Nothing you can buy is as good as what Blockley makes. This tube is also suitable for fitting in the 700x20 Blockley tyre.

Because Butyl material is so good you will find butyl tubes are always too thin now, plus tubes are not made like they used to be, as Classic car owners have to take tubes which the big manufacturers say is fine to fit in too many tyre sizes . That is why we make tubes, to compliment the awesome quality of our Blockley tyres.
