The microSHIFT Estes RD-M220L Rear Derailleur consists of several key parts:

• Derailleur Body: The main structure housing the pivot points and springs.
• 새장: The long cage assembly that guides the chain, including the upper and lower jockey wheels.
• B-Tension Screw: Adjusts the distance between the upper jockey wheel and the largest cassette cog.
• High (H) Limit Screw: Prevents the derailleur from shifting the chain beyond the smallest cog.
• Low (L) Limit Screw: Prevents the derailleur from shifting the chain beyond the largest cog.
• Cable Anchor Bolt: Secures the shift cable to the derailleur.

4. 설치 및 설정

4.1 필요한 도구

• Hex wrenches (typically 5mm)
• 케이블 절단기
• 토크렌치(추천)
• 자전거 그리스

4.2 Derailleur Mounting

1. Apply a small amount of grease to the derailleur hanger threads on your bicycle frame.
2. Thread the derailleur mounting bolt into the hanger. Ensure the B-knuckle tab is correctly positioned against the hanger stop.
3. Tighten the mounting bolt to the manufacturer's specified torque (typically 8-10 Nm).

4.3 체인 설치

1. Route the chain through the front derailleur (if applicable), over the smallest chainring, and then through the rear derailleur cage. Ensure the chain passes correctly over the upper and lower jockey wheels.
2. Connect the chain using a master link or chain pin according to the chain manufacturer's instructions.

4.4 Cable Routing and Attachment

1. Route the shift cable from your shifter through the frame's cable guides and into the derailleur's cable housing stop.
2. Pull the cable taut and secure it under the cable anchor bolt. Do not overtighten initially.

4.5 Limit Screw Adjustment (H and L)

Limit screws prevent the chain from shifting off the smallest or largest cog.

1. High (H) Limit: Shift the chain to the smallest cog on the cassette. Adjust the H-screw so that the upper jockey wheel is directly aligned with the smallest cog. The chain should run smoothly without rubbing.
2. Low (L) Limit: Shift the chain to the largest cog on the cassette. Adjust the L-screw so that the upper jockey wheel is directly aligned with the largest cog. The chain should run smoothly without rubbing.

4.6 B-Tension Adjustment

The B-tension screw adjusts the gap between the upper jockey wheel and the cassette cogs.

1. Shift the chain to the largest cog on the cassette.
2. Adjust the B-tension screw until there is a gap of approximately 5-6mm between the top of the largest cog and the top of the upper jockey wheel. This ensures smooth shifting and prevents the jockey wheel from rubbing the cassette.

5. 운영

The microSHIFT Estes RD-M220L derailleur operates in conjunction with a compatible 7, 8, or 9-speed shifter. Shifting is achieved by pulling or releasing the shift cable, which moves the derailleur cage laterally across the cassette.

• Upshifting (to smaller cogs): Press the shifter lever to release cable tension, allowing the derailleur to move the chain to smaller cogs.
• Downshifting (to larger cogs): Press the shifter lever to pull the cable, moving the derailleur to larger cogs.

For optimal performance, avoid shifting under heavy pedaling load. Ease off the pedals slightly during shifts for smoother transitions and to prolong drivetrain component life.

6. 유지관리

정기적인 유지보수는 변속기의 수명 연장과 최적의 성능을 보장합니다.

6.1 청소

• Periodically clean the derailleur body, cage, and jockey wheels with a degreaser and brush.
• 물로 깨끗이 헹구고 완전히 말리세요.

6.2 윤활

• Apply a small amount of bicycle chain lubricant to the pivot points of the derailleur and the jockey wheel bearings.
• Wipe off any excess lubricant to prevent dirt accumulation.

6.3 검사

• 변속기 행어가 휘어졌는지 정기적으로 점검하십시오. 휘어진 행어는 변속 불량의 원인이 될 수 있습니다.
• Inspect jockey wheels for wear. Worn jockey wheels can lead to noisy operation and inefficient shifting. Replace if necessary.
• 모든 볼트가 제대로 조여져 있는지 확인하십시오.
