I rather stupidly forgot to measure up the offsets before cutting out the hubs from the wheels of my '56 rigid and now can't find the right offsets for rebuilding. It has the 8" half-width front hub and riveted rear with taper rollers - draganfly refer as type 5 and 10.
I would rebuild the wheels so, that the centre of both the rims are exactly in line with the centre of the top frame tube (the one going from the top yoke to the sadle).
I did so and can drive my M20 hands free.
