A month ago I purchased a new Stevens San Remo road bike, so far I'm happy with it but today I punctured both tyres.

I was about 12 kilometers into a ride when I rode over some rubber (about an inch high) which had been used to fill a crack in the cycle path, surely this should not be enough to puncture 2 tyres which have only ridden 300 kilometers in total.

I pushed my thumb into the rubber and it didn't seem particularly hard, a few other people went over the rubber on e-bikes and didn't get punctures.

Has anybody heard of problems with the Continental Grand Sport Race Tyres? Are race tyres unsuitable for riding on normal roads and cycle paths where hitting the odd bump or crack is unavoidable?

Cheers
