2. ข้อมูลด้านความปลอดภัย

Always prioritize safety when installing, operating, or maintaining bicycle components. Improper installation or adjustment can lead to serious injury or damage to your bicycle. If you are unsure about any step, consult a professional bicycle mechanic.

• Wear appropriate safety gear, including eye protection, during installation and maintenance.
• ตรวจสอบให้แน่ใจว่าได้ขันน็อตทุกตัวแน่นตามค่าแรงบิดที่ผู้ผลิตกำหนดไว้แล้ว
• Keep hands and clothing clear of moving parts, especially the chain and chainrings, during operation.
• Regularly inspect the derailleur and associated components for wear, damage, or loose connections.

3. การตั้งค่าและการติดตั้ง

This section outlines the steps for installing your Sram Braze-On Front Derailleur. Ensure your bicycle frame has a compatible braze-on mount.

3.1. เครื่องมือที่จำเป็น

• ชุดประแจหกเหลี่ยม (โดยทั่วไปจะมีขนาด 2 มม., 4 มม., 5 มม.)
• คีมตัดสายไฟ
• Torque wrench (recommended for precise tightening)
• จาระบีหรือสารป้องกันการติดขัด

3.2. ขั้นตอนการติดตั้ง

1. Prepare the Braze-On Mount: Clean the braze-on mount on your frame. Apply a thin layer of grease or anti-seize compound to the mounting bolt threads.
2. Mount the Derailleur: Position the derailleur onto the braze-on mount. Insert the mounting bolt and hand-tighten it. Ensure the derailleur cage is parallel to the large chainring.
3. Adjust Derailleur Angle (Yaw): If your derailleur features Yaw technology, rotate the derailleur body around the braze-on bolt until the rear of the derailleur cage is angled slightly inward (towards the frame) when viewed from above. This angle will become parallel to the chain when shifted to the large chainring.
4. Tighten Mounting Bolt: Securely tighten the mounting bolt to the manufacturer's specified torque (refer to Sram's official documentation for exact torque values, typically around 5-7 Nm).
5. เส้นทางสายเคเบิล: Route the derailleur cable from the shifter through the frame's cable guides to the derailleur's cable anchor bolt. Ensure the cable runs smoothly without kinks.
6. Attach and Tension Cable: Pull the cable taut and secure it under the cable anchor bolt. Tighten the anchor bolt to the specified torque.
7. Set Limit Screws: Adjust the High (H) and Low (L) limit screws to prevent the chain from over-shifting off the chainrings. The H-screw controls the outward movement (large chainring), and the L-screw controls the inward movement (small chainring).
8. ปรับความตึงสายเคเบิลอย่างละเอียด: Use the barrel adjuster on the shifter or derailleur to fine-tune cable tension for crisp shifting.

4. Operating the Derailleur

The Sram front derailleur is designed for intuitive and efficient gear changes. Use your left shifter to move the chain between the front chainrings.

• Shifting Up (to a larger chainring): Push the shifter lever to move the chain from a smaller chainring to a larger one. This typically requires a longer lever throw.
• Shifting Down (to a smaller chainring): Push the release lever to move the chain from a larger chainring to a smaller one. This typically requires a shorter lever throw.
• Cross-Chaining: Avoid extreme gear combinations (e.g., large front chainring with large rear cog, or small front chainring with small rear cog) as this can cause excessive chain wear and noise.

5. การบำรุงรักษา

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

5.1. การทำความสะอาด

• Clean the derailleur regularly with a mild degreaser and a brush to remove dirt and grime.
• ล้างออกด้วยน้ำสะอาดแล้วเช็ดให้แห้งสนิท

5.2. การหล่อลื่น

• Apply a small amount of bicycle-specific lubricant to the pivot points of the derailleur.
• Avoid over-lubricating, as this can attract more dirt.

5.3. การตรวจสอบและปรับแต่ง

• Periodically check the derailleur for any signs of damage, bending, or excessive play.
• Ensure the mounting bolt is secure and tightened to the correct torque.
• Check cable tension and adjust using the barrel adjuster if shifting becomes sluggish or imprecise.
• Verify that the limit screws are still correctly set to prevent over-shifting.
