The Metropolis 1 features loads of great parts mounted on a multi-butted NS cromoly frame. There big change in our flagship dirt bike for 2013 is the Rock Shox Argyle up front that puts this bike in another league. On top of that we spec'd our FMB tour winning Proof handlebars, lightweight tires from Kenda, sealed bearing hubs by Octane One, a microdrive 25:11 drive-train, fat integrated seatpost-combo and many more cool features.
