—— Professional Grade Cycling Hubs ——
Lightweight straight pull boost mountain bike hub engineered for steel spokes, built with reliable 36T PG ratchet and multi freehub compatibility for trail & enduro off-road riding.
01 / Front Hub Engineering
The M330 Front Hub merges aerospace-grade materials with precision machining to deliver unmatched performance and reliability.
Boasting a 36.6–40.2mm front P.C.D range, this hub delivers balanced spoke tension to dampen trail vibrations and harsh impacts. Combining T6 6061 aluminum for the hub shell and high-strength 7075 aluminum for high-load components including the freehub and axle, it strikes a perfect balance between rugged durability and lightweight performance.
02 / Rear Hub Performance
A quad four-bearing rear design with interchangeable freehub bodies delivers increased structural support, smooth operation, and long-term reliability.
Rear dual-stage P.C.D Φ40.0–Φ40.5mm optimizes spoke bracing angle to boost wheel rigidity under hard braking loads.
Impact-resistant CNC machined alloys built for harsh off-road mountain conditions
Tempered AL6061 alloy forms the main shell, balancing light weight and vibration absorption for cross-country and trail bikes.
AL7075 aerospace alloy used on axles and freehubs to resist torque fatigue from jumps and aggressive pedaling.
