Works quickly and reliably. Doc Blue seals holes in bicycle tubes, tubular tires or tubeless systems. For repair or preventive protection against punctures. Anti-puncture fluids have been around for a long time, but all previous approaches have failed to convince us. Doc Blue, on the other hand, combines different active ingredients and therefore works much more reliably. For tubeless systems and tube tires, there's finally a simple and effective repair option. 4. Dosage: approx. 50 ml per bicycle tire 5.
