4. Configuració i instal·lació
Proper installation is crucial for safety and performance. If you are not confident in your mechanical abilities, please seek professional assistance.
4.1 Eines necessàries
- Conjunt de claus hexagonals
- Clau dinamométrica
- Star nut setting tool (if steerer tube is uncut)
- Eina de configuració de la cursa de la corona
- Pipe cutter or hacksaw with guide (for steerer tube cutting)
- Brake caliper mounting bolts
- Greix
4.2 Passos d'instal·lació
- Prepare the Steerer Tube: If the steerer tube is too long for your frame, measure and cut it to the appropriate length, allowing for headset stack height and stem. Deburr the edges.
- Install Star Nut: Insert the star nut into the steerer tube using a star nut setting tool. Ensure it is straight and at the correct depth.
- Instal·la la cursa de la corona: Press the crown race onto the base of the steerer tube until it is fully seated against the fork crown. Use a crown race setting tool to avoid damage.
- Install Headset and Fork: Grease the headset bearings and cups. Insert the steerer tube through the head tube of your frame, then install the upper headset components, spacers, and stem.
- Tighten Stem: Align the stem with the front wheel and tighten the stem bolts to the manufacturer's recommended torque specifications.
- Instal·leu la roda davantera: Insert the 20mm thru axle through the fork dropouts and the front wheel hub. Securely tighten the thru axle.
- Install Brake Caliper: Mount your disc brake caliper to the fork's post mounts. Ensure proper alignment with the rotor and tighten the bolts to the brake manufacturer's specifications.
- Comprova la funcionalitat: Before riding, check that the steering is smooth, the brakes are functioning correctly, and the suspension moves freely without binding.
5. Instruccions de funcionament
The Zoom 680DH is an oil spring suspension fork designed to absorb impacts and provide a smoother ride. It features 170mm of travel, making it suitable for aggressive riding.
- Equitació: The fork will automatically compress and rebound to absorb bumps and maintain tire contact with the ground.
- Damping: As an oil spring fork, the damping characteristics are set by the internal oil and spring configuration. No external damping adjustments are typically available on this model.
- Precàrrega: Some oil spring forks may have a preload adjustment to fine-tune the spring stiffness. Refer to any markings on the fork crowns or top caps for potential adjustment points.
6. Manteniment
Regular maintenance will prolong the life of your fork and ensure safe operation.
- Neteja: After each ride, especially in dirty or wet conditions, clean the stanchions (the gold upper tubes) and seals with a soft cloth and mild soap and water. Avoid high-pressure washing directly at the seals.
- Lubricació: Apply a small amount of suspension-specific lubricant to the stanchions and cycle the fork a few times. Wipe off any excess.
- Inspecció: Periodically check for any leaks around the seals, scratches or damage on the stanchions, and ensure all bolts (crown, stem, brake caliper) are securely tightened to their specified torque.
- Servei: For internal service (oil changes, seal replacement), it is recommended to consult a professional bicycle mechanic or refer to a detailed service manual if available.
7. Solució De Problemes
Aquí teniu alguns problemes comuns i possibles solucions:
| Problema | Causa possible | Solució |

| Fork makes unusual noises (clunking, creaking) | Loose headset, stem, or crown bolts; worn bushings; lack of lubrication | Check and re-torque all bolts. Clean and lubricate stanchions. Inspect for wear. |
| Oil leaking from seals | Damaged or worn seals | Requires seal replacement. Consult a professional mechanic. |
| Fork not achieving full travel | Too much preload; internal issue | Reduce preload if adjustable. If problem persists, professional inspection is needed. |
8. Consells d'usuari
- For optimal performance, ensure your fork is always clean, especially the stanchions, to prevent dirt from entering the seals.
