A customer left me with a Racing Speed rear wheel,

I forgot to take a photo of the whole wheel.
The customer says the freewheel body is slipping forward,
and the pawl spring appears to be either bent or broken—
it's definitely lying almost completely flat.
When the spring breaks, it usually snaps clean in half at the midpoint,
but

this time it had broken in a way I haven't seen very often.
Depending on how it breaks, sometimes just the strongest pawl barely catches on the hub's ratchet teeth,
and the bike manages to limp home under its own power in such cases.
But when that's not the case,
you end up with an ultra-lightweight drivetrain made of carbon or aluminum,
and you're left retracing the history of the bicycle.
