SRAM X0 Rear Derailleur, 9 Speed, Blackbox Carbon, Mid Cage, XO.

In good usable, working condition. Still useable when taken off bike but I've noticed that jockey wheels (cheap $20 part) need to be replaced for optimal performance - one is cracked, one has worn teeth. Hence price reflects this.

Some scuffs from moderate use. Pics will describe condition.

Worldwide postage.
