Rear derailleur is SRAM 10-speed with text "Blackbox Ceramic Bearings" and "Exact Actuation" on outer cage. Looks like 11 teeth on top and bottom pulleys. Bike approximately 2011. Is this compatible? Thanks

If you have the Black Box pulleys, chances are you will need the pulleys for either the XX or X0 rear derailleur.
