Naudojimo instrukcijos
The SRAM X3 Rear Derailleur operates with a 1:1 actuation ratio, providing consistent and reliable shifting. To operate:
- Shifting Up (to a smaller cog): Press the smaller lever or twist the shifter grip to move the chain to a smaller, harder-to-pedal cog. This is typically used for increasing speed on flat terrain or downhill.
- Shifting Down (to a larger cog): Press the larger lever or twist the shifter grip to move the chain to a larger, easier-to-pedal cog. This is ideal for climbing hills or reducing effort.
- Sklandus pavarų perjungimas: Always ease off the pedals slightly when shifting to allow the chain to move smoothly between cogs. Avoid shifting under heavy load.
Priežiūra
Regular maintenance extends the life and performance of your derailleur:
- Valymas: Periodically clean the derailleur, especially the jockey wheels, to remove dirt and grime. Use a degreaser and a brush, then rinse and dry thoroughly.
- Tepimas: Apply a small amount of bicycle-specific lubricant to the pivot points of the derailleur and the chain. Wipe off any excess.
- Kabelis ir korpusas: Inspect the shift cable and housing for fraying, kinks, or corrosion. Replace them if any damage is found to maintain smooth shifting.
- Hanger Alignment: Regularly check the derailleur hanger for alignment. Even minor bends can affect shifting.
- Varžtų sandarumas: Ensure all mounting bolts are securely tightened to prevent movement and ensure safety.
