As we reach day 10, we look at another one of the more unique builds this year. A custom Sarto Dinamica, with a sporty paint job and a stripped back drive train. While 1x builds are common place these days, it's not too often we get a request for a fully custom single speed. Built for equal performance on the road or the track, Dinamica is complete with a Sugino 75 Direct Drive crankset, gold Izumi chain, Phill Wood track hubs, and Enve 4.5 rims. Head to our original entry here for a download on the full specs and details.
