Created my first gravel bike

I regularly mountain bike and this is my first gravel bike that I built. Started with a 56cm 2019-2020? Marin Four corners elite frame. Could not locate an original Marin fork, so I paired it with a Surly Midnight Special fork. Sram Apex Eagle drivetrain (11-50 cassette, 34T front oval) and brakes. Rear Post mount to flat brake adapter did not fit good enough to make the brake line up,  replaced it with a post mount brake. Ritchey VentureMax XL bars 52cm. Panaracer 700×45 Gravel king SS + tires. 

Overall rides well, and still dialing in my fit. First all steel bike and impressed with the ride quality. I like that I can ride from home to the trails and do climbs in between because of my mountain bike type gear ratios
