セットアップとインストール

Proper installation is crucial for optimal performance and safety. If you are unsure about any steps, consult a professional bicycle mechanic.

必要なツール

  • Hex Key Set (e.g., 5mm)
  • ケーブルカッター
  • Chain Tool (if replacing chain)
  • トルクレンチ（推奨）

インストール手順

  1. ディレイラーの取り付け： Attach the derailleur to the derailleur hanger on your bicycle frame. Ensure it is securely tightened to the manufacturer's recommended torque specification.
  2. ケーブル配線: Route the derailleur cable from your shifter to the derailleur. Ensure the cable runs smoothly without kinks or excessive friction.
  3. ケーブルアタッチメント: Secure the derailleur cable to the derailleur's cable fixing bolt. Pull the cable taut before tightening the bolt.
  4. チェーンの取り付け: If installing a new chain, ensure it is the correct length for your drivetrain. Route the chain through the derailleur pulleys.
  5. リミットスクリュー調整:
    • 上限（H）ネジ： Adjust the H-screw to prevent the chain from shifting beyond the smallest cog and into the frame.
    • 下限（L）ネジ： Adjust the L-screw to prevent the chain from shifting beyond the largest cog and into the spokes.
  6. Bテンション調整: Adjust the B-tension screw to set the proper distance between the upper guide pulley and the cogs. This ensures smooth shifting across all gears.
  7. Indexing Adjustment: Fine-tune the cable tension using the barrel adjuster on the shifter or derailleur to ensure precise shifting across all gears. Shift through all gears to confirm smooth operation.
