CRs:
On a whim, I had a look at the UK-based Prendas Ciclismo clothing store. There are new, modern (polyester) reproductions of classic jerseys available for purchase:
La Vie Claire, Salvarani, Z , Peugeot, Reynolds, Renault/Elf, Del Tongo/Colnago, BiC, Brooklyn.
Here's the link: http://www.prendas.co.uk/
No relation to seller.
