1. Вовед

This manual provides essential information for the proper installation, operation, and maintenance of your SRAM Apex 1 Rear Derailleur. Designed for 1x (single chainring) drivetrains, the Apex 1 derailleur offers reliable and precise shifting performance for various cycling disciplines, including road, gravel, and cyclocross. Its long cage design accommodates a wide range of cassette sizes, and features like the Roller Bearing Clutch and Exact Actuation technology ensure consistent chain tension and crisp shifts.

2. Карактеристики на производот

• Pulleys have sealed cartridge bearings for smooth operation and durability.
• Roller Bearing Clutch and parallelogram design combine to minimize chain bounce, making the drivetrain safer and quieter over rough terrain.
• Not compatible with multiple chainring drivetrains; designed specifically for 1x setups.
• Aluminum cage and parallelogram construction for a balance of strength and weight.

3. Информации за безбедност

Always prioritize safety when working with bicycle components. Incorrect installation or adjustment can lead to serious injury or damage to your bicycle. If you are unsure about any step, consult a qualified bicycle mechanic.

• Wear appropriate safety gear, including eye protection, during installation and maintenance.
• Ensure your bicycle is stable and secure in a work stand before beginning any work.
• Keep hands and clothing clear of moving parts, especially the chain and cogs, when the wheel is spinning.
• Regularly inspect your derailleur and drivetrain for wear, damage, or loose components.

4. Содржина на пакетот

Your SRAM Apex 1 Rear Derailleur package should contain the following:

• SRAM Apex 1 Rear Derailleur (Long Cage)
• Упатство за употреба (овој документ)

Please check all contents upon receipt. If any items are missing or damaged, contact your retailer.

5. Поставување и инсталација

Proper installation is crucial for optimal performance. This section provides general guidelines. Refer to detailed SRAM technical manuals for specific torque specifications and precise adjustment procedures.

5.1. Потребни алатки

• Hex wrenches (typically 5mm)
• Кабелски секачи
• Вртежен клуч (се препорачува)

5.2. Mounting the Derailleur

Thread the derailleur onto the derailleur hanger. Ensure it is fully seated and tighten the mounting bolt to the manufacturer's specified torque. A torque wrench is highly recommended to prevent overtightening or undertightening.

5.3. Cable Routing and Attachment

Route the shift cable through the frame and housing to the derailleur. Secure the cable to the derailleur's cable anchor bolt, ensuring proper tension. Trim excess cable and install a cable end cap.

5.4. Limit Screw Adjustment

Adjust the High (H) and Low (L) limit screws to prevent the chain from shifting beyond the smallest and largest cogs, respectively. This protects the chain from falling off the cassette and prevents damage to the derailleur or spokes.

5.5. B-Tension Adjustment

The B-tension screw adjusts the gap between the upper guide pulley and the cassette cogs. Proper B-tension is critical for smooth shifting across the entire cassette range. Adjust according to SRAM's specific guidelines for your cassette size.

6. Упатства за работа

The SRAM Apex 1 Rear Derailleur is designed for 1x drivetrains, meaning you only have a single shifter for the rear gears. Shifting is intuitive and precise.

6.1. Менување брзини

Use your compatible SRAM 1x shifter to change gears. Pushing the lever in one direction will shift the chain to a larger cog (easier gear), and pushing it in the other direction will shift to a smaller cog (harder gear). Always pedal forward while shifting to ensure smooth transitions and prevent damage to the drivetrain.

6.2. Roller Bearing Clutch Engagement

The Roller Bearing Clutch helps manage chain tension and prevent chain slap. It is always engaged during riding. There is no manual on/off switch for this feature on the Apex 1 derailleur.

7. Одржување

Regular maintenance extends the life of your derailleur and ensures consistent performance.

• Чистење: After each ride, especially in dirty or wet conditions, clean the derailleur body, cage, and pulleys. Use a mild degreaser and a brush, then rinse thoroughly.
• Подмачкување: Apply a small amount of chain lubricant to the pivot points of the derailleur and the pulley bearings periodically. Avoid over-lubrication, which can attract dirt.
• Cable and Housing: Inspect shift cables and housing for fraying, kinks, or corrosion. Replace them if necessary, as damaged cables can significantly impair shifting performance.
• Инспекција на макара: Check the pulley wheels for wear or damage. Worn pulleys can lead to poor shifting and increased drivetrain noise. Replace them if the teeth appear sharp or hooked.
• Hanger Alignment: A bent derailleur hanger is a common cause of poor shifting. If shifting issues persist after other adjustments, have your hanger checked and aligned by a professional.
