600/650x19 Race Valved Inner Tube

A metal stemmed thick butyl inner tube for 600 and 650 sizes of 19" tyres. 

(£44.40 inc. vat)


Note this tube is not marked for 18" as other brands. For 18" we have a different tube. This shows why there are so many actual Blockley tube sizes, rather than a few tubes with plenty of sizes written on them! You cannot buy a better tube.
