I picked up a 2013 Cali SL for cheap, like real cheap. It looks like it was not beaten but also hasn't been used in a few years. So i am looking for some advice on the restore.

Parts i know so far:
New tires, planning 29x2.3
New Chain
Removing front chain rings as well as derailleur and adding narrow wide for 1x
possible Fork rebuild? Not sure how, or how to tell that it needs done?
Brakes have no push in them at all, possibly no fluid?
Remote lockout for the fork is catching and does not work fluid.

I will Post a pic to give an idea of what it looks like now. Any help would be great!
