Mafia Bomma Traffic – Grips Bikes

Mafia Bomma Traffic Blue

DESCRIPTION

Traffic 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.

Featuring Microshift 10-speed, Shimano Hydro (MT200), hollow tech sealed BB, hydro-formed 6061 alloy frame with CNC machined components and peg mounts as standard, SnakeskinS (Sticky) tyres and 27.5” alloy double wall rims. To name but a few of the impressive features.
