SRAM GX Bicycle Rear Derailleur 1x11 Speed Long Cage - Instruction Manual

1. บทนำ

The SRAM GX 1x11 Rear Derailleur is engineered to provide reliable 11-speed shifting performance. This component is designed to be compatible with SRAM's 10-42 11-speed cassette, offering a wide range of gears suitable for various cycling conditions. It incorporates SRAM's one-by engineering principles to ensure smooth, accurate, and predictable rear shifts. Key features include offset pulleys with X-Sync profiles for optimal chain engagement, X-HORIZON technology to prevent ghost shifting and reduce shifting force, and a Roller Bearing Clutch for consistent chain tension and drivetrain stability. Sealed cartridge bearings enhance durability, and the integrated Cage Lock design simplifies rear wheel installation and removal.

2. คุณสมบัติหลัก

• High-Performance 11-Speed Shifting: Delivers reliable gear changes with a durable long cage design, optimized for mountain biking and trail riding.
• Type 2.1 Roller Bearing Clutch: Ensures superior chain tension control, reduces ghost shifting, and enhances durability in rugged conditions.
• X-HORIZON Technology: Reduces shift force and eliminates cage slap, providing crisp, precise gear changes for aggressive riding styles and technical terrain.
• โครงสร้างทนทาน: Constructed with a lightweight aluminum cage and steel pulleys, combining strength and lightweight performance for XC, trail, and all-mountain biking.
• Cage Lock Mechanism: Facilitates effortless rear wheel removal and maintenance, making bike repairs quicker and more convenient.

3. การตั้งค่าและการติดตั้ง

Proper installation is crucial for optimal performance. It is recommended to have this component installed by a qualified bicycle mechanic. The following points highlight key aspects of the setup:

1. การติดตั้ง: Securely attach the derailleur to the derailleur hanger on your bicycle frame. Ensure the hanger is straight and aligned.
2. การเดินสายเคเบิล: Route the shifter cable according to your bike's frame design, ensuring smooth, unrestricted movement.
3. สกรูจำกัดระยะ: Adjust the high (H) and low (L) limit screws to prevent the chain from shifting beyond the smallest and largest cogs of your cassette.
4. B-Tension Adjustment: Use the B-tension screw to set the correct gap between the upper derailleur pulley and the largest cog on your cassette. This is critical for smooth shifting across all gears.
5. Chain Gap Tool: Utilize the provided chain gap tool (if included with your specific model or available separately) to achieve the precise B-tension setting for optimal chain clearance and shifting performance.
6. Cage Lock Mechanism: For easier rear wheel installation or removal, engage the Cage Lock by pulling the derailleur cage forward and pressing the button to lock it in place. This releases chain tension. Disengage by pressing the button again.

4. Operating the Derailleur

The SRAM GX derailleur is designed for intuitive and precise shifting. Use your shifter lever to change gears. The X-HORIZON design ensures that the derailleur moves along a straight horizontal axis, which contributes to quick and accurate shifts.

• Upshifting (to harder gears): Typically, a single click on the shifter will move the chain one cog at a time to a harder (smaller) gear.
• Downshifting (to easier gears): The GX shifter allows for multiple downshifts with a single push, enabling you to drop up to three gears at once. This is particularly useful when approaching steep climbs and needing to quickly access an easier gear ratio.

5. การบำรุงรักษา

Regular maintenance will prolong the life and performance of your SRAM GX derailleur:

• การทำความสะอาด: Keep the derailleur, pulleys, and chain clean from dirt and debris. Use a bike-specific cleaner and brush.
• การหล่อลื่น: Regularly lubricate your chain and ensure the derailleur pivots move freely. Avoid over-lubricating the pulleys.
• การตรวจสอบสายเคเบิล: Periodically check the shifter cable and housing for wear, fraying, or contamination. Replace if necessary to maintain crisp shifting.
• Derailleur Hanger Alignment: A bent derailleur hanger is a common cause of poor shifting. Inspect and straighten the hanger if needed.
• Roller Bearing Clutch: The Type 2.1 Roller Bearing Clutch is designed to be low maintenance but ensure it is free of excessive dirt buildup.

6 การแก้ไขปัญหา

If you experience issues with your derailleur, consider the following common troubleshooting steps:

• Skipping Gears or Slow Shifting: Check for cable tension. Use the barrel adjuster on your shifter or derailleur to fine-tune tension. A quarter-turn at a time can make a significant difference. Also, inspect the derailleur hanger for alignment.
• Chain Rubbing: Ensure limit screws are correctly set. If the chain rubs on the derailleur cage, the limit screws might be too tight or too loose.
• เสียงดังเกินไป: Clean and lubricate the chain and pulleys. Check for any loose components or foreign objects caught in the drivetrain.
• Stiff Shifter Lever: Inspect the shifter cable and housing for corrosion or damage. Replace if necessary.

For persistent issues or complex adjustments, it is always recommended to consult a professional bicycle mechanic.
