2. Setup jeung Instalasi
Proper installation of the derailleur pulleys is crucial for optimal shifting performance and component longevity.
Pakakas Diperlukeun
- Appropriate hex key or Torx wrench for derailleur cage bolts.
- Clean rag.
- Grease (optional, for bolt threads).
Léngkah-léngkah Instalasi
- Remove Old Pulleys: Using the appropriate tool, carefully unbolt and remove the existing upper and lower derailleur pulleys from the derailleur cage. Note the orientation and position of any washers or spacers.
- Clean Derailleur Cage: Clean any dirt, grease, or debris from the derailleur cage where the pulleys mount.
- Identify Pulleys: The pulley set includes an upper and a lower pulley. The upper pulley is often labeled "UPPER" or "GUIDE" and may have a slightly different design (e.g., less lateral play) to aid in shifting. The lower pulley is typically labeled "LOWER" or "TENSION". Ensure correct identification.
- Install New Pulleys:
- Place the new upper pulley into its designated position on the derailleur cage.
- Re-use your existing bolts and washers if they are in good condition, as the included washers may vary or be intended for specific applications. Ensure the washers are correctly positioned on either side of the pulley.
- Insert the bolt and tighten it to the manufacturer's recommended torque specifications (refer to your derailleur's specific manual if available). Do not overtighten.
- Repeat the process for the lower pulley.
- Check Directionality: Some pulleys are directional. Ensure that any arrows or markings on the pulleys indicate the correct direction of chain rotation. Incorrect orientation can lead to poor shifting or premature wear.
- Verify Function: Once installed, manually rotate the crank to ensure the chain runs smoothly through the pulleys and that shifting is precise across all gears. Adjust derailleur limits and cable tension if necessary.

3. Prinsip Operasi
The SRAM Force/Rival/Apex 10 Speed Rear Derailleur Pulley Set is engineered to guide the bicycle chain smoothly through the rear derailleur mechanism. The upper pulley (guide pulley) helps position the chain precisely for gear changes, while the lower pulley (tension pulley) maintains appropriate chain tension. The sealed cartridge bearings minimize friction and contribute to efficient power transfer and consistent shifting.
4. Pangropéa
Regular maintenance extends the lifespan of your derailleur pulleys and ensures optimal performance.
beberesih
- Periodically clean the pulleys with a degreaser and a brush to remove accumulated dirt and grime.
- Bilas tuntas jeung garing sagemblengna.
Lubrication
- While the sealed cartridge bearings require minimal maintenance, ensure the chain is properly lubricated, as this directly affects pulley wear.
- Avoid spraying lubricants directly into the bearing seals, as this can wash out the internal grease.
Pamariksaan
- Regularly inspect the pulley teeth for wear (e.g., "shark fin" profile). Worn teeth can lead to poor shifting and chain skip.
- Check for any cracks in the pulley material, especially around the bearing area.
- Ensure the pulleys spin freely without excessive play or grinding noises.
- Replace pulleys if significant wear or damage is observed.
5. Cara ngungkulan
| Gejala | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Poor or inconsistent shifting | Worn pulley teeth, incorrect pulley installation (e.g., wrong direction, loose bolts), dirty pulleys, worn bearings. | Inspect pulleys for wear and replace if necessary. Verify correct installation and torque. Clean pulleys thoroughly. Check derailleur adjustment. |
| Noise from derailleur area | Dirty pulleys, worn bearings, loose pulley bolts, chain rubbing on cage. | Clean pulleys. Inspect bearings for smooth rotation; replace if rough. Tighten pulley bolts to spec. Check chain line and derailleur alignment. |
| Pulleys cracking or breaking | Impact damage, material fatigue (especially in older designs with cut-outs), overtightening. | Replace pulleys. Ensure proper torque during installation. Consider upgrading to more robust designs if previous pulleys failed due to design flaws. |
