7 speed Cassette identification help?

[Matt-k]

Can anybody shed any light on this, make/model? I picked it up at my lbs junk box and thought it looked quality.!
Thanks for any input! Constructive or not!

SRAM PG730. Probably. Stick it on Ebay for £40 because there is a shortage at the moment.

Possibly, I think the back looks different, this has the extra small cut outs, also it's missing the lock ring so could be missing smaller rings too I suppose? I'll have to look in the parts bin again!

Duh. It's probably a 9 speed PG-950 or alike then.

The 8 speed is PG-850, but since there could be two sprockets missing - the 12T and 11T I reckon it is a 9 speed.

You could measure and check the sprocket spacing according to St. Sheldon to confirm.

A trip back to the LBS & recovered the missing ring and lock ring, 8 speed!
