Maintenance Tips
- Clean the frame after mud, snow, sand, or wet rides to prevent corrosion and preserve the steel finish.
- Inspect the chromoly frame and fork regularly for paint chips, rust spots, dents, or impact damage.
- Touch up exposed metal quickly and apply internal frame rust protection annually for long-term durability.
- Grease all threaded contact points (bottom bracket, headset, thru-axles, accessory mounts) to prevent seizing.
- Check rack, bottle, and cargo mounts frequently—fat bike use often involves heavier loads and rough terrain.
- Keep dropouts and disc brake mounts clean for safe, consistent braking performance in harsh conditions.
- Maintain tire clearance by clearing packed mud, snow, or debris during and after rides.
- Avoid high-pressure washing, which can force water into bearings and frame tubes.
- Store indoors in a dry space, especially after winter or wet-weather riding.
