3. Nastavení a instalace
3.1 Potřebné nástroje
- Hex key set (typically 4mm, 5mm)
- Řezačky kabelů
- Momentový klíč (doporučeno)
- Chain whip and cassette lockring tool (if replacing cassette)
- Chain tool (if adjusting chain length)
3.2 kroky instalace
- Remove Old Derailleur (if applicable): Shift to the smallest cog, loosen the cable anchor bolt, and remove the derailleur from the hanger using an appropriate hex key.
- Install New Derailleur: Thread the new microSHIFT Advent derailleur onto the derailleur hanger. Ensure it is properly seated and tighten the mounting bolt to the manufacturer's specified torque (refer to your bike's or derailleur's specific torque settings).
- Instalace řetězce: Route the chain through the derailleur cage. Ensure the chain is correctly routed over the guide pulley and tension pulley.
- Attach Shift Cable: Route the shift cable from the shifter to the derailleur. Pull the cable taut and secure it to the derailleur's cable anchor bolt. Do not overtighten initially.
- Adjust Limit Screws:
- High Limit (H) Screw: Adjust the H-screw so that the upper guide pulley aligns with the smallest cog when the chain is on the smallest cog. This prevents the chain from shifting off the cassette towards the frame.
- Low Limit (L) Screw: Shift the chain to the largest cog. Adjust the L-screw so that the upper guide pulley aligns with the largest cog. This prevents the chain from shifting into the spokes.
- Adjust B-Tension Screw: This screw adjusts the gap between the upper guide pulley and the cassette cogs. Adjust it to achieve optimal chain wrap and smooth shifting across all gears. There should be a small, consistent gap (typically 5-6mm) between the upper pulley and the cogs.
- Fine-Tune Shifting: With the chain on the smallest cog, turn the barrel adjuster on the shifter or derailleur clockwise until the chain begins to make noise or attempts to shift to a smaller cog. Then, turn it counter-clockwise one click at a time until shifting is smooth and quiet. Test all gears to ensure proper function.
4. Provoz
The microSHIFT Advent Super Short Rear Derailleur operates by moving the chain across the cassette cogs in response to input from the shifter. To shift gears, actuate your compatible 9-speed microSHIFT Advent shifter. The derailleur's precise mechanism and clutch system ensure quick, accurate, and reliable gear changes, even under load or on rough terrain. Always apply light pedal pressure when shifting to facilitate smooth transitions and prevent undue stress on the drivetrain components.
5. Údržba
Regular maintenance is crucial for optimal performance and longevity of your derailleur.
- Čištění: Periodically clean the derailleur, especially the pulleys and cage, to remove dirt, grime, and old lubricant. Use a degreaser and a brush, then rinse thoroughly.
- Mazání: After cleaning, apply a suitable bicycle chain lubricant to the chain and a small amount to the pivot points of the derailleur. Wipe off any excess lubricant.
- Inspekce: Regularly inspect the derailleur for any signs of damage, wear, or looseness in the mounting bolt or pivot points. Check the shift cable for fraying or corrosion.
- Seřízení spojky: The ratchet-and-pawl clutch is designed to be easily adjustable and repairable. If chain retention decreases, consult a professional bike mechanic for clutch inspection and adjustment.
6. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Poor or slow shifting | Incorrect cable tension, bent derailleur hanger, worn cable/housing, dirty drivetrain. | Adjust barrel adjuster, check derailleur hanger alignment, replace cable/housing, clean and lubricate drivetrain. |
| Chain skipping or jumping gears | Incorrect limit screw adjustment, worn chain/cassette, B-tension incorrect. | Re-adjust limit screws, check B-tension, inspect chain and cassette for wear and replace if necessary. |
| Excessive chain slap | Clutch not engaged or needs adjustment, chain too long. | Ensure clutch is engaged (if applicable), consult a mechanic for clutch adjustment, verify correct chain length. |
If issues persist after attempting these solutions, it is recommended to consult a professional bicycle mechanic.
