4.3 Installing the Shifter Cable

1. การเดินสายเคเบิล: Route the shifter cable through the appropriate housing and guides on your bicycle frame, leading to the rear derailleur. Ensure the cable housing is cut to the correct length, allowing for smooth turns without excessive slack or tension.
2. Derailleur Attachment: With the shifter in the highest gear (smallest cog position), pull the cable taut and secure it to the rear derailleur's cable anchor bolt. Tighten the bolt to the manufacturer's specified torque.
3. Cable Trim: Cut the excess cable approximately 2-3 cm (1 inch) beyond the anchor bolt. Install a cable end cap to prevent fraying.

5. คู่มือการใช้งาน

The SRAM GX Rear Trigger Shifter features two levers for intuitive gear changes.

• Upshift (Smaller Cog, Harder Gear): Press the smaller lever with your index finger to shift to a smaller cog on the cassette, making pedaling harder. This shifter is a "single click" design, meaning each press shifts one gear.
• Downshift (Larger Cog, Easier Gear): Press the larger lever with your thumb to shift to a larger cog on the cassette, making pedaling easier. This shifter also operates with a single click per press.

Always pedal forward while shifting to ensure smooth and efficient gear changes. Avoid shifting under heavy load.

6. การบำรุงรักษา

Regular maintenance will prolong the life and performance of your shifter.

• การทำความสะอาด: Keep the shifter body and levers clean from dirt and debris. Use a damp ใช้ผ้าและสบู่เหลวอ่อนๆ เช็ดหากจำเป็น หลีกเลี่ยงสารเคมีรุนแรง
• การตรวจสอบสายเคเบิล: Periodically inspect the shifter cable and housing for signs of wear, fraying, or corrosion. Replace cables and housing as needed to maintain crisp shifting.
• การหล่อลื่น: The internal mechanism of the shifter is generally sealed and does not require regular lubrication. However, ensure the cable runs smoothly through the housing. If friction is detected, consider replacing the cable and housing.
• แรงบิดของสลักเกลียว: Occasionally check the shifter clamp bolt for proper torque.
