Rockshox SIDLuxe Select+ RL 190x45. Ran the serial number and found the tune info.See the third photo for tune info. Not sure what bike model it came off of. From what I was told these are new shocks that were removed from a new bikes because customers wanted different suspension. Shock stanchions are free and clear of any damage. Shock has standard eyelet mounts for whatever hardware you may need for your bike. All shock sales are final.
