5. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

This derailleur is compatible with Tiagra 4700 10-speed road shifters and GRX R400 shifters. Ensure your drivetrain components are compatible before installation.

5.1 Mounting the Derailleur

1. Ensure the derailleur hanger on your frame is straight and undamaged.
2. Apply a small amount of grease to the derailleur hanger bolt threads.
3. Thread the derailleur onto the hanger. Tighten the mounting bolt to the manufacturer's specified torque (typically 8-10 Nm).

5.2 Cable Installation and Routing

1. Route the shift cable from your shifter through the frame and into the derailleur's cable stop.
2. Ensure the cable housing is cut to the correct length and that the ends are properly prepared with ferrules.
3. With the shifter in the highest gear (smallest cog position), pull the cable taut and secure it to the derailleur's cable fixing bolt. Tighten the bolt to the specified torque.

5.3 Limit Screw Adjustment

Adjust the High (H) and Low (L) limit screws to prevent the chain from shifting beyond the smallest and largest cogs, respectively.

• High Limit (H): With the chain on the smallest cog, turn the H-screw until the guide pulley aligns directly under the smallest cog.
• Low Limit (L): With the chain on the largest cog, turn the L-screw until the guide pulley aligns directly under the largest cog.

5.4 B-Tension Adjustment

Adjust the B-tension screw to set the gap between the guide pulley and the largest cog. This gap should be approximately 5-6mm for optimal shifting performance.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The microSHIFT Centos Rear Derailleur provides smooth and accurate 10-speed gear changes. To operate, use your compatible shifter to move the chain between different cogs on your cassette.

• Shifting Up (to smaller cogs): Press the appropriate lever on your shifter to move the chain to a smaller, higher-speed cog.
• Shifting Down (to larger cogs): Press the appropriate lever on your shifter to move the chain to a larger, lower-speed cog.
• Smooth Shifting: Always pedal forward with moderate pressure when shifting. Avoid shifting under heavy load or while standing on the pedals.

7. പരിപാലനം

Regular maintenance will prolong the life and performance of your derailleur.

• വൃത്തിയാക്കൽ: Regularly clean the derailleur, especially the pulleys, with a degreaser and brush. Rinse thoroughly and dry.
• ലൂബ്രിക്കേഷൻ: Apply a small amount of bicycle-specific lubricant to the pivot points of the derailleur and the pulley bearings after cleaning or if they appear dry. Avoid over-lubrication.
• Cable and Housing: Inspect shift cables and housing for fraying, kinks, or corrosion. Replace them annually or as needed to maintain crisp shifting.
• പുള്ളി പരിശോധന: Check the guide and tension pulleys for wear. Worn pulleys can lead to poor shifting and chain noise. Replace if teeth are visibly worn or damaged.

8. പ്രശ്‌നപരിഹാരം

If you experience issues with your derailleur, refer to the following common problems and solutions:

• മോശം ഷിഫ്റ്റിംഗ് പ്രകടനം:
  • Check cable tension using the barrel adjuster on the derailleur or shifter.
  • Verify limit screw adjustments (H and L).
  • Inspect cable and housing for friction or damage.
  • ഡെറില്ലർ ഹാംഗർ വളഞ്ഞിട്ടില്ലെന്ന് ഉറപ്പാക്കുക.
• Chain Rubbing or Noise:
  • Adjust B-tension screw to ensure proper clearance between the guide pulley and the largest cog.
  • Check for worn chain or cassette cogs.
• Derailleur Not Moving:
  • Ensure the shift cable is properly attached and not broken.
  • Check for obstructions or damage to the derailleur body.

For persistent issues, consult a professional bicycle mechanic.
