Maintenance Tips

• Clean frame and fork after gravel, mud, or wet rides to prevent corrosion and buildup.
• Inspect chromoly steel frame regularly for paint chips, rust spots, dents, or stress marks; touch up exposed steel promptly.
• Apply internal frame rust inhibitor annually, especially in wet, humid, or coastal environments.
• Grease all threaded interfaces (bottom bracket, headset, thru-axles, bottle/rack mounts) to prevent seizing.
• Check disc brake mounts and dropout alignment regularly for consistent braking and wheel fit.
• Maintain drivetrain (chain, cassette, chainring) with frequent cleaning and lubrication, especially after rough terrain riding.
• Ensure tire clearance stays free of packed mud or debris, particularly with wider 27.5 gravel setups.
• Inspect rack and frame mounts regularly if used for bikepacking or cargo setups.
• Avoid pressure washing to protect bearings and prevent water intrusion into frame tubes.
• Store indoors in a dry place to preserve steel durability and finish longevity.
