Mafia Bomma Traffic 27.5 - MidnightTraffic is the new benchmark 27. 5 geared street bike for those who demand an all round performer for combos and traffic work but find the 29 bikes just a little too big. . With an emphasis on buy it and ride it (no upgrades needed), We took our tried and tested geometry know how and packaged it into a lighter stiffer machine. We then wrapped that up in a selection of exciting new colourways to form the basis of your next individual creation.
