Shimano Lark black (1st style)

Shimano Lark black derailleur (1st style) main image

The Shimano Lark is a Skylark with the cable clamp bolt mounted on a sprung ‘cable saver’ arm. I have always liked this feature as it gives a pleasant supple feel to the gear change.

I think this example is the first version with the aluminium(?) nameplate and screw pulley cage stop.
