This Blockley tube is thick, made from butyl and has the rubber valve stem. There is no better tube made, or available, than this Blockley tube.  We made this tube only because we needed a perfect quality tube to supply with the Blockley tyres we produce. Dont forget to use rim bands too . . .

We also have this tube available with a nickel plated metal stem.
