.........for Mrs A's ancient Raleigh Ebony. Thing is the tyres are completely shot. Bits of sidewall flaking here and there and I dare not pressurise them to their (once) optimum. She bought this relic back in 1987 and has used it since for foul weather rides and for going down the pub, but she still loves it. The snag is, I can't find any new tyres for it. They are 650 X 28A, (28-590 ETRTO system) and enquiries at various equally ancient bike shops have yielded responses from a straight no chance to bemused reminisces. Does anyone know where I might be able to obtain replacements?
