This is a custom build I did for a customer a few years ago. 49 cm all city nature boy with custom built velocity deep v rims on all city hubs. Rear hub is a flip-flop so you can go fixed or freewheel. Break set is tetra the stem a dead element and the bars are FSA. This was built up as his fixie/ commuter bike and spent the last couple of years on an indoor trainer with relatively low use. Easy swap to drops if you want to run this as your single speed Crossbike.
