Maintenance Tips

• Clean frame and fork after trail, mud, or wet rides to prevent corrosion and preserve finish.
• 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, snowy, or coastal conditions.
• Grease all threaded interfaces (bottom bracket, headset, thru-axles, bottle/rack mounts) to prevent seizing over time.
• Check suspension-corrected fork, dropouts, and disc brake mounts frequently for tightness and alignment after aggressive trail riding.
• Maintain drivetrain (chain, cassette, chainrings) with regular cleaning and lubrication, especially after muddy rides.
• Ensure tire clearance stays clear of packed mud or debris, particularly with high-volume 29+ tires.
• Inspect wheel, hub, and axle components regularly due to trail impacts and wide tire loads.
• Avoid pressure washing to protect bearings, seals, and frame joints from water intrusion.
• Store indoors in a dry place to maximize frame durability and finish longevity.
