Question: About how many miles will I expect to get out of these tires?  Thanks.
Document: This is my third set in many years, and the lowest price I've ever seen - way below what I'd expect to pay for two top of the line road tires.
I'm about to purchase my third or forth pair of Conti attack force tires. I ride about 2500 miles and year and do an occasional time trial. I also typically get about 1 flat a year, usually in the spring (I assume due to "trash" collected over the winter). I had my hip replaced in Dec 2009, and didn't race in 2010 or 2011, so kept the same set of Conti attack force tires on for at least 4,000 maybe 4500 miles, without a flat.
After 2K miles, I haven't got a flat yet.Rear Tire (Force) They still have a lot of life according to the wear markers but I'm now at over 2K miles starting get get some peeling from all the glass I've hit over time.I'm using Michelin Ultra Light Road tubes on these and they seem to be a great match. I'm still amazed at how well these have held up in the heat and bad roads.
I've ridden this tire for years, including up and down a lot of mountain passes in Italy and France. In comparison with other performance road-bike equipment, its definitely worth the price. Like a lot of other performance products, this tire doesn't last forever. At some point, the treads will be worn enough that you'll have to replace it. You want 'forever' ? Get a Schwinn with 'fat tires' . You want performance, get the Continental Grand Prix.
They were however smoother riding due to the thin sidewalls, which also means the sidewalls are more prone to damage then most other tires, but most of the Continental line of tires the sidewalls are fragile.I have a problem spending $120 retail for tires that will only last 1600 miles or so at a cost of $13 per mile...that's FAR more then you would spend driving a car including gas and wear and tear!!!
My Michelin Krylion Carbons, while not offering quite as smooth a ride, are much more bomb-proof, so I might stay with them rather than beginning yet another search for a favorite tire. (I LOVE Conti Pro3's, but they don't last more than about 1k miles, and at ~$70 a pop, I won't be making those my mainstay. )I do mostly pretty fast club riding with these tires, on suburban roads.
I just got my first flat on these great tires, with about 1700 miles on them. Made it through the spring without a flat! I did notice some cracks in the rear tire while I was changing it, probably nor unexpected with 1700 miles on them. I also purchased them before my surgery in 2009, so they are pretty old and probably more prone to cracks. I wonder if the previous reviewer might have gotten an old set of tires.
With these GP's that can't be done.They also turned out to be rather flat prone, in those 1600 miles I had roughly 14 flats, and the tires got cut up easily so I had to apply about 8 tire boots to seal up cuts that went completely through the tire, and fill up with Superglue about 20 cuts that if left untouched would have lead to even more flats.I also didn't not think they rolled any better then other tires.
Slapped these puppies on to see if there was a ride improvement over the Gatorskins I've been running. These tires were fast and smooth. Speed went up while effort went down. After the first 20 mile ride, I inspected the tread. The rear had signs of wear off the crown and small cuts and abrasions to the tread! At this rate, these tires will last about 1000 miles max. I really like the tires, but may use them only for race day.
These tires came stock on my Litespeed titanium road bike with Ultegra/DuraAce components. I was concerned that they would be too race-oriented, quick wearing and susceptible to flats given my diverse riding profile. After 3,000 miles of combined training, recreational rides, centuries and road commuting (18 miles to/from work) over 2 years, I am really impressed. In that time, I recorded only one flat, despite the fact that my commute took me over two sets of railroad tracks each way.
Answer: yes
