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.

Standard 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

Rigid — Carbon 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

$1,899.99
$100 less than suspension · 4 lb 6 oz lighter

Rigid — Steel 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

No Fork Frame-Up — Bring Your Own

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

$1,599.99
$400 less than suspension

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.
• Double-Butted 4130 Chromoly Steel Frame: Tougher than aluminum and smoother than carbon, our double-butted 4130 Chromoly frame absorbs trail chatter and takes a beating without flinching.
• Four Fork Options: RockShox Psylo Silver RC 130mm suspension, rigid carbon, rigid steel, or no fork at all. One frame, four very different bikes — see Choose Your Fork above.
• UDH Frame: Not just compatible — required, and put to work. The hangerless derailleur mounts through it.
• Internal Dropper Routing: 31.6mm seat tube with internal routing — or skip the routing entirely and go wireless. Both options below.
• Threaded Bottom Bracket (73mm BSA): Reliable, creak-free, and easy to service.
• More Mounting Points: Triple bottle cage mounts on the downtube — because adventure doesn't come with limits.

Pair the Seekrun with Transmission and there isn't a single shift or dropper cable on the bike. Nothing to route, nothing to trim, nothing to replace.

Choose Your Brakes

Choose Your Handlebar

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.

Standard Equipment

• Frame: Double-butted 4130 Chromoly steel, UDH, 73mm BSA threaded BB, internal dropper routing
• Fork: Your choice — see Choose Your Fork above
• Rear Derailleur: SRAM S1000 Eagle Transmission AXS, 12-speed, max 52T, hangerless Full Mount
• Cassette: SRAM XS-1270 Eagle Transmission, 10–52T, HG driver
• Chain: SRAM Eagle T-Type
• Controller: SRAM AXS Pod
• Battery & Charger: Included
• Crankset: SBC 32T narrow-wide, 165mm, direct mount
• Saddle: Trail-ready PU pad with steel rails
• Stem: SBC 3D-forged alloy, 35mm clamp
• Pedals: Not included

Max Tire Clearance

• Frame: 29" up to 2.6" / 27.5" up to 3.0"
• Suspension fork: 29" up to 2.6"
• Rigid steel fork: 29" up to 3.0"
• Rigid carbon fork: 29" up to 3.0"

The rigid forks clear more rubber than the frame does — on a matched pair of tires the frame's 2.6" rear is the limit for the whole bike.

⚠️ Assembly Required: This bike ships partially unassembled and will require crank installation, wheel installation, and fork setup (the steerer tube comes uncut). The Transmission derailleur mounts through the rear axle and follows SRAM's setup procedure — there are no limit screws or indexing to adjust, but the sequence needs to be followed exactly. We strongly recommend professional assembly to ensure the safest and highest quality ride experience.
