The 4130 All Road frameset in Schoolyard Yellow is a gloss golden yellow frame and fork with white STATE block letters on the down tube. It is State's double butted chromoly gravel frame and matching chromoly fork in its simplest form: UDH dropouts, thru axles front and rear, and cable routing that stays completely outside the frame.
It clears mountain bike tires in 650b or 700c, so one frame can be built for gravel, loaded bikepacking or commuting.
Key Features
- Double butted 4130 chromoly. Tube walls are thicker at the welded ends, where stress collects, and thinner through the middle.
- Completely external routing. Every cable runs outside the frame where it can be seen and adjusted, so the first build goes faster and a shift cable swap is a short job with a set of cutters.
- UDH dropouts. The Universal Derailleur Hanger is easy to replace at almost any shop, and it opens the frame to direct mount drivetrains.
- Mountain bike tire room. Clears 650b x 2.4" or 700c x 2.25". One frame can run 650b knobbies for dirt or a fast 700c setup for the commute.
- Calm geometry. A 450mm rear center on every size, a 70.5° to 71.5° head angle and a 75mm bottom bracket drop keep it tracking straight on loose ground and steady when loaded.

Questions
Is the fork included?
Yes. The frameset is the frame, a matching 4130 chromoly fork with 12x100mm thru axle dropouts and a 50mm offset, the headset, both thru axles, the UDH and the cable guides.
650b or 700c?
Either. The frame clears 650b x 2.4" or 700c x 2.25". State notes that actual fit varies with rim width and tire brand, since a tire on a wide rim measures wider than the same tire on a narrow one.
What does the frame weigh?
State does not publish a frame weight for this frameset.
What is needed to finish the build?
Wheels and tires, a 1x or 2x drivetrain, a crankset and bottom bracket for a 68mm BSA shell (square taper or external), flat mount disc brakes, handlebar, stem, a 27.2mm seatpost, saddle and pedals. State does not list a seatpost clamp in the box.
