Nothing serious. It's a Premium Broadway 20.75tt, stock 8" rise bars, stock stem, integrated headset, Alienation Deviant front rim laced to a Madera hub, stock cranks, Premium slim pc pedals, Profile 25t Imperial sprocket, kmc halflink, animal pivotal seat, Alienation Black Sheep rear wheel, maxxis dth front tire and a foldable Kink rear, and ODI grips. And that's about it! Love this bike, rides smooth, light, and has been insanely reliable! Just sharing my beater! Thanks for looking guys!
