This is a used Shimano Deore XT Linkglide M8130 rear mech.

It is only compatible with 11 speed Linkglide drivetrains. 

There are some cosmetic marks on the clutch housing and on the cage and parallelogram as you can see in the photos, some of which have been touched up.

The parallelogram pivots have play, but the indexing is just about ok. It's not perfect and so please consider it as for Spares / Repair.

The jockey wheels move freely. 

Thanks very much for looking. Please check out my ebay shop for loads more bike stuff.
