I have a 2014 Fuel EX7 that I purchased new last year(Leftover at LBS) paid $1,700.
I’ve been happy with it, rode well over 1,000 miles of singletrack on it since purchased and even competed in my first race(4th out of 16.)
It has been upgraded in the past year with the following:

-converted to 12x142 thru axle
-KS Eten-I dropper Post
-Answer Protaper SL carbon handlebar
-60mm Answer stem
-ODI Rogue Grips
-Specialized Phenom Expert Saddle
-Syncros XRRC Wheels (Rebadged DTSwiss Splines)
-54t star ratchet
-Forté Pisgah 2 tires 29x2.35 set up tubeless

I am at a point where I would like to upgrade to 1x drivetrain, possibly replace wheels with something wider(currently 19mm internal), full service rear shock,
Replace fork damper (fox quoted $100 part) and full fork service.

The alternative would be to either find another newer bike shop leftover or buy YT Jeffsy.

Any input would be appreciated.
