The best tube for size 33x5 available anywhere in the world.

We made this tube at the request of Richards Bros in Cardiff (wire wheel builders) who explained that there was not a correct dimensioned tube available to fit a 33x5 tyre, and everything they fitted was a multisized labelled "bodge". Because Blockley was making a 33x5 tyre we then embarked on making the usual Blockley quality tube to suit.
