“Our Most Capable Bike Ever.”
The 4130 All-Road Flat Bar in Rust Fade brings advanced gravel technology to riders at an unbeatable price. Built on a rugged 4130 Chromoly Steel frame and fork, this bike is ready for anything.

This Is The Tool For You If…
- You want a durable, steel gravel bike that can handle commuting, touring, and trails.

- You want the option to swap between wheel sizes (700c/650b) for different terrains.
Choose Your Adventure
Two Bikes in One
Customize your ride from the start. Choose 700c wheels with slick tires for efficient commuting and road riding, or go with 650b wheels with wider, knobby tires for off-road grip and cushioning. Want it all? Select “both” at checkout to receive a second wheelset complete with tires, tubes, rotors, and cassette for easy swapping.
Adventure Ready
Loaded for the Long Haul
The 4130 All-Road is built to carry. The frame features two water bottle mounts plus rear mounts for a rack and fenders. The fork comes standard with 5 sets of mounts for water bottles, accessories, fenders, or racks. Planning a massive tour? Upgrade to the Carbon Fiber “Monster Fork” for even more mounting options and weight savings.
