Schwalbe Doc Blue Professional Puncture Protection Liquid 500ml

Now even better formulated for Tubeless conversions. It can also be used as a puncture protection preventative for bicycle tubes, tubular tires and standard Tubeless systems. Works fast and reliably. Doc Blue seals holes in tubes, tubulars or tubeless systems. Use for repair or preventing punctures. Puncture protection liquids have been around for a long time, but all existing products were unable to meet Schwalbe's demanding standards. Doc Blue combines several different principles and is therefore much more effective.
