State Bicycle Co. 4130 All-Road
Alpine Bloom. The Road Gets Better When It Stops Being a Road.
"Where Does the Pavement End? Let's Find Out."
Welcome to the adventure. The State 4130 All-Road in Alpine Bloom is built for riders who pack the night before — not because they had to, but because they couldn't wait to see where the road runs out. State's 4130 gravel bike is the ultimate do-it-all rig for riders who treat the map as a suggestion, built on a fully revamped, double-butted 4130 Chromoly Steel chassis with UDH dropouts, dropper post routing, and a mount for everything you need to go far.
Alpine Bloom is a colorway with intention — soft, electric, the kind of finish that belongs on a ridge at 6 AM and a coffee shop window at noon. The chromoly steel gravel bike underneath has the same range. Double-butted 4130 Chromoly naturally absorbs trail chatter that rattles aluminum frames, so mile 10 rides like mile 1, and mile 60 doesn't punish you for showing up. Under $1,000. Built to go everywhere. This is not a compromise. This is a decision that makes sense.
"The 4130 All-Road in Alpine Bloom is our answer to riders who are always looking for the next route. We spec'd double-butted 4130 Chromoly for its legendary fatigue resistance — it's designed to handle a lifetime of technical gravel without wearing down the rider who's pushing its limits. The Alpine Bloom finish is our nod to the early-season explorer who sees a distant ridge and points their front wheel at it."
THIS BIKE IS FOR YOU IF...
- You've had three bikepacking routes bookmarked for months. This is the bike that removes the last excuse.
- Your best rides start where the pavement ends. This one was built exactly for that moment.
- You want one bike capable enough for the Tuesday commute and the Saturday disappearance into the hills.
- You believe rack mounts, fender mounts, and dropper routing are requirements — not afterthoughts.
- You want a steel frame that will outlast the question of whether you made the right choice.
ONE BIKE. EVERY SURFACE.
The Platform That Goes Anywhere
The 4130 All-Road's strength is its adaptable platform. On 700c, it cuts through miles efficiently — fast enough on pavement, capable on hard pack gravel. On 650b, the character transforms: more volume, more grip, more capability on loose terrain and rough doubletrack.
Three water bottle mounts. Rack mounts front and rear. Fender mounts. Dropper post routing built into the frame before you even decide you want one. The UDH hanger means a replacement is available at any shop in any country. Every detail exists to reduce friction between you and a long day out.
THE DRIVETRAIN THAT GOES THE DISTANCE
The Gear for Every Grade
The 4130 All-Road is equipped with a 1x12 drivetrain — a 40t direct mount chainring paired with an 11-46t cassette. It has the climbing range to grind up a loaded ascent and the high gears to push pace on fast paved sections. No front derailleur. No split-second decisions mid-climb.
Simple, reliable, and capable for any terrain the Alpine Bloom takes you to. Click down for the climb. Click up for the descent. Get back to riding.
*Note: The 4130 All-Road arrives equipped with your choice of either the fast-rolling 700c or the high-volume 650b wheelset.
PREMIUM COMPONENTS
4130 Chromoly Steel
A fully revamped double-butted steel frame. Thicker at the joints, lighter in the middle — tough where it counts and lively everywhere else.
12-Speed Drivetrain
The State Bicycle Co. All-Road 1x12 drivetrain with an 11-46t cassette provides the range to conquer any gradient from flat roads to steep gravel climbs.
Massive Tire Clearance
Fit up to 55mm tires on 700c or 2.4" on 650b. Two completely different rides in one frame, without compromise in either direction.
Hydraulic Disc Brakes
Hydro-Mechanical calipers with 160mm rotors deliver consistent stopping power in any weather — field-serviceable and reliable over long days.
UDH Compatible
The Universal Derailleur Hanger means a replacement is available at any shop worldwide and ensures compatibility with next-generation drivetrains.
Abundant Mounting Points
Three bottle mounts, rack mounts front and rear, fender mounts, and accessory mounts. Designed from the start to carry what you need for however far you want to go.
WHY THIS BUILD MATTERS
12-Speed Dynamic Range
The State 1x12 drivetrain with 11-46T cassette gives explosive off-the-line speed and the climbing gears to conquer technical inclines — fully loaded or not.
Double-Butted Resilience
Double-butted 4130 Chromoly is thicker at the joints and thinner in the center — an industrial chassis that is exceptionally light and dampens trail chatter all day long.
Explorer Ready
Rack mounts, dropper routing, three bottle mounts, and massive tire clearance. The 4130 All-Road transforms easily into a high-speed touring rig for multi-day missions.

Frequently Asked Questions
How does the 4130 All-Road handle rough gravel and technical terrain?
The double-butted 4130 Chromoly frame naturally absorbs high-frequency vibrations before they reach your hands and lower back. Combined with massive tire clearance (up to 55mm on 700c, 2.4" on 650b), the Alpine Bloom provides a plush, controlled ride on chunky gravel and rough doubletrack.
What does UDH compatibility mean for the 4130 All-Road?
The Universal Derailleur Hanger means a replacement is available at virtually any bike shop worldwide — critical for long tours and remote riding. It also ensures full compatibility with next-generation drivetrains whenever you decide to upgrade.
Does the frame support both 700c and 650b?
Yes — the frame geometry is designed to accommodate both wheel sizes without compromise. When you order, you select which wheelset you want: 700c with up to 55mm tires for speed on pavement and hardpack, or 650b with up to 2.4" tires for aggressive off-road traction. The bike ships with your chosen wheelset.
Is the 4130 All-Road Alpine Bloom suitable for bikepacking?
Yes — it is one of the best platforms at this price for it. Three water bottle mounts, front and rear rack mounts, fender mounts, and dropper post routing already built in. The UDH hanger means service is available anywhere. Add a frame bag, handlebar roll, and saddle bag and you have a capable multi-day setup.
Does the frame support a dropper post?
Yes. Internal dropper post routing is already built into the frame. When you're ready, adding a dropper is a cable run and a post swap — no frame modification required.
Does the 4130 All-Road require professional assembly?
To validate the 5-year frame warranty and ensure optimal mechanical safety, State Bicycle Co. requires proof of professional assembly by a certified bicycle mechanic.
