Persediaan dan Pemasangan

1. Mounting the Shift/Brake Levers

1. Position the left and right shift/brake lever units on your bicycle handlebars. Ensure they are placed comfortably for easy reach of both the brake levers and shifter paddles.
2. Ketatkan clamp bolts securely. Do not overtighten. Refer to your bicycle's handlebar specifications for recommended torque.

2. Cable Routing and Cutting

• Route the shifter and brake cables through the appropriate guides on your bicycle frame. Ensure smooth, unhindered paths for the cables.
• Measure and cut the cable housing to the correct lengths. Use a specialized cable cutter or a rotary tool (such as a Dremel with a cut-off wheel) to ensure clean, unfrayed cuts. Clean the ends of the housing to prevent internal friction.
• Install ferrules on the ends of the cable housing.

3. Connecting Brake Cables

1. Insert the brake inner wire through the brake lever unit and housing.
2. Attach the brake cable to your V-brakes or cantilever brakes according to the brake manufacturer's instructions.
3. Adjust the brake lever reach if necessary. The ST-EF65 features adjustable brake lever reach.
4. Brake Type Compatibility: The ST-EF65 is compatible with both V-brakes and cantilever brakes. An internal adjustment mechanism within the lever allows switching between brake types. Refer to the detailed diagram or instructions provided with the product for this specific adjustment.

4. Connecting Shifter Cables

1. Insert the shifter inner wire through the shifter unit and housing.
2. Attach the front shifter cable to your front derailleur and the rear shifter cable to your rear derailleur.
3. Adjust the derailleur limits and cable tension according to the derailleur manufacturer's instructions. This is crucial for precise shifting.

Arahan Operasi

Menukar Gear

• The ST-EF65 uses a trigger-style shifting mechanism.
• To shift to a larger gear (harder pedaling), press the larger lever with your thumb.
• To shift to a smaller gear (easier pedaling), pull the smaller lever with your index finger.
• Yang bersepadu optical gear display window provides a visual indication of the current gear selection.
• Always shift gears while pedaling forward with light pressure to ensure smooth transitions. Avoid shifting under heavy load.

Brek

• Squeeze the brake levers towards the handlebar to engage the brakes.
• Apply both front and rear brakes simultaneously for controlled stopping.
• Adjust brake lever reach for comfortable and effective braking.

Penyelenggaraan

• Pembersihan: Keep the shift/brake levers clean from dirt and debris. Use a damp cloth and mild soap if necessary. Avoid high-pressure washing directly on the components.
• Pelinciran Kabel: Periodically apply a small amount of bicycle-specific cable lubricant to the inner wires where they enter the housing. This reduces friction and improves shifting/braking performance.
• Cable and Housing Inspection: Regularly check shifter and brake cables and housing for signs of wear, fraying, kinks, or corrosion. Replace damaged cables and housing promptly to maintain safety and performance.
• Brake Pad Inspection: Inspect your brake pads regularly for wear. Replace them before they wear past their wear indicators to ensure effective braking.
• Keketatan Bolt: Periodically check the tightness of all mounting bolts on the shift/brake levers and brake calipers/cantilevers.

Menyelesaikan masalah

Shifting Issues

• Gears not shifting smoothly or skipping: Check cable tension. Too loose or too tight can cause issues. Adjust the barrel adjuster on the shifter or derailleur. Ensure derailleur limit screws are correctly set. Inspect cables and housing for friction or damage.
• Shifter not engaging: Check for debris obstructing the shifting mechanism. Ensure the cable is properly seated in the shifter.

Isu Brek

• Weak braking power: Check brake pad wear and alignment. Ensure brake cables are properly tensioned and free of friction. Verify the brake type adjustment within the lever is correct (V-brake vs. cantilever).
• Spongy brake feel: This often indicates excessive cable friction or improper cable routing. Inspect housing for kinks or damage.
• Brakes rubbing: Check brake caliper/cantilever alignment. Ensure brake levers return fully to their resting position.
