PERFORMANCE ARCHITECTURE

One hub platform, configured for different wheel builds.

A flexible hub architecture designed to simplify product selection while preserving application-specific performance. Key interfaces—including engagement, bearing structure, axle configuration, and freehub compatibility—can be specified to match the intended wheel build and drivetrain system.

High-Response Ratchet Engagement

6-Pawl 2-Tooth 180T System for Faster Power Transfer

The upgraded 6-pawl 2-tooth engagement system with larger pawls provides faster response and improved torque transmission. The optimized structure distributes loads more evenly, enhancing engagement stability, durability, and control under demanding MTB conditions.

4-in-1 Adaptable Hub Platform

Flexible Axle Compatibility for Multiple MTB Applications

ARC's 4-in-1 hub design supports multiple axle standards with precision-engineered aluminum components. The optimized construction improves compatibility, maintains structural reliability, and provides a versatile solution for different MTB wheel builds.
