Interesting how owners will go on and on about how much they loved riding their bikes, then you look at the chainrings and wonder "How many miles was that?" I bought a similar Raleigh International about a decade ago and the tiny wear lines on the bearings once I got them apart reaffirmed that the bike had maybe a hundred miles on it since 1974, yet the OO made it sound like he had ridden it across the country.

This PX 10LE would have come with tubulars, so the original owner must have had the hubs relaced with clinchers. Not at all uncommon in those days when 700C was just arriving on the US shores.
