In a casual discussion with Derek Wheeler tonight about Walter Lisles and the Robey Tritandem, "Herts Wanderer", 45655/1930, I mentioned that we may need in the future to obtain new transmission chains for our Tri. Derek was telling me that there was a manufacturer in the USA. Further investigations on the internet have shown that this is correct and if anyone needs it, they can download a PDF catalogue from
www.renold.com
These chains were used amongst other things on Robey tandem rollers and Tritandems as well.
