microSHIFT Advent 9-Speed Rear Derailleur (RD-M619M) Instruction Manual

1. 제품 오버view

The microSHIFT Advent 9-Speed Rear Derailleur (Model RD-M619M) is designed for reliable and consistent shifting performance on bicycles equipped with a 9-speed drivetrain. It features a medium cage design and is compatible with microSHIFT ADVENT shifters and cassettes, supporting a largest cog of up to 46 teeth. This derailleur is constructed from durable alloy steel and aluminum, ensuring longevity and robust operation.

3. 설정 및 설치

올바른 설치는 최적의 성능과 안전에 매우 중요합니다. 설치 과정 중 확실하지 않은 부분이 있으면 전문 자전거 정비사에게 문의하십시오.

3.1 필요한 도구

• Hex wrenches (typically 5mm)
• 케이블 절단기
• 케이블 크림프
• 토크렌치(추천)
• Chain whip and cassette tool (if replacing cassette)

3.2 변속기 장착

1. Ensure your derailleur hanger is straight and undamaged.
2. Apply a small amount of grease to the derailleur hanger threads.
3. Thread the derailleur onto the hanger by hand, ensuring it is properly aligned.
4. Tighten the derailleur mounting bolt to the manufacturer's specified torque (refer to your bicycle or derailleur hanger manual for specific torque values, typically around 8-10 Nm).

3.3 Chain Installation and Sizing

1. Route the chain through the derailleur cage, ensuring it passes correctly over the guide and tension pulleys.
2. Determine the correct chain length. A common method is to wrap the chain around the largest chainring and largest cog, bypassing the derailleur. Add two full links (one inner and one outer) to this length.
3. Connect the chain using a master link or chain pin according to the chain manufacturer's instructions.

3.4 Cable Routing and Adjustment

1. Route the shifter cable from the shifter to the derailleur, ensuring it runs smoothly through all cable housing and guides.
2. Secure the cable to the derailleur's cable anchor bolt. Do not overtighten initially.
3. 조정하다 High (H) limit screw: With the chain on the smallest cog, turn the H-screw until the guide pulley is directly aligned with the smallest cog. The chain should not rub against the frame or jump off the cog.
4. 조정하다 Low (L) limit screw: Shift the chain to the largest cog. Turn the L-screw until the guide pulley is directly aligned with the largest cog. The chain should not rub against the spokes or jump off the cog.
5. 조정하다 B-텐션 나사: With the chain on the largest cog, adjust the B-tension screw to set the gap between the upper guide pulley and the largest cog. A gap of 5-6mm is generally recommended for optimal shifting.
6. Fine-tune shifting: Use the barrel adjuster on the shifter or derailleur to achieve crisp shifts. Turn clockwise to move the derailleur inward (towards larger cogs) and counter-clockwise to move it outward (towards smaller cogs).

4. 사용 설명서

The microSHIFT Advent 9-Speed Rear Derailleur operates in conjunction with a compatible microSHIFT Advent 9-speed shifter.

• Upshifting (to smaller cogs): Use the smaller lever on your shifter to move the chain to smaller, harder-to-pedal cogs. This is typically used for increasing speed or descending.
• Downshifting (to larger cogs): Use the larger lever on your shifter to move the chain to larger, easier-to-pedal cogs. This is typically used for climbing or reducing effort.
• Always shift gears while pedaling forward with moderate pressure. Avoid shifting under heavy load or while stationary to prevent damage to the drivetrain components.

5. 유지관리

Regular maintenance extends the life and performance of your derailleur.

• 청소: Regularly clean the derailleur, especially the pulleys, to remove dirt, grime, and old lubricant. Use a degreaser and a brush, then rinse thoroughly.
• 매끄럽게 하기: After cleaning, apply a light bicycle-specific lubricant to the pivot points of the derailleur and the chain. Wipe off any excess lubricant.
• 점검: Periodically check the derailleur for any signs of damage, bent components, or loose bolts. Ensure the derailleur hanger is straight.
• 케이블 및 하우징: Inspect shifter cables and housing for fraying, kinks, or corrosion. Replace them if necessary to maintain smooth shifting.
• Pulley Wheels: Check the pulley wheels for wear. Worn pulleys can lead to poor shifting and increased noise. Replace them if the teeth are significantly worn or damaged.

6. 문제 해결

일반적인 문제와 잠재적 해결책.

6.1 변속 성능 불량

• 징후: Slow or hesitant shifts, chain not moving to desired cog.
  • 해결책: Check cable tension. Adjust the barrel adjuster (turn counter-clockwise for slower shifts, clockwise for faster shifts).
  • 해결책: Inspect cable and housing for friction or damage. Replace if necessary.
  • 해결책: Verify limit screw settings (H and L).
  • 해결책: Check for a bent derailleur hanger. A bent hanger is a common cause of poor shifting and requires straightening or replacement.
  • 해결책: 체인이 깨끗하고 윤활 처리되어 있는지 확인하십시오.

6.2 Derailleur Noise

• 징후: Clicking, grinding, or rubbing sounds.
  • 해결책: Check limit screws (H and L) to ensure the derailleur is not over-shifting or under-shifting.
  • 해결책: Adjust B-tension screw to ensure proper clearance between the guide pulley and the largest cog.
  • 해결책: Clean and lubricate the derailleur and chain.
  • 해결책: Inspect pulley wheels for wear or damage.
  • 해결책: 변속기 행어가 휘어졌는지 확인하십시오.

6.3 Chain Dropping

• 징후: Chain falls off the smallest or largest cog.
  • 해결책: Re-adjust H (high) and L (low) limit screws carefully.
  • 해결책: 변속기 행어가 휘어졌는지 확인하십시오.
