I do mostly trail riding, from gravel to asphalt with occasional dirt single track and State Park mountain bike trails. I have over 3000 miles on my current set of Top Contacts and have had no problems. When riding on asphalt roads or trails, I pump the tires up to 65 psi where they ride wonderfully on the closed center strip, and when going off road, I lower the pressure down to 30-35 psi, and the edge tread works great on the gravel and hard mud of softer trails. Have never had a flat, and the tread still looks near new. I have done 2 Michigander tours the last 2 years of 350 miles each over varying terrain and they have performed flawlessly. The little bit of extra weight is absolutely worth the durability built into this tire.
We used this tire (700 x 32) on our road tandem for a 2 week cycling tour through Vietnam and Cambodia. Most of the roads were uneven and pot holed pavement, some coarse gravel and a lot of compacted clay and dirt. While many other tandems and single bikes experience multiple flats on the tour, we had none! The tire provided good traction on the loose gravel, sand and dirt we encountered in many areas, yet rolled well on the smooth pavement where we could ride at speeds approaching our standard road tires. While the tires are a bit heavier than your more standard performance road tires, the extra rubber and material in the tread and sidewalls added durability that is desired when touring on rough roads in foreign countries where support may be limited. When you take into account the extra weight of a second rider plus bags with supplies and tools on the tandem, we were impressed by the durability under the heavier load.
I bike to work 100-150 miles a week on a Specialized Turbo e-bike. I'm running these in 42. They're wonderful. Light, comfortable, and sure footed. Had for a month or two and nothing but good things going on. Great on grass, gravel, dirt, good in the rain. Much faster and less harsh than the OEM Armadillos. And those were pretty nice tires, not knocking them at all.
It's a big cushy tire with good grip, long life, and good puncture resistance. I would say it has a good ride... except... after just a month and a few hundred miles, it's so out of round the wobble is surprising and really annoying except at pretty low speeds. It's also hard to get it to seat evenly on the rim.
I'd have expected better quality. At this price, forget it. I've had other Continental tires before and never had this problem to such a degree with any of them. I tried the tires on several different rims that are all very round, with which I've never had any trouble getting other tires to sit right and run true. Now they're on my commuter bike that never sees high speeds or long rides.
Where I bought 'em, they said they'd have warrantied them except I didn't bring them back quite within 30 days. Instead they sold me a set of Panaracers at a discount. They said they'd seen this problem a lot with the larger Continental touring tires.
These are tough tires with low rolling resistance. If you have a touring or utility bike that you load down and don't want to have flats these are a good choice. They are a bit heavy but that is the tradeoff. I would rather ride my bike than fix flats. Given the toughness of these tires they have very low rolling resistance. Would I buy them again ... Well yes, these are replacemnts for the set I wore out.
