My new gravel bike = 650 wheels
 

New 650b gravel bike came in mail Friday spend Saturday building it up adjusting and replacing stuff 1st ride was 20 miles of mostly hard pack, some single track bike was great.
I debated for ever but went with the 650 as I wanted more options out on my travel and I really liked how it handled.
like an old school mtb pre suspension ripped down smooth single track.

Brand? Model? Details?

Looks like a Polygon with Sora shifting and cable post mount brakes...is that correct?

yes. Took 1/2 hr or so to build out box. More to fine tune.
