I have tried the ebikestop.com,and they do have the CR-18 26x1.3/8,but in order to ship them to Athens,they ask about 150$,plus the cost of the rims:so all together would cost around 210-220$ !!!!!!
Then I found the the AEBIKE.com,who have all sorts of the CR-18s,(36holes,32holes,40holes),but they don't ship overseas either.So I keep on trying.....
Strange thing is that it seems that the CR-18s(26x1.3/8),exist only in US shops....and nowhere in Europe!(A bike from Europe can find it's rims only in US!!!!!)
That makes me think that Raleighs and their genre are more appreciated,or exist in larger numbers over there, than here.
Anyway, I'd like to thank you for helping vohannrim,and I wish you better luck than mine..
