600/650x19 Extra Heavy Duty Reinforced Inner Tube
A super thick extra heavy duty Blockley tube marked 600/650x19. Something you would use when using a large tyre or on the Peking-Paris where you want something you could almost drive on without a tyre! This was whay we were asked to make them. A superb quality rubber valve stemmed thick butyl inner tube. A great product.
These inner tubes can fit in our Blockley 600x19 tyres (marked "550/600x19"), but are ideal for for the larger tyre sizes.
This is an even thicker heavy duty tube than our already plenty thick
standard tube. This heavy tube is ideal for very arduous conditions.
