These replaced the venerable Continental GP 4000 SII on my bike. They grip and corner really well.

I wish the 25mm version was the same size as the 4000's as they were significantly bigger. Next tire purchase for me will be the 28mm size.

I was running the GP5000 clincher, Great in the dry, lightweight fast and grippy. you feel confident leaning onto corners, they ride smooth and give good braking traction.

They hold on to small road debris such as little pieces of glass, or sharp tiny rocks which lead to several cuts and pits in the tyre tread. The first time I got caught in the rain with these tyres the front punctured, at that point I had the tyre about 3 days, I'd only covered around 60 miles on them. Then around 300 miles, 3-4 weeks later, caught in the rain again, but this time it was terminal. The rubber on the rear tyre started to delaminate at one specific spot, exposing the casing underneath. Fortunately the tyre managed to make it home. Upon close inspection it appears that while riding water worked its way between the casing and the tyre tread via a small cut or pit in the rubber, ultimately causing it to separate. Excellent tyre, if you ride smooth clean dry roads. So, now I'm running Michelin Power Road.

Really low rolling resistance. Good puncture resistance, I used the tubeless version of these for the Bikingman Oman Race 2020, which included some really savage gravel riding sections and had no problems at all. Currently have clocked up over 1200 miles on them now, and have had to repair the rear tyre once owing to a shard of stone that had burrowed its way through. Tread wear indicators are showing plenty of tread left on the rear, so expecting to get a good life out of them.

They were very tight when fitting to mavic rims, hard to fit.
