The liquid sealant. Works quickly and reliably. Doc Blue repairs punctures in bicycle inner tubes, tubes, and tubeless systems. For repair or preventative puncture protection. Puncture repair fluids have been on the market for a while, but so far, none of these products have convinced us.

Doc Blue combines several principles, making it much more reliable. For tubeless systems and tubular tires, there's finally a simple and effective repair option. Dosage: approximately 50 ml per tire. For larger tires (57 mm or wider), increase the dosage to 75 ml. For road bike tires, 25 ml is sufficient. As a preventative puncture protection, Doc Blue is effective for approximately 3 months. A puncture is automatically sealed during the ride.
