Running 28s on a Specialized Roubaix (2014 carbon frame) they rubbed. When calipered at 100psi they read 32mm. Changed to the 25s and had perfect clearance. The 25s measured 27mm at 100psi.
1400 miles in 6 months (40-100 F) on smooth to chipped surfaces with occasional pot holes
No issues and minimal visual wear
I have been riding Continental tires for about twenty years. They have only improved their products and I appreciate the durability.
My latest tires are 700 x 25 and it has made a noticed improvement without any disadvantages. The ride is even better.
I bought these to replace a set of Schwalbe Marathon Plus tires specifically because I was looking to reduce weight and rolling resistance. Based on research, this tire seemed to check both of those boxes while still providing reasonable puncture resistance.
These tires run incredibly smooth and effortless. As for puncture resistance, I just returned from a weeklong bike trip covering 500 miles of rural roads littered with sharp rocks and steel belted tire shards and didn't have one puncture. I even did a little gravel riding (less than 10 miles). I cannot comment on traction in the rain as I plan to use my Schwalbes for winter commuting, however due to the low weight and very low rolling resistance, I very highly recommend these tires for any type of distance riding (multiple day trips, or centuries), they exceeded my expectations.
Conti GP 4000 S II, great all around tires. I've been using these for racing and riding for the past two years. I would say I get about 2000-3000 miles out of a tire, so they do last a good while. They handle great and are nice and fast.
They also provide very good puncture protection for a high performance tire. I know there are other 'racing' tires on the market, but they are very light and thin and certainly put you at risk for flats. From my past experience, there are few things that take you out of a race as fast as a flat tire.
If you balance price, performance and protection I don't think there is currently a better tire on the market.
Not much more can be said about this tire than has already been said. There is a good reason you see it on so many bikes. The GP 4000 is a solid all arounder tire for enthusiasts. Plenty of grip and relatively high durability. Plus it looks good on the bike.
One thing to note is that my 28mm pair measures to about 32mm on rims with 19mm inner width so be careful on bikes with limited clearance.
I used to ride exclusively on another brand of tire. A riding buddy said I should consider Continentals. The pair I ordered from Western are my reserve tires. The first set I bought ARE STILL GOING STRONG....5000kilometers ( about 3000 miles) ....NO FLATS !!!
I run the Continental Grand Prix S II road tire on three of my four road bikes. They simple are the best tire for the money. Good rolling characteristics, puncture resistant and long lasting. I have tried other brands with no where the success of these fine tires. Highly recommended for your road cycling both racing and training.
This tire has just the right amount of road-gripping firmness while delivering a very comfortable ride. I'm very happy with the feel and handling. Its a big improvement over what was on my road bike previously.
Continental is still the gold standard in cycling tires. I use them on all 4 of my bikes. Gatorskins on my commuter bike, 4 Seasons on my winter road bike and these on my race bikes. The ride quality is superb. The handling is excellent. These won't last as long as the Gatorskins or 4 Seasons but that would be true of any premium tire. Get them on sale and they become a good value.
