I got a account with Pro Accessories and they had nothing.
Saw that CST on ebay but but it would have been nice to not have to buy at retail level when it is for a customer.
Anyway Ron Angel Wholesale came to the rescue with a Duro in that same pattern as the CST. The sales rep says they are going to remain dedicated to bringing in older/odd ball tyres for this reason because they can be hard to get. I remember last time i had to get a tyre for this bike a number of years ago it was hard too. Back then a Kings was fitted. 19 inch classic pattern 3.50 fronts are much easier to get than 18.
