These tires are really good at not puncturing and yet are reasonably light, have good grip in dry and wet, and roll well. Sure, you can race something lighter but for everyday riding, training, and commuting that is still fast and fun, these tires are perfect! Virtually as tough as gatorskins but much better in all other dimensions.
No cons - I've had several and continue to love them.
These are my go to tire. Love the 4000s which just retired and have the new 5000s. The 4000s sidewalls has a tendency to blow after so many miles though. These 4 season have good flat protection, good roll and great grip. Rode 4000s and dura skin for years. These are all I ride now. I put on 10000 miles or more a year between commuting and weekend rides and good wheel sets, tires and saddle make all the difference.
I ride gravel trails with the grand kids and occasionally commute on debris laden deteriorating city streets with inattentive drivers. Good side wall protection is a must and thus have avoided many opportunities for punctures. Adjust the air pressure to the terrain 40 - 55 lbs. and ride with confidence. I have not made a direct comparison with comparable Compass tires but I think they are close in speed and comfort - on sale well worth the price. Had been using 32 mm Gatorskins and these are better for all weather traction, comfort and speed. The black edition actually improves the appearance of my beater VO campeur. To sum up, A tire that does its job very well.
These tires are fantastic for commuting in the PNW. Lots of grip in the rain, fairly light and great durability. I got over 3k out of my rear tire going over rough roads and. lots of broken glass. Just picked up a new set on sale from Western. Great bike shop!
This is my second pair of these Grand Prix tires. They roll fast, come in several sizes and have fantastic flat protection. They are great for Spring and Fall conditions when the roads might be rather nasty. You might want to swap for something a bit lighter in the Summer.
I've used 28mm GP 4-Seasons tires for years - for winter training, commuting, touring, gravel, and on a tandem. I think of them as a tougher version of the 4000S. Great grip, durability, and puncture resistance. The black side walls on the Black Edition make 'em look a bit cooler than the old gum-wall version, too!
I usually ride Conti's 4000 Grand Prix in size 23 mm and purchased the Grand Prix 4 Season in 28mm for winter riding. Like the 4000 these are folding tires and are lighter than I thought. They corner well, and are more durable. I am a fan. Great success!
As a daily commuter in Seattle I needed tires that could withstand lots of road debris, wet weather, and plenty of hills. These check all those boxes. I've only had them a few months, so can't really judge them on how they wear and how much puncture protection they have. So far so good though.
In June I rode these tires (28mm) in the Haute Route Rockies - over 500 miles and 50,000 ft. of climbing on a mix of pavement and gravel. They were bullet proof and comfortable. No punctures, no problems. They performed flawlessly in heat, hail, rain and snow. They tracked with confidence on the descents and didn't hold me back on the endless climbs. I've also put countless training miles on these tires without a single flat. Pricey - maybe. Worth it - definitely.
