That would get me 70 gear inches for pavement, 60 gear inches for fixed on gravel, and 57 and 50-ish gear inches freewheel settings for dirt and single-track, without derailleurs or cross-chaining. I'll start out running 35 mm Continental Cyclo Cross tires, but the beauty of this era Raleigh Competition is they have gobs of tire clearance, more so than the Mercian above.

Now to get some rims and build up the wheels ...
