4130 All-Road - Root Beer (12 Speed / UDH)
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.
