600/650x19 Race Valved Inner Tube

A dedicated 600/650x19 size tube, by Blockley, with generous thickness which is the best tube you can buy. It is made from Butyl which is the best material that can be used for inner tubes. This version of our 600/650x19 tube has a metal nickel plated valve stem, as they were in period. You will find that for example a Michelin tube marked up with a 600x19 size will also be the same tube they supply for a 700x21 tyre! This is why Blockley has made this dedicated correct inner tube.

(£51.60 inc. vat)


Note this tube is not marked for 18" tyres as other brands. For 18" we have a different tube. This shows why there are so many actual Blockley tube sizes, rather than how the other suppliers do it - a few tubes with plenty of sizes written on them! We use this inner tube size with our Blockley 600x19 tyres (marked "550/600x19") and 650x19 tyres. It is also the tube that gets used in 700x19 tyres.

Remember if you have a tyre marked 550/600 it will be a 600x19, so this tube is what you are after.
