With clearance for wide tires, a 150mm fork travel spec, and a 65.0° head angle, this is a frame built for loose, chunky singletrack where you want tire volume and trail geometry, not race efficiency.\u003c\/p\u003e\n\u003cp\u003eThe Gen 4 adds UDH (Universal Derailleur Hanger) for AXS and Shimano Linkglide compatibility, internal routing for both derailleur and dropper post, integrated frame storage, and a bolt-on downtube guard. The threaded bottom bracket is a welcome detail — no press-fit complications on a hardtail that may see more abuse than a dedicated XC race sled. ISCG 05 mount allows a chain guide for rowdier terrain. The 148x12mm thru axle and tapered headtube (ZS\/IS) are current standards that simplify the build.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eRiders who want a trail-geometry hardtail with wide tire clearance and a modern component spec\u003c\/li\u003e\n\u003cli\u003eBudget-conscious builders who want a hardtail that can handle real trail riding, not just gravel or XC tracks\u003c\/li\u003e\n\u003cli\u003eRiders who plan to run a 1x drivetrain with dropper post — internal routing for both is built in\u003c\/li\u003e\n\u003cli\u003eNot ideal for: XC race builds or riders who need full suspension for technical terrain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eWhat to Look For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFork:\u003c\/strong\u003e Spec'd for a 150mm travel fork — run a quality trail fork, not an XC fork\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUDH:\u003c\/strong\u003e Built-in UDH supports SRAM AXS and Shimano Linkglide rear derailleurs directly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded BB:\u003c\/strong\u003e BSA threaded shell — a durable, serviceable standard that simplifies crankset selection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated storage:\u003c\/strong\u003e Frame bag\/storage built in — works best with compatible packs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eFrame — Alpha Platinum Aluminum, Hardtail:\u003c\/strong\u003e Slack trail geometry (65.0° head angle) built for 150mm fork travel, ISCG 05 chain guide mount, threaded BB, UDH, bolt-on downtube guard, and integrated storage.
