Rear Chain Guide Guard Block

The NiceCNC chain guide is designed to replace worn or damaged OEM components and support consistent chain alignment during riding. The guide uses a PA-66 (Nylon-66) slider to provide wear resistance and maintain guiding performance under regular use. The 3D-shaped slider design helps reduce the impact of debris from multiple directions, supporting smoother chain operation in varying conditions.

The housing is constructed from CNC-machined 6061 aluminum alloy, offering a balance of durability and reduced weight. The anodized finish improves corrosion resistance while maintaining a clean appearance. The design is intended to integrate with existing mounting points, with installation supported by either supplied or original hardware depending on the model.
