Description
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 double-butted 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
- Double-Butted 4130 Chromoly Steel Frame — Thicker tube walls at the ends where they’re welded and stress concentrates, thinner through the middle where they don’t need to be. Strength where it matters, weight shed everywhere else. 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 (2.2″) 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.

The 700c tire: one of the fastest-rolling 50mm gravel tires you can buy.
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.

Top Pick

Zipp 303 XPLR S
- 700c only. UD carbon, hookless, tubeless
- 32mm internal / 54mm rim depth
- Built around the gravel tire first, not a repurposed road rim — lets you run lower pressure without the tire squirming in corners
- Wide, deep profile designed to cut real aero drag at gravel race speeds
+$1,000.00 (MSRP $1,500.00 – save $500)
SRAM engineered the 303 XPLR platform around the gravel tire first — wide, deep, and hookless — instead of just widening a road rim. The result: lower tire pressure without the squirm, more cornering grip, and real aero gains once you’re moving at gravel race speed.
— As tested by BikeRadar & Cyclingnews
⚠️ The Zipp 303 XPLR S uses hookless rims: tubeless tires only, 50 psi maximum, and approved tires only. The stock Continental Terra Hardpack TR 50mm falls within the rim’s 40–61c range. Check Zipp’s current approved hookless tire list before fitting anything else.
