The 4130 Trail Frame & Fork Set is the perfect foundation for your next hardtail shredder. Made from double-butted 4130 Chromoly steel, this frame is built to take a beating while delivering a smooth, lively ride feel. With progressive trail geometry, UDH compatibility, and clearance for big rubber, it’s ready for anything from techy singletrack to loaded bikepacking missions.

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.
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: 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.
