- Potong Kabel Lebihan: Once shifting is properly adjusted, trim any excess shift cable, leaving approximately 2-3 cm beyond the pinch bolt. Install a cable end cap to prevent fraying.
4. Arahan Operasi
The microSHIFT DS85 twist shifter provides intuitive gear changes for your 8-speed drivetrain.
- Shifting Up (Harder Gear): To shift to a higher gear (smaller cog on the rear cassette, making pedaling harder), twist the grip portion of the shifter forward (away from you).
- Shifting Down (Easier Gear): To shift to a lower gear (larger cog on the rear cassette, making pedaling easier), twist the grip portion of the shifter backward (towards you).
- Optical Gear Indicator: Observe the optical gear indicator window to confirm your current gear selection. The number displayed corresponds to the gear you are in.
- Smooth Shifting: For best results, ease off the pedal pressure slightly while shifting. Avoid shifting under heavy load.
