Setup and Installation
Proper installation is crucial for optimal performance and longevity of your microSHIFT R10 Rear Derailleur. It is recommended that installation be performed by a qualified bicycle mechanic.
Tools Required:
- Hex key set (typically 5mm for mounting bolt)
- Cable cutters
- Cable crimps
- Torque wrench (recommended for precise installation)
Installation Steps:
- Mounting the Derailleur: Attach the derailleur to the derailleur hanger on your bicycle frame. Ensure the B-tension screw is correctly positioned against the hanger tab. Tighten the mounting bolt to the manufacturer's recommended torque specification.
- Routing the Cable: Route the shift cable from your shifter through the frame's cable guides and into the derailleur's cable anchor bolt. Ensure the cable is free of kinks and excessive friction.
- Securing the Cable: Pull the cable taut and secure it under the cable anchor bolt. Do not overtighten. Trim excess cable and install a cable crimp to prevent fraying.
- Limit Screw Adjustment:
- High Limit (H) Screw: Adjust the H-screw to prevent the chain from shifting beyond the smallest cog. The guide pulley should align directly under the smallest cog.
- Low Limit (L) Screw: Adjust the L-screw to prevent the chain from shifting beyond the largest cog and into the spokes. The guide pulley should align directly under the largest cog.
- B-Tension Adjustment: With the chain on the largest cog and smallest chainring, adjust the B-tension screw to set the gap between the upper guide pulley and the largest cog. A gap of 5-6mm is generally recommended, but refer to specific drivetrain recommendations for optimal performance.
Operating Instructions
The microSHIFT R10 Rear Derailleur operates by moving the chain across the rear cassette cogs in response to input from your shift lever. This derailleur is designed for smooth and precise 10-speed shifting.
Shifting Procedure:
- Always pedal forward while shifting. Avoid shifting under heavy load.
- To shift to a larger cog (easier gear), actuate the appropriate shift lever. The derailleur will move inward.
- To shift to a smaller cog (harder gear), actuate the appropriate shift lever. The derailleur will move outward.
- Listen for smooth shifts. If shifting is hesitant or noisy, cable tension adjustment may be required.
Cable Tension Adjustment (Fine-Tuning):
Minor adjustments to cable tension can be made using the barrel adjuster located on the derailleur or shifter.
- If shifting to larger cogs is slow or hesitant, turn the barrel adjuster counter-clockwise (out) to increase cable tension.
- If shifting to smaller cogs is slow or hesitant, turn the barrel adjuster clockwise (in) to decrease cable tension.
Maintenance
Regular maintenance extends the life and ensures the performance of your derailleur.
Cleaning:
- Periodically clean the derailleur body, jockey wheels, and cage with a degreaser and brush. Rinse thoroughly and dry.
- Ensure no grit or grime accumulates around the pivots.
Lubrication:
- Apply a small amount of bicycle-specific lubricant to the pivot points of the derailleur and the jockey wheel bearings.
- Avoid over-lubrication, which can attract dirt.
Inspection:
- Regularly check for bent derailleur hangers, which can cause poor shifting.
- Inspect jockey wheels for wear; replace if teeth are excessively worn or damaged.
- Check cable and housing for fraying, kinks, or contamination. Replace as needed.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow or hesitant shifting to larger cogs | Insufficient cable tension; dirty/frayed cable or housing | Increase cable tension with barrel adjuster (counter-clockwise); clean or replace cable/housing. |
| Slow or hesitant shifting to smaller cogs | Excessive cable tension; dirty/frayed cable or housing | Decrease cable tension with barrel adjuster (clockwise); clean or replace cable/housing. |
| Chain overshifts past smallest cog | H-limit screw set too far out | Turn H-limit screw clockwise (in) until chain aligns with smallest cog. |
| Chain overshifts past largest cog (into spokes) | L-limit screw set too far out | Turn L-limit screw clockwise (in) until chain aligns with largest cog. |
| Noisy shifting or poor chain wrap | Incorrect B-tension adjustment; bent derailleur hanger | Adjust B-tension screw; inspect and straighten/replace derailleur hanger. |
