4130 Trail - Mountain Bike - Hammered Tobacco Powdercoat - SRAM Eagle AXS
A Powder Coat That Takes a Beating
Hammered Tobacco isn't paint. It's a textured powder coat — applied dry, then oven-cured into a shell that's thicker and far tougher than any liquid finish. The hammered texture earns its keep twice over: deep metallic flake that shifts warm and bronze in direct sun, and a broken-up surface that swallows the scuffs and trail rash that would show as bright scratches on a gloss frame. It's a finish designed to look better dirty — which is convenient, because this is a bike you're going to get dirty.
Underneath it, nothing left to knock out of adjustment. The 4130 Trail with SRAM Eagle Transmission bolts the derailleur straight through the frame — no hanger to bend, no limit screws to set, no cable to stretch. Wireless shifting that completes under full power, standing, mid-climb, and 520% of range from a 10–52t cassette. Double-butted 4130 chromoly, RockShox Psylo Silver RC with 35mm stanchions, and progressive trail geometry BIKE Magazine said “has no business being under $2,000.” Battery and charger included.

Tough as nails, now with no hanger and no cables. The State Bicycle Co. 4130 Trail with SRAM Eagle Transmission takes our no-BS steel trail machine and gives it the drivetrain that stopped being a wear item. Wireless shifting that completes under full power, a derailleur bolted straight to the frame, and 520% of range from a 10–52t cassette.

Why Transmission changes things
There's no derailleur hanger. A hanger is a deliberately soft piece of aluminum designed to bend before your frame does — good in a crash, bad every other day. Hangers bend a little every time the bike falls over, gets loaded in a truck, or catches a rock, and a hanger a degree out of true makes a perfectly good drivetrain shift badly.
The S1000 derailleur clamps directly around the rear axle through the frame's UDH dropout, referencing the frame itself instead of a sacrificial tab. Trail hits, transport, a bike that shifted in the back of the truck — none of it moves this out of alignment. And there's no hanger alignment to check, ever, because there's no hanger.
There are no limit screws. None. The mounting interface guarantees position, so setup is a short printed procedure you follow once using the marked Setup Cog on the cassette. No B-gap. No indexing to chase across a season.
It shifts under full power. The derailleur's firmware knows the physical geometry of the cassette — where every tooth sits and where in the chain's rotation each cog is ready to receive it — so it times the shift instead of just moving sideways and hoping. Standing, mid-climb, out of a corner: the shift you'd normally back off for is just a shift.
520% of range
The XS-1270 cassette runs 10–52t. That's 520% of range from a single ring — a top gear for fire roads and flat transfers, and a 52-tooth bailout that turns a steep, loose, technical climb from a hike-a-bike into a ride.
And it mounts to a standard HG freehub. Every other Eagle Transmission cassette requires an XD driver body, which usually means buying a driver — or a whole rear wheel — on top of the drivetrain. SRAM built the XS-1270 to fit the splined HG freehub that's been on mountain bikes for two decades. It's rated for aluminum and steel drivers, and approved for e-MTB duty.
Gears 8 through 12 also come off as a replaceable cluster rather than being pinned permanently into the stack — so when the climbing cogs wear out, you replace that section instead of the whole cassette.
Choose Your Fork
This is the biggest decision on the page, and it changes far more than weight. Going rigid doesn't just delete the squish — it turns the 4130 Trail into a different category of bike. Read the handling note below the cards before you pick.
RockShox Psylo Silver RC — 130mm
This is the trail bike. 130mm of travel, 35mm uppers, a Motion Control damper and a Solo Air spring — at this price you'd normally get spindly stanchions and a shrug of a damper. Keeps the slack 65° front end that lets you point it down steep, chunky, rooted ground and stay off the brakes. Pair it with Transmission and nothing on this bike is a wear item you have to think about.
- Travel: 130mm
- Axle-to-crown: 550mm
- Offset: 44mm
- Steerer: Tapered 1-1/8" to 1.5"
- Weight: 5 lb 12 oz
- Mounts: None
Carbon Rigid Fork
This is the one that transforms the bike. 563 grams takes more than four pounds off the front end — you feel it the instant you lift the front wheel, and on every climb after. Carbon damps the high-frequency buzz that makes rigid forks tiring on hardpack. Combined with the shorter axle-to-crown, it's the fastest, liveliest version of this bike: a genuine all-terrain machine for dirt roads, bikepacking, and big mixed-surface days.
- Axle-to-crown: 495mm
- Offset: 49mm
- Steerer: Tapered 1-1/8" to 1.5"
- Weight: 563g (1 lb 6 oz with axle)
- Mounts: 3 cargo per leg · rack (no fender mounts)
- Standard: ISO 4210-M passed
$100 less than suspension · 4 lb 6 oz lighter
4130 Chromoly Rigid Fork
This turns the Trail into a loaded ATB. Five cargo mounts per leg plus fender and rack mounts — more places to bolt gear than any fork we make. The shorter axle-to-crown drops the front end, so the bike sits lower and steers quicker: a dirt-road and bikepacking machine that still holds its own on singletrack. Steel takes abuse, shrugs off a scratch, costs the least to replace, and never needs a service.
- Axle-to-crown: 492mm
- Offset: 50mm
- Steerer: Straight 1-1/8" (30mm cone included)
- Weight: 4 lb 0 oz
- Mounts: 5 cargo per leg · fender · rack
- Rider limit: 120kg
$300 less than suspension · 1 lb 12 oz lighter
For riders who already have a fork they love, or who are building something specific. You get the complete Transmission bike, fully specced, minus the fork and headset crown race. Everything else is identical.
- Head tube: Tapered
- Front hub spacing: 15 x 110mm Boost
- Designed around: 550mm axle-to-crown
- Brakes: 180mm rotor — check your fork's mount
- Not included: Fork, thru-axle, crown race
$400 less than suspension
What you get is not a trail bike with the suspension taken off. It's a different bike: lighter, quicker-steering, and far more efficient everywhere that isn't a steep technical descent — dirt roads, doubletrack, bikepacking routes, hardpack singletrack, and the commute in between. That's an all-terrain bike, and it's exactly what these forks are for.
Pick suspension if you ride rough, steep, technical ground and want the slack 65° geometry the reviews above describe. Pick rigid if you want a fast, light, go-anywhere bike that you'll ride further than you meant to.
Both rigid forks ship with a 300mm uncut steerer and a 15 x 110mm thru-axle. The steel fork also includes the 30mm cone it needs to fit the tapered head tube, and a 180mm brake adaptor.
Quick Features
- SRAM Eagle Transmission, Wireless: S1000 T-Type derailleur, XS-1270 10–52t cassette, AXS Pod controller. Battery and charger included.
- Progressive Trail Geometry: A slack 65° head angle, low-slung top tube, and long front-center keep things stable when the trail gets rowdy while maintaining playful agility in the corners.

- Anti-fatigue geometry for long days
- The upgrade you feel on every ride, not just the rough ones
The AXS Pod
Shifting happens through a single handlebar-mounted pod rather than a cable-actuated trigger shifter. Two paddles, and you can reassign what each one does in the SRAM AXS app — upshift, downshift, or set it up however your thumbs prefer.
The app also shows battery level, pushes firmware updates, and handles service reminders. Pairing takes about a minute and doesn't require the app at all if you'd rather skip it.
Batteries
Battery and charger are included. The rechargeable AXS battery is the same one used across SRAM's entire wireless range, so a spare from another bike drops straight in. It swaps in about five seconds with no tools — worth carrying one on long days.
The Pod runs a separate coin cell that lasts years, not rides.

Customer Reviews
This is a great riding frame. I buy myself a hardtail frame every year and move as many components over as I can, then buy the rest. Mine looks darker than the picture I saw when I ordered it, but great finish. I went from riding an aluminum hardtail with similar geometry to this one and it almost feels like I have a short travel rear shock. Very nice feel. I did have an issue with my Maxxis Minion 2.5s rubbing the left side of the yoke (I think that's what they call it where the stays connect to the seat tube). The tire only rubbed when I pedaled hard or put extra weight on the rear. I was able to dish my wheel over a little toward the drive side and now it's okay but I did eat through the paint to bare metal, so my next tires will be 2.4s max. Frame does not include a chain stay protector. Like a noob, I realized this when my chain was clanking around and took a bite out of my paint. I immediately bought an Amazon special peel n stick and fixed it. I think State Bicycle should make their own because I am sure it would look better with their bikes. Everything went together well. Bottom bracket threads were clean and confirmed 73mm and standard threads. The 44/44 (straight tube) headset gave me a little trouble, but I finally got it to seat nice and straight; the crown race included is a cheap one with a slit in it; I used the cane creek one I had on my fork already and it worked with the headset. I replaced the included QR seat post clamp with a NQR one but the one included was fine. Great ride. Climbs as well as it descends, maybe even better. Very easy pedal compared to my previous 29er with most of the same components. The cable guides under the top tube are the screw-in clamp-style kind are a bit fussy, and my brake hose seemed too large for them to clamp it nicely, but they work. The threaded holes for the chainring guard and the brake post mounts had a bit of paint that needed to be cleaned out, but I got done in a couple of minutes. This is my 3rd State Bicycle and my favorite as far as style and ride. Great quality. Very pleased.
Hear me, riders of mud and misery
I sing of a frame forged in chromoly fire,
The Trail 4130, breaker of chains (emotional ones),
Crusher of roots, derailleur of doubt.
Not carbon-frail nor alloy-aloof,
This steely steed stays true when others fail
It flexes where it counts,
Takes hits without losing its headtube,
And never ghosts you mid-ride like a flaky dropout.
Yes, it’s heavy
But so is destiny.
Besides, true strength comes from carrying your own weight…
And sometimes your buddy’s spare tube.
It climbs with stubborn grit,
Descends like a headbanging demon,
And tracks straighter than your excuses for skipping leg day.
O Trail 4130, patron saint of hardtails and hard times,
You keep my wheels turning when my motivation flats.
May my chain stay strong,
My brakes stay true,
And my courage never need truing.
Ride it till the spokes of fate sing
For this frame does not crack…
It only creaks ominously.
(This thing is dope AF! I am 6'2" and I run a 175mm dropper. I ordered the M/L and it is perfect. The insertion for the dropper is maxed out and somehow it fits me perfectly!!!) If you have doubts, cast them out.
I picked up a frame only in large (6’0 tall) to replace an old niner air 9. That thing was 12 years old with geometry to match. I dabble in mtb/xc races, so i like fast, light, stiff bikes for the most part. Something about the niner with the steel head tube angle, 100mm fork, rigid post and aluminum really just combo beat the crap out of me, along with having a tendency to put me over the bars. Admittedly, I’m not the best mountain bike handler (keep me on the cross course!)
Anyway, i knew i needed a change. I looked at a few options. Knew i wanted to be at least somewhat singlespeed capable. I initially, that eliminated this one. Looked at some other bikes. Nothing really what i wanted for the price i wanted to pay.
Picked one of these up. Used an origin 8 revolver eccentric bottom bracket for bsa threads. That was enough to get me rolling. Raced it once. Ridden it a few times. It’s immensely more stable and feels far less scary than the niner. Took it down powerline out in Leadville yesterday and I’m still alive to write this review.
It isn’t as stiff or as fast uphill as the niner was, and is a bit heavier, but so far being less scared, and also staying ON the bike (instead of getting dumped off it) ends up being faster in the long run. I love it. Will keep at it.
I work at a shop that deals in State bikes, so I decided to order the 4130 mountain when it first came out. First impressions were solid. The Psylo fork and awesome geometry of the frame are top notch. The 4130 steel absorbs all of the abuse you can throw at it and feels much less rough on drops or tech trails when compared to an alum frame. I LOVE the gold patina, as it's more subdued in person than in the pictures. The wheels, wrapped with WTB Trail Boss tires are killer, tubeless setup was an absolute breeze and I'm happy to report no issues.
The bike gets 4/5 stars for a couple of reasons. First, the factory derailleur is a place holder for something better. Even with the clutch active I dropped the chain several times. The initial solution was an MRP chain guide. Second, the factory cassette. While the gearing range is perfect for where I ride, there are lots of techy climbs. The cassette did not survive, and cog #3 folded over in cog #4 during a climb. Finally, the derailleur took a bash that killed it. Swapped over to base level Deore 5100 for the cassette, shifter, and derailleur and all is great now.
My final gripe is that the crank set has to go if I want to add an aftermarket chainring. I have had the hankering for an AbsoluteBlack oval chainring, however the factory crankset is it's own pattern and will not fit any of their options. Luckily Deore is cheap and I'll be swapping that next!
Set this bike up as a trail bike with 27.5 tires and Fox 36, great quality frame with nice geometry. For the price point it is great. Would have given 5 stars but the internal cable routing for the dropper post is difficult, could be designed better. The metal guides for the internal routing fell into the frame and had to re-route the cable. Be careful when moving the housing too, it can get caught on the metal guides and split the housing.
This bike is a great time, and I'm super pleased with the build quality and geometry. I've been looking for a playful modern hardtail for a while. I have a full suspension trailbike and I miss the playful nature of a hardtail. I swapped all of my parts from that bike onto the 4130 Trail. The frame finish is good, and I had no surprises while building it up. The day after the build, I rode a bike park with some big berms, some gap jumps, pump track, etc. The bike was super fun and super predictable. It feels good, and there weren't any situations where it felt weird. I didn't really need to think about it at all, and that's a beautiful thing. I'm a big fan of what STATE does as a company, and I'm absolutely stoked to be riding this new entry into the MTB space. Oh...and it's a pretty bike. I've gotten loads of compliments on it. Keep it up, STATE.
So I don’t know what universe this color can be considered gold… Everybody who sees it says it’s military green. That aside this is one of the best riding bikes I’ve ever owned. I’ve got over three decades of MTB experience and I’ve written a lot of things, but this is the best feel by far. Smooth, steel ride, quality, excellent geometry, the fork was a complete surprise, and the shift and turned out to be rock solid it’s light. It’s nimble. And climbs like a mountain goat on steroids. I am 6 foot five 250 pounds so a sturdy ride with this epic handling at this price point is not easy to find. I highly recommend this bike… Maybe in the purple though ;-)
I am new to trail/mountain biking as I’ve been a long time road cyclist. This bike has been perfect for me as I am developing skills and enjoyment with this hard tail mountain bike. It very much meet my needs and it gives me something to really grow into in terms of a bike.
Fit and finish is perfect. Solid, well thought out bike!!
I've been wanting one of these for some time now. I am so stoked - I'd pictured it as an occasional bike for trail camping, fire roading, etc. Instead, I'm riding it several times per week. I've been riding DS enduro 29r bikes for years now, but never had a 29r hard tail MTB. This bike is so cool - proper trail-capable geo and a very sturdy stance. This pup doesn't flex like an XC minded frame. I got the Eagle Transmission upgrade only. Then upgraded to 4-pot brakes, dropper and SQ Lab carbon bar. Such a killer bike-- I've been riding it a ton. I'm 6'1", 185 lb and got the XL. Perfect ride fit and acceptable standover clearance. The bike actually came with 165mm cranks. But State graciously sent me a replacement in 175mm at no charge. Excellent customer service.
