What kind of maintenance does the suspension fork require?

The suspension fork should be cleaned regularly. Annual servicing by a qualified bike mechanic is recommended to maintain performance and longevity.

Troubleshooting

Difficulty shifting gears.

Check the derailleur alignment and cable tension. Lubricate the chain and derailleurs. If the issue persists, consult a professional bike mechanic.

Brakes feel spongy or weak.

Inspect the brake pads for wear. Bleed the brakes to remove air from the hydraulic system. If the problem continues, have a professional check for leaks.
