While the cycling industry has spent years convincing riders they need complex linkages and fragile hardware just to hit the trails, Arizona’s State Bicycle Co. has continually delivered the opposite: honest, tough rigs built for riders who care more about sending it than nursing delicate parts. Their latest release is the State Bicycle Co. 4130 Trail Mountain Bike in Sagebrush Green.
Priced at an extraordinary $1,999.99 (~£1,550), this steel shredder pairs progressive trail geometry and a RockShox fork with cutting-edge SRAM Eagle Transmission wireless shifting in a build that BIKE Magazine noted “has no business being under $2,000”.
Hangerless Wireless Shifting: The SRAM Eagle Transmission
The standout innovation here is the integration of SRAM’s revolutionary Eagle Transmission (T-Type). For decades, derailleurs have hung from a sacrificial, easily bent tab of aluminium.
If your bike tipped over, caught a rock, or shifted in the back of a van, that hanger would bend, instantly compromising your indexing for the entire ride.
State has eradicated that headache completely. Utilising the Universal Derailleur Hanger (UDH) standard, the S1000 T-Type derailleur bolts directly through the frame and clamps around the rear axle.
There is no derailleur hanger to bend, no B-gap to guess, and zero limit screws to adjust. Setup is a simple, one-time procedure, and because the derailleur firmware tracks the exact physical geometry of the cogs, you can execute crisp wireless gear changes under full pedal power—standing up, stomping through rock gardens, or grinding mid-climb.
Massive 520% Range & HG Freehub Simplicity
Out back, the bike runs an XS-1270 cassette offering a 10–52t spread—delivering a colossal 520% gear range. Whether you are spinning up loose climbs or hammering down flat transfer trails, you will never find yourself searching for an extra gear.
Better still, SRAM engineered this cassette to mount to a standard splined HG freehub body rather than requiring an expensive proprietary XD driver. That means no need to swap out rear wheels or rebuild hubs down the line.
To make long-term ownership even more sensible, gears 8 through 12 come off as a separate replaceable cluster, meaning you can swap out worn climbing cogs without having to buy a whole new cassette.
Progressive Steel Geometry & Trail-Ready Hardware
Holding everything together is a double-butted 4130 chromoly steel frame in an understated Sagebrush Green.
Steel delivers a natural compliance that dampens harsh trail chatter far better than aluminium without the brittle nature of carbon.
With a slack 65-degree head tube angle, a low-slung top tube, and a roomy front-centre, the bike remains planted on steep, rooty descents while maintaining agile handling in tight berms.
Up front, a RockShox Psylo Silver RC fork provides 130mm of controlled travel supported by stout 35mm stanchions and a Motion Control damper.
The cockpit is streamlined with an AXS Pod wireless controller on the bars, while the frame features internal routing for a 31.6mm dropper post, a creak-free 73mm BSA threaded bottom bracket, and triple bottle cage mounts on the downtube.
