4130 All-Road - Root Beer - SRAM Rival AXS
FULLY WIRELESS STEEL GRAVEL
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 revamped 4130 Chromoly Steel frame with a fully wireless SRAM AXS drivetrain.
Choose Rival XPLR AXS for 13 speeds and a tighter gear progression, or Eagle Transmission "Mullet" AXS for 520% of range and a bailout gear that will get you up anything. Both come with Rival E1 carbon levers, hydraulic disc brakes, and a hangerless derailleur bolted straight through the frame — no cable to route, no housing to contaminate, no indexing that drifts out over a season of dust and grit.
Then build it your way: 700c or 650b, three fork options, and clearance for up to 700c x 55mm or 650b x 60mm. UDH, dropper-ready, and mounts for three bottles plus racks, fenders, and cargo.

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 double-butted 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.
- 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 — 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.

Choose Your Wheel Size — same frame, same clearance, two genuinely different bikes.
700c — Fast & Versatile
- 23mm tubeless-capable rims (tape, valves, and sealant required)
- Continental Terra Hardpack TR 50mm
- Best for: gravel racing, mixed-surface riding, fast days out
650b — Capable & Comfortable
- 25mm tubeless-capable rims (tape, valves, and sealant required)

- 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.

See full specs →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.

FAQ
Rider-owned in Phoenix, AZ since 2009. 5-year frame warranty on steel, aluminum & titanium · most in-stock bikes ship in 1 business day · 4.8/5 from 16,000+ reviews.
How does my bike show up, and do I need a shop?
That depends on how you order it:
- With Pro-Build (select models: $79.99, or $129.99 on Carbon Road). Our mechanics in Phoenix face the frame, set up and bleed the hydraulic brakes, index the drivetrain, cut the steerer to our stock length and torque-check everything before it goes in the box. That's the shop work that usually runs $150–$300 locally. You bolt on the bars, seatpost, front wheel and pedals, set your hoods and wrap your tape: about 20–30 minutes with a hex set and a torque wrench. Pro-Build adds a 1–2 week build queue.
- Without Pro-Build. Your bike ships mostly assembled, but it needs a full assembly and tune by a professional mechanic before it's ride-ready. Carbon, titanium and AXS builds that skip Pro-Build arrive unassembled with an uncut steerer, so your shop can build them to your exact fit.
Either way, a professional build is safer, rides better, and unlocks our better warranty tier (see below).
What does the warranty cover?
Every State bike comes with our Standard Limited Warranty against manufacturing defects for the original owner. No registration required.
- Steel, aluminum & titanium frames and forks: 5 years
- Carbon frames and forks: 1 year (2 years with ProBuild Advantage)
- Non-consumable parts (cranks, wheels, hubs, bars, stem, seatpost, pedals): 1 year
Not covered: wear items (tires, tubes, chains, brake pads, grips, bar tape, saddles, spokes, paint), rust on RAW finishes, crash damage, and labor or shipping costs. Full warranty details
What is ProBuild Advantage, and how do I get it?
It's our "you did it right" warranty tier for bikes that were professionally assembled and registered within 30 days of delivery. You get everything in the Standard warranty, plus:
- 2 years on carbon frames and forks, instead of 1
- Priority claim review: ProBuild claims go to the front of the line
- Faster help with shifting or braking issues, without the "did you tighten that bolt?" back-and-forth
- Shipping perks on approved warranty replacement parts
- Discounted pricing on a replacement frame or bike for up to 5 years from delivery, if a crash wins
To activate it: add Pro-Build when you order, or have a local shop assemble your bike and keep the receipt. Then register your bike within 30 days of delivery with your serial number (engraved under the bottom bracket shell) and proof of assembly. If you ordered Pro-Build, our mechanics already did the build. You just register.
When will my bike ship?
Most in-stock bikes ship within 1 business day, and you'll get tracking as soon as yours is on its way. Adding Pro-Build puts your bike in our build queue for 1–2 weeks before it ships. Shipping is calculated at checkout from your location and the size of your order, and bikes go out by UPS or FedEx Ground.
Outside the U.S.? We ship worldwide, and duties and taxes are paid at checkout, so nothing is due on delivery. Shipping policy
What if it's not right? Returns & exchanges
You have 30 days from delivery to request a return or exchange. Bikes need to be unused, in like-new condition and in their original packaging.
- Refunds: a return label fee is deducted ($45 for complete bikes), and original shipping isn't refundable.
- Exchanges: issued as store credit. The return label fee applies here too.
- Package Protection Plan (add it at checkout): covers loss and damage in transit, removes return label fees and deductions, and extends the window for exchanges and store credit to 60 days. Refunds stay at 30 days.
Pro-Build and other service work can't be refunded once it's done. Final sale, clearance and limited-run items can't be returned, and neither can international orders.
Can I pay over time, or use HSA/FSA funds?
Yes. Financing with Bread Pay splits your bike into monthly payments, and you can pay it off early with no penalty (subject to credit approval). You may also be able to use pre-tax HSA/FSA dollars through Truemed. A short intake at checkout checks your eligibility, which depends on your plan. HSA/FSA guide
Which size do I need?
Geometry charts, size guides and full build specs for every model are on our Size Charts & Specs page. Between sizes, or running a tall stack or long stem? Get in touch before you order. Pro-Build cuts the steerer to our stock length, and that can't be undone.
Can I see one in person or get it built locally?
Use our dealer & shop locator to find a shop near you for a look in person, assembly or a tune-up.
Something arrived damaged or missing?
Email info@statebicycle.com within 30 days of delivery with your order number and photos of the item, the box damage and the shipping label, and our team will take care of you. If a part has failed, submit a warranty claim. You can also reach us at 1-855-55-STATE or through our contact page.
