1. Handlebar Mounting

1. Ensure your handlebars are clean and free of grease.
2. Slide the shift levers onto the handlebars from the ends. Position them ergonomically for comfortable reach to both brake and shift levers.
3. Tighten the clamp bolts (usually located under the hood) to secure the levers. Refer to your handlebar manufacturer's specifications for torque settings, typically around 5-7 Nm.

2. Cable Routing (External)

The R8 levers feature external shift cable routing for ease of installation and maintenance.

1. Locate the shift cable entry port on the lever body, typically under the hood.
2. Insert the shift cable head into the lever mechanism.
3. Route the shift cable through the provided housing. Ensure the housing length is appropriate, allowing for smooth handlebar turning without kinking.
4. Connect the shift cable to the front and rear derailleurs according to their respective manufacturer's instructions.
5. Secure the cable with the derailleur's pinch bolt and trim excess cable, leaving a few centimeters for adjustment. Install a cable end cap.

2. Route the brake cable through the brake housing.
3. Connect the brake cable to your caliper or cantilever brakes.
4. Adjust brake tension and ensure proper brake function before riding.

Operating Instructions

The microSHIFT R8 levers feature a separate dedicated lever for up- and down-shifts.

• Shifting Up (to a larger cog/chainring): Push the main shift lever (the larger paddle behind the brake lever) inwards towards the handlebar.
• Shifting Down (to a smaller cog/chainring): Push the smaller lever (located just below the main shift lever) inwards towards the handlebar.
• Braking: Pull the main brake lever towards the handlebar.

Always shift smoothly and avoid excessive force. Practice shifting while stationary before riding to become familiar with the lever action.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your microSHIFT R8 levers.

• Cleaning: Wipe down the levers and hoods with a damp cloth. Avoid harsh chemicals that may damage the finish or rubber.
• Cable Inspection: Periodically check shift and brake cables for fraying, rust, or kinks. Replace cables and housing if any damage is observed or if shifting/braking performance degrades. The external routing makes cable replacement straightforward.
• Hood and Face Plate: The R8 levers feature replaceable hood covers and face plates. If these components become worn or damaged, they can be replaced to restore appearance and grip.
• Lubrication: Apply a small amount of bicycle-specific lubricant to the pivot points of the levers and where cables enter the housing to ensure smooth operation.
