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

We made this inner 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", either too large or too small diameter. Because Blockley was making a 33x5 tyre we realised we needed to make a proper tube - this is the only tube that fit a 33x5 tyre as it should be, and with the usual Blockley quality to suit.
