Got errands, gear, or groceries to haul—but don’t want a full-on cargo bike? Meet the 4130 Cargo Fork, the perfect upgrade for your steel commuter or townie frame. Built from burly 4130 chromoly steel and ready to work, this fork transforms your standard setup into a utility beast, all while keeping your ride fun, fast, and functional.

Low Deck, High Versatility

The 4130 Cargo Fork uses a 20" front wheel to keep the load platform low and stable—ideal for carrying everything from crates of beer to your fur baby (just don’t forget the goggles). Lower center of gravity = better balance = more control when you're loaded up and rolling.

Built to Work

• Integrated Front Rack Platform: Bolt on whatever you want—milk crate, basket, pizza box, or your own custom setup.
• Flat Mount Disc Brake: Run modern braking systems for reliable stopping power.
• Thru-Axle Included: Boosted stability and stiffness.
• 160mm Rotor Compatible: Rotor included with Wheel Bundle.
• 1-1/8” Threadless Steerer: 300mm long to fit most modern steel bikes.

Optional Add-ons

• Front Wheel Bundle ($100): Includes all the essentials so you're ready to roll:
  • DM 32H Rim laced to sealed bearing hub with 12mm thru-axle (Schrader valve)
  • CST 20x2.125” Tires – wide and cushy for cargo duty
  • 160mm Rotor
• BRAKES:
  • Mechanical Disc Brake – $29.99
  • Cable-Actuated Hydraulic Brake – $49.99 (Either choice gives you powerful braking without the complexity.)
