I managed to pick up an old road bike on gumtree and it was looking fairly sad. It was laden thick with black spray paint and I could hardly make out the pantographs. I have been stripping back numerous layers of paint ready for a respray and discovered underneath a 1979 francesco moser super prestige. I got it with two sets of wheels either mavic open 4cd clinchers or mavic cx18 tubs. Both are laced to campag record hubs. The tubs wheels are perfect but have no tyres and I wondered if someone could tell me what width of tyre I could put on it? I normally run 23mm tyres will they be ok on such narrow rims? I'd rather run them then the slightly worn clinchers.
