I've been into a few bike shops including Condor, Cavendish and a couple others, none of which knew anything about the 25c Rando's. They've also commented that Vittoria have no official UK distributor and are possibility the least reliable brand around, so could be a very long time before we see them being stocked anywhere in the UK!
P.S. There will only be the 25c, as the 23c don't exist!
What manner of horseshit is this?
Vittoria make fantastic tyres and their own website seems to indicate a UK distributor..

I've never struggled to get hold of them from loads of retailers.
