current price, $999.99
The 4130 All-Road is built for riders who want to do everything — gravel races, bikepacking missions, commutes, trail days — without buying multiple bikes or compromising on any of them. A fully revamped 4130 Chromoly Steel frame with UDH compatibility, dropper-post readiness, semi-internal cable routing, and mounts for bottles, racks, fenders, and accessories gives you a platform that can be set up for almost anything.
Platform Highlights
- 4130 Chromoly Steel Frame — Tough, repairable, and with a ride quality that carbon can't replicate. Built for the long haul.
- UDH-Compatible — Universal Derailleur Hanger means no hunting for proprietary parts anywhere in the world.
- Dropper Post Ready — Internal routing already in place. Add a dropper whenever you're ready.
- Semi-Internal Cable Routing — Cleaner than fully external, easier to service than fully internal.
-
Tire Clearance — Plenty of room for real-world rubber in any configuration:
- Frame & Standard Fork: 700c x 55mm (2.25") or 650b x 60mm (2.4")
- Frame & Monster Fork (Carbon): 700c x 55mm (2.25") or 650b x 50mm (2.25")
- Mounts for Everything — 3 water bottle mounts plus rack, fender, and accessory mounts. Pack it up or strip it down.

⚠️ Raw Phosphate Finish — Steel Care
The Raw Phosphate colorway leaves the steel frame with a minimal protective coating — this is intentional, and part of what makes it look the way it does. Bare and lightly coated steel requires a bit more care than a painted frame.
To keep your frame in great shape:
- Dry the frame thoroughly after wet rides
- Apply a light coat of frame protection wax or oil periodically
- Store indoors or in a dry environment
- Inspect regularly for any surface rust — light surface rust can be treated early before it becomes structural
With basic care, a raw steel frame will last for decades and develop a natural patina over time.
