4. 설정 및 설치

Follow these steps for proper installation of your Revoshift SL-RV400-7R shifter. Professional installation is recommended.

1. 핸들바 장착: Slide the shifter onto the right side of your handlebar. Position it comfortably for easy access and operation. Secure the shifter clamp bolt to the recommended torque specification (refer to your bicycle's or handlebar's manual for specific torque values).
2. 케이블 설치:
   • Ensure the shifter is in the highest gear position (smallest number on the optical display, if applicable).
   • Insert the shifter cable (inner wire) into the designated port on the shifter body.
   • Route the cable through the cable housing (sold separately) and along your bicycle frame, securing it with cable ties or frame guides.
   • Connect the cable to your rear derailleur, ensuring proper tension.
3. 변속기 조정: Adjust your rear derailleur's limit screws and B-tension screw according to the derailleur manufacturer's instructions. This ensures the chain does not overshift or undershift.
4. 인덱싱 조정: With the chain on the smallest cog, turn the barrel adjuster on the shifter or derailleur until the chain shifts smoothly through all 7 gears. Fine-tune as necessary to eliminate any hesitation or skipping.
5. 최종 확인: Test all gear shifts while the bicycle is stationary and then during a short ride. Ensure smooth operation and that the optical gear display accurately reflects the current gear.

5. 사용 설명서

The Revoshift SL-RV400-7R is a twist-grip shifter designed for intuitive gear changes.

• Shifting Up (Harder Gear): To shift to a higher gear (smaller cog on the rear wheel, for faster pedaling), twist the grip forward (towards the front of the bike).
• Shifting Down (Easier Gear): To shift to a lower gear (larger cog on the rear wheel, for easier pedaling), twist the grip backward (towards the rider).
• 광학 기어 표시: The integrated optical gear display provides a clear visual indication of your current gear position, allowing you to quickly identify which gear you are in without looking down at the cassette.
• 부드러운 변속: For optimal performance and to prevent damage to your drivetrain, ease off the pedal pressure slightly while shifting gears. Avoid shifting under heavy load.

6. 유지관리

Regular maintenance ensures the longevity and reliable performance of your shifter.

• 청소: Periodically clean the shifter body and grip with a damp cloth. Avoid using harsh chemicals or solvents that could damage the plastic components or rubber grip.
• 케이블 검사: Inspect the shifter cable and housing regularly for fraying, kinks, or corrosion. Replace the cable and housing if any damage is observed. A worn cable can lead to poor shifting performance.
• 매끄럽게 하기: Apply a small amount of bicycle-specific lubricant to the inner shifter cable where it enters the housing and at the derailleur connection points. Do not over-lubricate the shifter mechanism itself unless specified by SHIMANO.
• 견고성 확인: Periodically check that the shifter clamp bolt is securely tightened to the handlebar.

7. 문제 해결

If you experience issues with your Revoshift SL-RV400-7R, consider the following common problems and solutions:

• 기어 변속이 원활하지 않음:
  • Check cable tension. Adjust the barrel adjuster on the shifter or derailleur to increase or decrease tension.
  • Inspect the shifter cable and housing for damage or excessive friction. Replace if necessary.
  • Ensure the derailleur is properly aligned and its limit screws are correctly set.
• Shifter Feels Stiff or Hard to Twist:
  • The cable or housing may be corroded or dirty. Replace the cable and housing.
  • Ensure the shifter is not overtightened on the handlebar, which can impede its twisting motion.
• Optical Gear Display Not Showing Correct Gear:
  • This usually indicates an issue with cable tension or derailleur adjustment. Re-index the gears.

For persistent issues, consult a professional bicycle mechanic.
