4130 All-Road - Frame & Fork Set (UDH) - Raw Phosphate
Our versatile steel workhorse
Sold Out - current price, $479.99
Get ready to conquer the road less traveled. The double-butted 4130 chromoly All-Road frameset is now more versatile than ever, featuring key upgrades to enhance your riding experience. With Universal Derailleur Hanger (UDH) compatibility, dropper post readiness, and semi-internal cable routing, it’s built for adaptability. Whether you're hitting the gravel, tackling a bikepacking adventure, or commuting in style, this frame has you covered.
Double-butted means the tube walls are thicker at the ends, where they're welded and where stress concentrates, and thinner through the middle, where they don't need to be. You get the strength where it matters and shed weight everywhere else — which is what separates a good steel frame from a heavy one.
What's New?
- Wider Tire Clearance: Fit up to 2.4” tires with 650b wheels for even more off-road capability.
- Added Mounting Points: Bring along everything you need, from bikepacking gear to commuter essentials.

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.
Customer Reviews
I ordered this frame and fork on a whim, to build a budget single speed gravel grinder. Upon receiving it and measuring the frame, I was skeptical the large was going to be large enough, however, I was assured by State Bike Co it would fit me at 6ft 1in, and it does. I built the frame with spare parts I had laying around, and some new ones like wheels, crank and brakes. I will say, coming in at 24lbs or so, it is a fun bike to thrash around town on. All the braze ons will benefit when fixing racks for touring, and I can easily swap on a bar end shifter and some gears when needed. If I am asked, would I recommend this product? Yes, I would and I have.
I rode the V1 4130 for a few years and really fell in love. The bikes over deliver for the price every time for me. The udh internal routing and extra mount points were all perfect upgrades to an already great frame. I would argue that the clearance is exactly the same to the first though even though it’s now marketed as 2.4 on this version and only 2.1 on the last. I ran 2.4 on the V1 and it had the same amount of clearance as I do now on the the V2 with same wheel and tire set up. Was hoping to push a 2.5+ but there is no way it’s going past 2.4
Paint is very nice, frame is well put together. Just a few issues. Some of the grommets for internal cable routing were difficult to remove. The UDH that came with the bike was bent during shipping, making it unusable.
Bought this raw phospate frame to build up an allroad adventure rig. It looks really nice with a glossed raw finish with nice touches with gold welds and patina. It's a little bit of a boat but it'll be okay for mucking around town and getting off road if needed. For the price you get a nicely built, sturdy, steel frame that looks just as nice, if not better than a lot of pricier ones. It's got plenty of bosses to add racks and what not but it's already pretty heavy so I kept it only to one front portuer rack for now. For a cruiser the steel fork looks and works fine, but I think if you're looking to use it for more serious riding you might want to get the carbon fork to cut the weight. Mine is at 27 lbs but it rides nice and smooth.
I have had my 4130(L) for almost a year and have put almost 2k miles on it. The lilac is a great colorway and really pops with an all black component scheme. My only real complaint is that I wish the steerer tube on the fork was longer from factory so as to have a taller stack as I like a mix of upright and "aero" positioning but I have made it work with some higher rise bars. I am on the tall end of the sizing at 6'5", I run 27.5 wheels with a 1x 10-11-48 setup and it is my everyday all use bike from the grocery store to climbing a mountain. It feels great climbing and is super stable flying downhill. I am really glad I bought this frame and hope to enjoy many more miles on it.

My initial review of this bicycle frame, the quality of work from State Bicycle Company looks to be of very high, the braze joints are sound and the finished painted surfaces is beautiful. I am looking forward to building up a most unique bike from the frame.
The frame was delivered within and well packaged. Frame & additional parts were properly packed. I am very pleased with the quick shipping items in the package were protected. The frame is beautiful as expected
Replacement for the old 4130 frame. Excellent!
Pristine, brand new and mine to build, this frame looks great, very nice paint, and the build quality seems to be very good. Fork has lots of mounts, This will be a gorgeous bike.
