There is no better tube available anywhere, which is why we have made these "Blockley Superior" quality tubes. Far thicker and heavy duty than anything else, and made fom the best material butyl. This tube is fitted with a metal nickel plated stem. This inner tube fits our 30x3 1/2 tyre, and have dimensions that are correct and quite different to other tubes available.

With the thicker walls, and being made from the best material butyl, this will ensure the tubes do not lose pressure like the other tubes available - which is important because beaded edge / clincher tyres need to be run at higher pressure, because running on low pressure leads to problems and tyre damage. All valve stems we have seen from the period are nickel plated, which is why the Blockley tube valve stems are also nickel plated. These are a tube the likes of which customers have never seen before. These tubes cost much less than a branded Michelin tube because we sell them direct, and when you see these Blockley inner tubes you will know why you should have them, and why we needed to make them for our 30x3 1/2 Blockley tyres!
