Spot Brand Ajax 55cm singlespeed belt drive urban bike, I am guessing it is a 2016 model. Measurements are top tube - 55cm C-C/Seat tube 50cm C-C and 55cm C-T. Bike only had 1 owner. Has a carbon fork, Shimano Alfine Crankset, Avid BB 5 calipers and levers, hammered fenders, brand new Bontrager saddle and grips, Sram X9 hubs laced to Velocity A23 rims, Continental tires. There is some slight corrosion on the fender and brake bolts, but nothing that affects the bike. Rides great, bearings are smooth. Overall, an amazing bike to commute around on.
