Proper installation is crucial for optimal performance. If you are unsure about any steps, it is recommended to consult a professional bicycle mechanic.

3.1 Potřebné nástroje

• Hex wrench set (typically 4mm or 5mm for shifter clamp)
• Řezačky kabelů
• Kabelové krimpovací svorky
• Grease (for cable housing ends)

3.2 Montáž řadicí páky

1. Uvolněte třamp bolt on the shifter using the appropriate hex wrench.
2. Slide the shifter onto the left side of your handlebar. Position it comfortably for easy access to the shift levers and optical indicator. Ensure it does not interfere with brake levers or grips.
3. Utáhněte třamp bolt securely. Do not overtighten, as this can damage the shifter or handlebar.

3.3 Cable Installation and Routing

1. Ensure the shifter is in the highest gear (smallest chainring position) by pressing the release lever multiple times.
2. Locate the cable port on the shifter. Insert the shift cable head into the designated slot.
3. Route the cable through the shifter body and out the cable adjustment barrel.
4. Thread the cable through the outer cable housing, ensuring the housing is cut to the correct length and ends are properly prepared (e.g., with ferrules).
5. Route the cable and housing to your front derailleur.
6. Attach the cable to the front derailleur's cable anchor bolt, ensuring proper tension.
7. Cut any excess cable, leaving approximately 2-3 cm, and crimp a cable end cap onto the cable to prevent fraying.

3.4 Adjusting the Front Derailleur

After cable installation, fine-tune your front derailleur according to the manufacturer's instructions. This typically involves adjusting limit screws and cable tension to ensure smooth and precise shifting across all three chainrings.

4. Návod k obsluze

The microSHIFT M759 Marvo LT shifter uses a trigger-style mechanism for intuitive gear changes.

4.1 Shifting Up (Larger Chainring)

To shift to a larger chainring (harder gear), press the longer, main trigger lever towards the handlebar. This action pulls the cable, moving the front derailleur outwards.

4.2 Shifting Down (Smaller Chainring)

To shift to a smaller chainring (easier gear), press the smaller, release trigger lever. This action releases cable tension, allowing the front derailleur to move inwards.

4.3 Optical Gear Indicator

The clear window on top of the shifter displays your current front gear position (1, 2, or 3). This allows for quick visual confirmation of your gear selection.

5. Údržba

Regular maintenance ensures smooth operation and extends the life of your shifter.

• Čištění: Periodically wipe down the shifter body with a clean, damp hadříkem k odstranění nečistot a špíny. Vyhněte se používání agresivních chemikálií.
• Kontrola kabelů: Regularly check the shift cable and housing for signs of wear, fraying, or corrosion. Replace cables and housing as needed to maintain crisp shifting.
• Mazání: Apply a small amount of light lubricant to the pivot points of the shift levers and the cable where it enters the housing to ensure smooth movement. Do not over-lubricate.
• Utahovací moment šroubu: Periodically check the shifter clamp bolt for proper torque. Refer to your bicycle's or component's specifications for recommended torque values.
