Road cycling is what I live for. I need to have confidence under my bike to ride my best. These tires give me the confidence I need to smoke the competition even if its just me going for the latest KOM. Sure footed, puncture resistant and well fitted tire that will give you many trouble free miles.
Been using this tube for a number of years..resist punctures quite well and still pliable to make an easy change.
Easy to mount, rolling resistance is average to good (not spectacular? ). I ride about 60 miles a week over Seattle streets through multiple construction zones and thus far only one flat after 500 miles. To be fair, it was a one-inch jag of glass that cut through all layers, but I would think that with all the ballyhoo about Vectran that this would have been less of an issue. Not quite as tough as the Hardshell, but the ride quality is palpably more smooth. They were on a 40% off sale, so the value at that price point is good, but full retail seems a little high for what is promised to be an almost invisible flat-protection system.
These tires provide amazing grip and stability without the sacrafice of speed. I was a little hesistant at first, however, I switched into these from a pair of 4000's and felt nothing but improvement. I commute to work and ride year round in northern NJ. I can't believe I didn't start riding with these sooner.
Purchased for Bay Area winter riding where there could be debris and wet roads. Performing great!
Side wall blowout on a descent. Very dissatisfied. After only 50 miles, side wall separated and intertube bulges out and popped.
I don't give much credence to subjective individual reviews of tires because, well, they're subjective and one person's experience is largely statistically insignificant. I bought these because they measure well for puncture resistance in at least one testing website on the internet (google bicycle rolling resistance) and have acceptable rolling resistance numbers. There are other tires with better puncture resistance but their rolling resistance are higher, so this seems like a good compromise. I have no complaints about how they ride.
Always ride rough back roads , cannot stand city traffic. Have gone through a few sets of these tires with no issues ,real tough tires . Sizing runs a little small 70025 is like 70023 grand prix4000s
I use these tires on my off-season rain bike in Portland. Usually there is a lot of junk on the road during this time, so I need some beefier tires and these certainly are doing a good job so far. I only have about 500 miles on them so far, but no flats yet and no noticeable rips or tears. I got the 28 version and they look at least 28 on my rims when mounted, but I don't have a caliper so can't give an accurate number. I also run these at 8085 PSI and they feel great.
These have become my go-to tire the ugly months of off-season training in Portland. They do everything I could ask. They provide enough puncture protection, they have good grip on wet and messy roads, they have a long wear life, and with all these blue collar attributes, they manage to be reasonably lively and supple. These tires hold all the qualities we need during winter months in perfect balance.
The tires are really good tires when it comes down to the Vectran material.
Great fallwinter tire, no issues with punctures and I even kept my previous pair on over the summer. Not quite as responsive as GP 4000s but sufficient for almost every situation.
These are my 'go to tires'. I'm a recreational road rider, doing about 100 miles a week, and find these guys to be very puncture resistant compared to other brands and other tires from Conti. They also have a pretty good supple road feel, but not quite as much as from some more vulnerable tires. I typically ride them about 2500-3000 miles between changes, and have gone as long as 4000. By then the rubber is just too dry to give a god ride. Good in wet or dry conditions.
Buy on sale and they're a fantastic value.
Only about 50 miles thus far due to limited riding since purchase around Thanksgiving. Looking forward to Spring riding. However the first 50 miles have been great handling and low rolling resistance
I moved to Portland riding Michelin ProRace 4 but they flatted too often here.
At first I tried Gatorskins and although bulletproof, they were no fun to ride.
Next I tried the Gran Prix 4 Season. It rode quite well so I put a set on my rain bike too.
Two years later, I'm still a big fan of this tire. In fact I ride them year round.
I started noticing a lot of local riders had discovered them too which confirmed my belief that I'd discovered a great tire.
As the locals say if it lives here in Arizona it either has fangs or thorns. Landscapers leave quite a bit of debris on the roads and ultrafine thorns can flatten most tires. We don't have 4 seasons but the Vectran layer has kept me rolling with relatively few problems. I felt the difference in ride with my first pair when I switched out the factory rubber on my Roubaix and they grip well cornering even on the rare day when the roads are wet.
Use this tire on my trek road bike. They last for lots of miles and have excellent flat protection.
Ideal winter tires - when these were new, I locked-up the back brake and skidded the back wheel and thought I must have scrubbed the tire badly, but there wasn't even a scuff on the tire surface. This would usually imply a tire with poor grip, but that isn't the case for these Continental tires - they grip well wet or dry.
Tire wears well and provides superior puncture protection. Good value for the dollar.
use these all the time
