4130 All-Road - Raw Phosphate (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.
Build & Customize
Wheelset — choose your build
- 23mm tubeless-capable rims (tape, valves, and sealant required)
- Continental Terra Hardpack TR 50mm
- Best for: gravel racing, mixed-surface riding, fast days out
- 25mm tubeless-capable rims (tape, valves, and sealant required)
- Vittoria Barzo 2.1" knobby tires
- More volume, more grip, more trail capability
- Best for: bikepacking, rough terrain, off-road days
The Continental Terra Hardpack TR 50 scored 18.6 watts rolling resistance in independent lab testing at BicycleRollingResistance.com — earning a 4.5/5 "Highly Recommended" rating and putting it among the fastest gravel tires at this width. A flat central tread keeps things quick on pavement and hard-pack, while developed shoulder lugs and Continental's ShieldWall puncture protection handle the rough stuff. PureGrip compound means grip and durability don't get traded off against each other. At 50mm, this tire smooths out terrain that would rattle a narrower setup — without giving up speed.
Fork — choose your setup
- Matched to the frame — same ride character
- 12x100mm thru-axle
- Mounting points for racks and accessories
- Saves over 1.25 lbs vs steel fork
- Geometry-altering flip-chip for fit adjustment
- Improved comfort and front-end stiffness
- 40mm travel — takes the edge off rough terrain
- Noticeably smoother on chunky gravel and trails
- Regular MSRP $450
