The 4130 Steel Line earned its namesake from the double-butted 4130-grade chromoly steel used on the frame and fork that maximizes strength without making compromises on weight. Internal cable routing, seat stay rack mounts, water bottle cage mounts, a flip-flop hub, and integrated chain tensioners provide versatility while maintaining the clean aesthetic State Bicycle Co. is known for. Drilled high-flange hubs, an open faceplate stem, and the CNC’d seat post clamp not only look great but also help to shave some additional weight.


The latest 4130 Steel Line models feature a subtle but stylish ‘STATE’ logo on the down tube and an updated ‘SBC’ head tube logo.
