The 4130 Steel frameset in Matte Black / Mirror is a flat black frame and fork with the State script logo in a mirror finish. It is the same double butted chromoly frame and fork State builds its 4130 fixed gear and single speed bikes on, redesigned for bigger tires and given rack mounts on the fork and seat stays.
It comes as frame, fork, headset and seatpost clamp, ready for the rider's own wheels, drivetrain and cockpit.
Key Features
- Double butted 4130 chromoly. Frame and fork are both 4130 chromoly, double butted for strength without extra weight.
- Room for 45c tires. The wishbone rear clears 45c tires, and riders report fitting 50c and up.
- Built in chain tensioners. Horizontal dropouts with integrated tensioners keep the chain tight on a 1 speed build, fixed or freewheel.
- Rack and bottle mounts. Fork and seat stay rack mounts plus 2 bottle cage mounts let the frame carry a load.
- Six sizes. Frames from 46 to 62 cm cover riders from 5'3" to 6'7".

Questions
Is the fork included?
Yes. The frameset is the frame, a 4130 chromoly fork with a 1 1/8" steerer, the headset and the seatpost clamp.
Fixed gear or single speed?
Either. The horizontal dropouts take a fixed cog or a freewheel, and a flip flop hub gives both on one wheel.
What is needed to finish the build?
Wheels and tires, a crankset and bottom bracket, chain, cog or freewheel, handlebar, stem, seatpost, saddle, pedals and brakes.
