 650B version. Our samples of the 25mm versions weighed an average of 302g each; we've seen reliable reports of 295g samples too. That's heavier than some comparable tubeless-ready tyres (a 25mm Schwalbe Pro One weighs about 255g) because Continental has gone for a fully tubeless construction with an airtight rubber layer on the inside. However, a friend of mine has had no end of issues with punctures and poor quality so maybe it's a hit & miss thing? Which it shouldn't be, obviously.

Sure, there are tyres that can boast a more supple rubber and lower rolling resistance that could save you 1.5watts - but these offer an almost-perfect ride quality coupled with a significantly reduced likelihood if spending time beside the road fixing punctures. to know when you decide to go for a bigger tire because you like a more comfortable ride or ride on bad roads with potholes a lot. When testing the rolling resistance of bicycle tires, I always try to use tires of the same size as much as possible to make it easier to compare different brandsIn this updated version of our guide to Continental tyres we've added the new Continental Grand Prix 5000 S TR.
