2014 Rockshox reverb 30.9 (external cable) 125mm drop

Hi all, I am selling my reverb to buy something with a longer drop. It is 30.9mm diameter and 380mm long x 125mm drop. It has no wear or marks to the stanchion part, and is perfectly smooth, however it does sag slightly (less than 1cm) if in the middle portion of the "travel". This issue is not present when the post is fully extended, and does not affect the main function at all as I usually have it fully extended or fully dropped.

It has not been serviced in the 6 months I have used it however it has been cleaned and lubricated after every ride, and has always been ridden with a dirt flap attached to keep all the mud off. (Dirt flap and saddle are not included)

Thanks for looking!
