Continental

I have been riding these for a year. I ride tubeless and have not had any issues with the flats or cuts. These are comfortable and last me about a year (3k miles). I have older carbon rims that are very difficult to break the bead from the rim in the field, so I can't ride recreationally with thinner tires because if there was a cut, I would be calling an uber.I can mount and remove at home using hand tools and an air canister, They are no more difficult to mount than the Maxxis tires I was using before. I have lost strength in my hands, and have found that I can reliably break the bead with 3 plastic woodworking clamps that have one foot handles, I put these about 4 inches apart, and by torquing all 3 at once, I can get the bead to move into the center channel in that spot, then use normal methods. I need a plastic bead jack to mount, and an air canister to get the bead seated.

The performance standard. I use these to race and train. Best ride quality for grip and smoothness. I'm using the recommended PSI from the Silca PSI calculator. Pretty good durability, I've had some holes that would not seal up with the orange seal I use, no fault of the sealant just too big of a cut. Bummer to replace a $90-100 tire from a puncture, but I have to consider all the smaller punctures that seal and I never know about, and the training miles I put on a race tire. Set up is easy using a floor pump on my Zipp wheels. I've tried many tires over my 54 years on this planet and keep going back to Conti GP's.

Why GP 5000? 1. Fast. Low rolling is far better than Vittoria or Schwalbe tires that I have ridden. 2. Punctures resistance. For such a high performance tire, it is incredibly durable. I never flat riding these tires. 3. Long lasting. Tire wear if less better than competitors. Worth spending a little more, a great value. 4. Grip. Most of my rides include significant descents often on wet roads. These tires corner extremely well on steep, technical descents. 5. Appearance. May not be important to some, but the cream side wall tire is beautiful on my bike. Highly recommend these tires!

Went from Terra Speed 40s to these. The Terra Competition feels better to me in just about every way. The only criticism I might have is that the tread on the corners seems like it ought to be a little taller, but in practice I haven't noticed these handling any worse on loose gravel. In fact quite the opposite, they seem to be better than the Terra Speeds on that stuff (though obviously not as good as the more trail-oriented Terra models). These roll better on tarmac than the Terra Speeds, and their puncture protection seems to be improved as well. Sizing is right on target as well -- they measure exactly 45mm when mounted to my DT GR1600 wheels at 36 psi.
