Buying Guide
Key considerations when choosing a chainring guard:
- Compatibility: Confirm crankset pattern (BCD), number of mounting holes, and chainring size range (e.g., 32–42T).
- Material: Plastic guards are lightweight and affordable; aluminum offers higher impact resistance and durability; PC plastic offers rigidity with good protection.
- Protection scope: Decide if you need grease protection for pants, droplet shielding, or lightweight bike-borne protection against small impacts.
- Weight and clearance: For aggressive riding, prefer guards with minimal weight and a profile that won’t rub on pedals or cranks.
- Installation complexity: Some guards require standard bolts; others may need custom spacing. Measure hole spacing carefully.
