Maintenance Tips
- Clean frame and fork after trail, gravel, or wet rides to prevent corrosion and grime 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, snowy, or coastal conditions.
- Grease all threaded interfaces (bottom bracket, headset, thru-axles, bottle/rack mounts) to prevent seizing over time.
- Check rack, cargo cage, and frame mounts frequently—Ogre is often used for loaded touring and commuting.
- Verify disc brake mounts and dropout alignment regularly for reliable braking and wheel fit.
- Maintain drivetrain (chain, cassette, chainrings) with consistent cleaning and lubrication, especially after muddy rides.
- Ensure tire clearance stays clear of packed mud or debris on rough or multi-day routes.
- Avoid pressure washing to protect bearings, seals, and frame joints from water intrusion.
- Store indoors in a dry environment to maximize steel frame longevity and finish durability.
