815x105 Inner Tube
Blockley 815x105 Beaded edge thick butyl inner tube with nickle plated metal stem, as they looked in period. It is really imperative that every beaded edge tyre has its own specific beaded edge tube, unlike what else has been pushed on people for decades by the Classic Wholesaler "experts". These people sell you the same tube marked up with a myriad of hugely differing sizes, and supply the same tube for whatever tyre you have ! And this is why Blockley has had to make tubes, doing it properly as it should be. We only make this tube because we make the tyre that it fits.
For interest, the Michelin 815x105 tube is marked up "935x135, 895x135, 880x120, 815x105", typical of what big companies do to save money and give their wholesaler agents big margins to sell this unsuitable stuff. But the agents are smart enough not to advertise the tubes like this. Alongside each tyre like 815x105 they would put a tube which they say is 815x105, not that this tube fits a colossal 935x135 also. . . Note that this is three very different sizes of tube, amalgamated in one which is why things don't work (while Blockley correctly make 3 tubes to cover one from a Michelin). Just imagine how much misery these Michelin tubes have caused people over the last few decades, the tube being about 1 ft. too long, which somehow gets shoved in, while their wholesaler agents persuade you that you need the best by charging a high price and hiding behind a brand name, the heavy weight of them because their tube is too big!
Blockley make one beaded edge tube per tyre because that is how it should be and that is how things were, but this costs so much more to do. In our case 3 times as much because Blockley is making 3 lots of tooling and carrying so much more stock compared to having one tube fitting too many tyre sizes, yet our Blockley tubes cost no more. And they cost no more because by selling direct no one is adding a big chunk on in between. This will give you a little insight into the rip off that is the Classic Vintage tyre, and tubes, market!
