Configuración e instalación

Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified bicycle mechanic if you are unfamiliar with bicycle component installation.

Ferramentas necesarias:

• Hex key set (typically 4mm, 5mm)
• Cortadores de cable
• Crimpadoras de cables
• Grease (for bolts)
• Brake and shift cables (included with levers)
• Brake and shift housing (included with levers)

Pasos de instalación:

1. Mounting the Levers:

   Slide the levers onto the handlebars. Position them ergonomically for comfortable reach to both brake and shift levers. Secure the levers using the appropriate hex key, ensuring they are tight enough to prevent rotation but not overtightened (refer to torque specifications if available, typically 6-8 Nm).

2. Brake Cable Installation:

   Insert the brake cable into the lever body. Route the cable through the external routing channels. Connect the cable to your bicycle's brake calipers, ensuring proper tension and alignment. Trim excess cable and install a cable crimp.
3. Shift Cable Installation:

   Insert the shift cable into the lever body. The external shift cable routing facilitates low friction and easy replacement. Route the cable and housing to the front and rear derailleurs. Connect the cables to the derailleurs, ensuring proper tension for smooth shifting. Trim excess cable and install cable crimps.

4. Hood Cover Adjustment:

   Ensure the hood covers are properly seated over the lever bodies. These are replaceable for future maintenance.

5. Axuste inicial:

   Test both braking and shifting functions. Make fine adjustments to cable tension at the derailleurs and brakes to achieve optimal performance. Ensure all gears can be accessed smoothly and brakes engage firmly.

Instrucións de funcionamento

The Microshift R8 Dual Control Levers are designed for intuitive operation, combining braking and shifting functions into a single unit.

Cambio de marchas:

• Upshift (to a larger cog/chainring):

  The upshift is performed by pushing the smaller, inner lever towards the handlebar. This action will move the chain to a larger cog on the rear cassette or a larger chainring on the front crankset, making pedaling easier.
• Downshift (to a smaller cog/chainring):

  The downshift is performed by pushing the main brake lever inwards, away from the handlebar. This action will move the chain to a smaller cog on the rear cassette or a smaller chainring on the front crankset, making pedaling harder but allowing for higher speeds.

• Front Derailleur (Triple System):

  For the 3x8 triple system, the left lever controls the front derailleur. Use the same upshift/downshift actions to move between the three chainrings. Ensure proper trim adjustment to prevent chain rub.

Freado:

To engage the brakes, pull the main lever (the larger lever) towards the handlebar. Apply even pressure for controlled stopping. Avoid sudden, hard braking, especially with the front brake, to prevent loss of control.

Mantemento

Regular maintenance ensures the longevity and optimal performance of your Microshift R8 levers.

• Limpeza:

  Periodically clean the levers and hood covers with a damp cloth. Avoid using harsh chemicals that could damage the plastic or rubber components. Keep the pivot points free of dirt and debris.
• Cable Inspection and Replacement:

  Inspect brake and shift cables regularly for fraying, corrosion, or kinks. Replace cables and housing as needed, especially if shifting or braking performance degrades. The external cable routing makes this process straightforward.

• Hood Cover Replacement:

  The hood covers are replaceable. If they become worn, torn, or sticky, new covers can be installed to restore comfort and grip.

• Lever Pivot Lubrication:

  Apply a small amount of light lubricant to the pivot points of the brake and shift levers to ensure smooth operation. Wipe off any excess lubricant.
