Buying Guide
- Mounting standard: All listed guards fit ISCG05 mounts. Confirm your frame has ISCG05 bosses before purchasing.
- Chainring compatibility: Most guards support 26T–36T single chainrings; some offer wider ranges (e.g., 22T–40T). Choose based on your typical gearing.
- Material and weight: Aluminum alloys (6061, 7075-T6) provide a balance of strength and lightness. Heavier guards offer more impact resistance but may affect handling slightly.
