A Blockley butyl inner tube suitable for tyre sizes 175 and 185R16

We produce this inner tube because we make a 185VR16 tyre and need a good quality wholesome tube to suit.

In addition for the 185VR16 tyre we also make an even thicker "600/650x16" tube which many like, which is available with a rubber stem as well as a nickel plated metal "race" stem.
