Proper installation is crucial for optimal performance and safety. If you are unsure about any step, it is recommended to seek assistance from a qualified bicycle mechanic.

2.1 Eines necessàries

• Claus hexagonals (diverses mides)
• Cortacables
• Cable crimps
• Greix
• Clau dinamométrica (recomanada)

2.2 Mounting the Shifters

1. Position the shifters on your handlebar. Ensure they are within comfortable reach for both braking and shifting.
2. Secure the shifters to the handlebar using the appropriate hex wrench. Do not overtighten.
3. Adjust the angle of the shifters for ergonomic comfort.

2.3 Cable and Housing Installation

1. Route the shifter cables through the provided housing. Ensure the housing length is appropriate for your bike, allowing for smooth steering without excessive slack or tension.
2. Insert the cable ends into the shifter mechanisms.
3. Connect the cables to your front and rear derailleurs.
4. Adjust cable tension at the derailleurs to ensure proper shifting. Refer to your derailleur's specific instructions for detailed adjustment procedures.
5. Trim excess cable length, leaving approximately 2-3 cm beyond the derailleur anchor bolt. Install cable crimps on the cable ends to prevent fraying.

Nota: The SL-R440-8 shifters are designed for 8-speed systems. Ensure your cassette and derailleurs are compatible with an 8-speed setup. The front shifter offers trim adjustments for 2x or 3x chainring configurations.

3. Instruccions de funcionament

The SHIMANO SL-R440-8 shifters utilize a Rapidfire Plus mechanism for quick and precise gear changes.

3.1 Canviant de marxa

• Upshifting (to a larger cog/chainring): Use the larger lever (typically operated by the thumb) to push the cable, moving the derailleur to a larger gear.
• Downshifting (to a smaller cog/chainring): Use the smaller lever (typically operated by the index finger) to release cable tension, moving the derailleur to a smaller gear.
• Multi-Shift Function: Rapidfire Plus shifters allow for multiple gear changes with a single sweep of the lever.

Always shift gears while pedaling forward with moderate pressure. Avoid shifting under heavy load or while stationary to prevent damage to your drivetrain components.

4. Manteniment

Regular maintenance will prolong the life and ensure the smooth operation of your shifters.

4.1 Neteja

• Wipe down the shifter bodies with a clean, damp cloth after rides, especially in dirty or wet conditions.
• Avoid using high-pressure washers directly on the shifters, as this can force water and contaminants into the mechanism.

4.2 Lubricació

• Periodically apply a small amount of light lubricant to the pivot points of the shifter levers.
• Inspect shifter cables for fraying or corrosion. Replace cables and housing annually, or more frequently if you ride in harsh conditions, to maintain optimal shifting performance.

4.3 Inspecció

• Regularly check that the shifters are securely mounted to the handlebar.
• Ensure cables are free from kinks or damage.
• Verify that shifting is smooth and precise. If shifting becomes sluggish or inconsistent, it may indicate a need for cable adjustment or replacement.
