Tough as nails and ready for anything, the State Bicycle Co. 4130 Trail Mountain Bike is a no-BS trail machine designed to crush climbs, rip descents, and handle whatever you throw at it. Whether you're slashing singletrack, hammering urban shortcuts, or packing up for an epic bikepacking trip, this bike is built to send it.

Quick Features:

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.
12-Speed Shimano Deore Drivetrain: A tough-as-hell 1x12 setup with Shimano Deore M6100 shifter and rear derailleur, paired with an 11–50T cassette for big climbing range and clean, reliable shifting.
Universal Derailleur Hanger (UDH) Compatibility: Future-proofed for modern drivetrain tech and easier maintenance, because you don’t need to be stressing parts availability.
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.
Internal Dropper Routing: With a 31.6mm seat tube and internal cable routing, upgrading to a dropper post is hassle-free.
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.
RockShox Psylo Silver RC – 130mm Travel, 35mm Stanchions: At $1,499.99, you’d normally see a budget fork with spindly stanchions and questionable performance. Not here. The RockShox Psylo Silver RC features 35mm steel upper tubes for enhanced steering precision and stiffness when blasting technical descents. The Motion Control damper and Solo Air spring keep things plush, while premium bushings reduce friction for a buttery-smooth ride over rough terrain.
