Compatibility

Construction & Materials

To achieve an optimal balance of strength, durability, and weight savings, the hanger features a hybrid construction:

• Carbon fiber reinforcement around the fastening section for improved fatigue resistance and reduced weight

• AL7075-T6 aerospace-grade aluminum alloy main body

• Full CNC-machined construction for precise fit and alignment

• Hard anodized surface finish for enhanced wear and corrosion resistance

Thread Pitch Options

Different frame manufacturers use different rear thru-axle thread pitches. Please verify your original thru-axle specification before placing an order.

Remove the original rear thru-axle and check the laser markings on the axle shaft or threaded section.

• Choose M12×1.5 if your axle is marked:
  M12(P1.5)

• Choose M12×1.0 if your axle is marked:
  M12(P1.0)

Reverse-Thread Lockring Design

To prevent loosening caused by vibration during riding, the supplied lockring nut utilizes a reverse-thread (left-hand thread) design.

Thread Direction

• Tighten: Counterclockwise

• Loosen: Clockwise

This design helps maintain a secure connection and improves long-term reliability under demanding riding conditions.
