2. Información de seguridade

Always prioritize safety when working with bicycle components. Improper installation or maintenance can lead to serious injury or damage to your bicycle.

It is highly recommended to have this component installed by a qualified bicycle mechanic.
Always wear appropriate safety gear, including eye protection and gloves, when performing installation or maintenance.
Ensure all bolts and fasteners are tightened to the manufacturer's specified torque settings. Overtightening can strip threads, while undertightening can lead to components loosening during use.
Regularly inspect your shifter and associated cables for wear, damage, or corrosion. Replace worn parts immediately.
Do not modify the shifter or its components. Use only genuine microSHIFT replacement parts.
Before riding, always perform a pre-ride safety check to ensure all components are functioning correctly and securely.

4. Configuración e instalación

The microSHIFT AMBIO 7V Twist Shifter is designed for easy installation. However, if you are unsure about any step, consult a professional bicycle mechanic.

Ferramentas necesarias:

Hex key set (typically 4mm or 5mm for clamp bolt)
Cortadores de cable
Crimpadoras de cables
Graxa (para os extremos da carcasa do cable)

Pasos de instalación:

Eliminar compoñentes antigos: If replacing an existing shifter, carefully remove the old grip and shifter from the handlebar. Disconnect the shift cable from the rear derailleur and pull it through the housing.
Preparar o manillar: Asegúrate de que a zona do manillar onde se montará a palanca de cambios estea limpa e libre de residuos.
Mount Shifter: Slide the microSHIFT AMBIO 7V Twist Shifter onto the handlebar. Position it comfortably for easy access and operation. The shifter is typically mounted on the right side for rear gears.
Secure Shifter: Use a hex key to tighten the clamp bolt on the shifter. Do not overtighten; ensure it is secure enough not to rotate during riding but can still be adjusted if needed.
Instalar o cable de cambio:
- Route the new shift cable through the shifter body (if not pre-installed).
- Feed the cable through the appropriate cable housing and frame guides, leading it to the rear derailleur. Ensure cable routing is smooth and free of sharp bends.
- Attach the cable to the rear derailleur's cable anchor bolt. Pull the cable taut and tighten the anchor bolt.
Adjust Derailleur: Perform initial derailleur adjustments to ensure smooth shifting across all 7 gears. This typically involves setting the high (H) and low (L) limit screws and adjusting cable tension using the barrel adjuster on the shifter or derailleur. Refer to your derailleur's specific manual for detailed adjustment procedures.
Trim Cable and Crimp: Once shifting is satisfactory, trim the excess shift cable, leaving about 2-3 cm beyond the anchor bolt. Install a cable crimp on the end of the cable to prevent fraying.
Install Grip: Slide your handlebar grip onto the handlebar, next to the shifter.

5. Instrucións de funcionamento

The microSHIFT AMBIO 7V Twist Shifter provides intuitive control over your bicycle's 7-speed rear drivetrain.

Shifting Up (Harder Gears): To shift to a harder (smaller) gear, twist the shifter grip towards the front of the bicycle (clockwise when viewed from the rider's perspective). The numbers on the shifter will indicate the current gear.
Shifting Down (Easier Gears): To shift to an easier (larger) gear, twist the shifter grip towards the rear of the bicycle (counter-clockwise when viewed from the rider's perspective).
Pedaling While Shifting: Always pedal lightly while shifting gears. Applying too much pressure during a shift can cause chain skipping, damage to the drivetrain, or an inefficient shift.
Index Shifting: The shifter operates with an indexing mechanism, meaning each twist clicks into a specific gear position, ensuring precise shifts.

6. Mantemento

Regular maintenance will prolong the life and ensure optimal performance of your microSHIFT AMBIO 7V Twist Shifter.

Limpeza: Keep the shifter and surrounding handlebar area clean. Wipe down with a damp cloth. Avoid using harsh chemicals that could damage plastic or rubber components.
Inspección de cables: Periodically inspect the shift cable for fraying, rust, or kinks. A damaged cable can lead to poor shifting performance. Replace cables annually or more frequently if you ride in wet or dirty conditions.
Lubricación de cables: Apply a small amount of light lubricant to the shift cable where it enters the housing and at the derailleur. This reduces friction and improves shifting smoothness.
Shifter Function Check: Regularly check that the shifter twists smoothly and clicks positively into each gear. If it feels stiff or imprecise, check cable tension and routing.
Apertura dos parafusos: Ensure the shifter's clamp bolt remains securely tightened.
