All the answers to questions about delivery, payment, security, returns, warranty and much else.

I've always had Author tires on my bike, but I wanted to try a change.
Automatically translatedI don't ride it long distances yet, more around the city to get between my apartment, work, and smaller trips.
The material looks and feels high quality, I chose tires with a smooth pattern, suitable mainly for the city - not suitable for moderate or more difficult terrain (you should look at another type from Conti).
Please note, this type does not have a side reflective strip - only the types marked "Reflex" have it.
It works without any problems on dry surfaces, I haven't had the opportunity to test it in heavier rain yet.
Solid tire for everyday riding.
