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. This build pairs that fully revamped 4130 Chromoly Steel frame with a fully wireless SRAM AXS drivetrain.

No cables. No housing. No indexing that drifts out over a season of dust and grit.

Platform Highlights

• Fully Wireless SRAM AXS — Your choice of two drivetrains, both with Rival E1 carbon levers and hydraulic disc brakes. Battery and charger included.
• 4130 Chromoly Steel Frame — Tough, repairable, and with a ride quality that carbon can't replicate. Built for the long haul.
• UDH-Compatible — Required for the hangerless Full Mount derailleurs, and it means no hunting for proprietary hangers 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. With AXS there's far less to route in the first place.
• Tire Clearance — Plenty of room for real-world rubber in any configuration:
  • Frame & Standard Fork: 700c x 55mm (2.2") or 650b x 60mm (2.4")
  • Frame & Monster Fork (Carbon): 700c x 55mm (2.2") or 650b x 55mm (2.2")
• Mounts for Everything — 3 water bottle mounts plus rack, fender, and accessory mounts. Pack it up or strip it down.

Why wireless on a gravel bike

Electronic shifting usually gets sold on speed. On a bike that lives in dust, mud, and grit, it's worth having for a duller reason: nothing about it degrades between services.

Cable housing contaminates. Cables stretch. Indexing drifts. The shift you had in March isn't the shift you have in August. A wireless derailleur moves to a position it already knows, every time, regardless of what the bike has been through — and both of these derailleurs bolt through the frame with no hanger to bend and no limit screws to set.
