Ahhhh, that rings a bell. There was a time I knew the distinction between tubular rims and wheels -- thank you so much for the clarification. Now with that decided, any preferences for tires?
There may be a lot about "BSA" on line. I think my friends BSA motorcycle was a "Lightning Twin" two cylinder.
That's a burly bike. I read somewhere that BSA equipped the British military with folding bikes in WW2.
