Sounds lovely.


The only wrench in the machinery is that it has rear-facing
dropouts, and the o-bolts to grab the rear wheel axle to
tighten the chain were missing. If it ever had any! Or were
they always there on such bikes?

I think such, now exotic spare parts can be difficult to
find... Can you get away without them?

Chain tensioners are handy on roadsters to get the wheel
centered what with full mudguards, chain case, stirrup brake
and so on before tightening the axle nuts. They are not
necessary by any means and in fact the #1 problem with them is
riders setting chain tension too high which causes excessive
chain and bearing wear.

A QR holds as tight or tighter than axle nuts but either are
adequate especially on single speed where the gearing is not as
low as touring setups. Racing rules for track prohibit QR. That
and tradition are why real track bikes use solid axles. (My own
fixie is QR, never posed any problem whatsoever))

Mine too, also with zero problems.
