Came across these SA (I presume: ) internals recently. NOS in a greasy, polythene bag. (Good sign?)
Clearly been 'on the shelf' a while.
Madly perhaps, it came along with a fair 1985 531C Orbit Gold Medal machine off UK Ebay...
No labels/other info. No stampings to indicate anything.
I'm familiar with SA 3 & 4 speed internals, but this one I never saw before.
So, after some research, I think I've narrowed it down to S2C. But not sure...
Can anyone help nail it?
It is different from the current(?) S2C HSX157, but very similar, so could be an early version?
S2C introduced in 2010 I believe.
Bit of a mystery anyway, right now.
(I'm aware I might be totally wrong here! If it was a Sachs, for example: )
Can't use it if I can't find the right shell: )
I've ridden a small wheeler previously with the S2C set up & loved it, but I never saw the internals...
