I was riding on Schwalbe 1 tires for years and they are excellent... However there was one draw back... I was getting a lot of flats and ruptures in the side walls ( I must say though that the customer service was excellent.) However I just got tired of flats. I was looking for another tire to replace and read the outline on the Conti Attack Tires with the smaller in the front and the larger in the rear. So I thought that I would give them a try. I have a couple of hundred miles on the tires and they are nothing less than EXCELLENT. I have dropped the tire pressure to 105 and I still get the speed and durability (So Far.) I am very pleased with the tires and the ride is much, much smoother and just as fast. I would definitely recommend these tires.
Bullet proof tires, these have stood up well to the rocks and road debris in my area. The only flat I had was from running over a steel wire brush on the road, which any tire would not have survived. Conti is the best brand, these are the best tri tires.
I have been using Mavic tires for the past several years. I wanted to try something new and so I bought the Continental Grand Prix attackforce clinchers. So far, I have been very happy with my choice. The ride is much more comfortable, handling is good and rolling resistance is better than with the Mavics. A solid choice!
I was using 4000S chilis 25 rear, 23 front and just replaced them with the Attack 22 F Force 24R. Visually the AF combo is smaller with a slightly different tread pattern. They seem to ride a tad harsher. probably due to the size difference but they hook up with the road the same.
I mounted these on my Boyd 90mm carbon clinchers for my Tri bike. I've used them for a couple of Sprint Tris and a couple of TTs. My initial concerns over the stability of the front (being narrower than what I am used to) have proven to be unfounded as I haven't noticed any real difference. In fact, the stability of the front is probably helped in cross-winds with the narrower tire (22 versus the 25 I had on). These are fast rolling, stable, and grippy. Get a pair to upgrade your TT setup.
Good tire, nice to have wider tire at 24mm and skinnier front at 22mm. The rear also has a harder rubber and lasts longer and and extra belt for puncture resistance. The front is softer for better steering. I can't understand why more manufacturers don't make rear / front specific tires it is a great idea from Conti!
I ride a number of centuries and club rides each summer and am a pretty aggressive rider. I've had a few pairs of these and have found them to be quite durable and puncture resistant. They roll nicely and I've never had a problem with grip on fast descents or in the wet. My only dislike would be that the rear wears out quicker than the front, which is typical - but these are sold as a set. Not much to be done about that, but it is what it is.
Hands down - the best set of tires for the money.
Terrific durability - great for the those hard training days and or racing. (especially if you live in an area prone to flats.
