Upper Left Pawl

The upper left pawl works in conjunction with the right pawl to provide precise indexing and power transfer in modern mountain bike rear hubs. Engineered with asymmetrical tooth profiles and specialized surface treatments, this component delivers reliable engagement under high-torque conditions while maintaining smooth disengagement during coasting.

Product Parameter (Specification)

Product Feature And Application

High Design Freedom: Enables single-step formation of complex 3D geometries, overcoming limitations of traditional machining.
Excellent Material Properties: High part density (>97%) and mechanical properties close to forging, superior to casting.
High Precision & Surface Finish: Tight tolerances (±0.3-0.5%) and good surface quality minimize secondary processing.
Cost-Effective Mass Production: High efficiency and low per-part cost after mold creation, ideal for high-volume runs.
High Material Utilization: Near 100% yield, supports sustainable manufacturing.
Key Applications in Bicycles:
MIM is ideal for high-end cycling components demanding lightweight design, strength, complex functionality, and production consistency, such as drivetrain parts (chainrings, derailleur gears), braking system components (pistons, mechanisms), connectivity parts (headset components, clamps), pedal retention mechanisms, and internal shifting components.
