Introducció
This manual provides essential information for the proper installation, operation, and maintenance of your Shimano Tourney TY300 6/7-Speed Rear Derailleur. Adhering to these instructions will ensure optimal performance, safety, and longevity of your component. The TY300 series is designed for reliable shifting across 6 or 7-speed drivetrains, featuring Shimano's SIS (Shimano Index System) for precise gear changes.
Informació de seguretat

- Regularly inspect your derailleur for damage or wear. Do not use if components are bent or broken.
Configuració i instal·lació
Proper installation is crucial for the performance of your rear derailleur. The TY300 model typically comes with a dropout claw hanger for easy mounting on frames without an integrated derailleur hanger.
- Mounting the Derailleur: Attach the derailleur to the bicycle frame's dropout using the integrated claw hanger. Ensure it is securely tightened to the manufacturer's specifications.
- Instal·lació de cables: Route the shift cable from the shifter lever through the frame guides to the derailleur. Secure the cable to the derailleur's cable fixing bolt, ensuring proper tension.
- Low Limit Screw Adjustment (L-screw): Adjust the 'L' limit screw so that the upper guide pulley is directly aligned with the smallest cog when the chain is on the smallest cog. This prevents the chain from shifting into the spokes.
- High Limit Screw Adjustment (H-screw): Adjust the 'H' limit screw so that the upper guide pulley is directly aligned with the largest cog when the chain is on the largest cog. This prevents the chain from shifting off the largest cog and into the frame.
- B-Tension Adjustment: With the chain on the largest cog and the largest chainring, adjust the B-tension screw to ensure adequate clearance (5-6mm) between the upper guide pulley and the largest cog. This optimizes shifting performance.
- Indexing Adjustment: Fine-tune the cable tension using the barrel adjuster on the shifter or derailleur until shifts are smooth and precise across all gears.
Funcionament
The Shimano Tourney TY300 rear derailleur utilizes the SIS (Shimano Index System) for reliable and consistent gear changes. Shifting is performed by actuating your bicycle's shift levers.
- SIS Shifting: The indexed system ensures that each click of the shifter corresponds to a precise movement of the derailleur, moving the chain to the next cog.
- Double Servo Mechanism: This feature allows the guide pulley to track the cogs closely as it moves front to back, optimizing each shift for smoothness and accuracy.
- MegaRange Compatibility (TX models): Some TY300 models (TX) come with a Smart Cage, providing compatibility with MegaRange freewheels/cassettes for a wider gear range.
Manteniment
Regular maintenance extends the life and performance of your derailleur.
- Neteja: Keep the derailleur, especially the pulleys and cage, free from dirt and grime. Use a degreaser and brush, then rinse and dry thoroughly.
- Lubricació: Apply a light lubricant to the pivot points of the derailleur and the chain regularly. Avoid over-lubricating the pulleys.
- Inspecció del cable: Check the shift cable for fraying or corrosion. Replace if necessary to maintain smooth shifting.
- Limit Screw Check: Periodically verify that the limit screws are still correctly set to prevent over-shifting.
- B-Tension Check: Ensure the B-tension gap remains optimal for your drivetrain.
Resolució de problemes
Problemes comuns i les seves possibles solucions:
| Problema | Causa possible | Solució |
|---|---|---|
| Difficulty shifting to smaller cogs | Cable tension too high, H-screw too tight | Loosen barrel adjuster (turn clockwise), check H-screw adjustment. |
| Difficulty shifting to larger cogs | Cable tension too low, L-screw too tight | Tighten barrel adjuster (turn counter-clockwise), check L-screw adjustment. |
| Chain rubbing or noisy shifting | Incorrect indexing, bent derailleur hanger, worn chain/cogs | Adjust indexing, inspect hanger for alignment, check drivetrain wear. |
| Derailleur hitting spokes | L-screw incorrectly set, bent derailleur hanger | Re-adjust L-screw, check and straighten derailleur hanger. |
