3. Configuració i instal·lació
Eines necessàries:
- Clau dinamométrica
- 8mm Hex Key (for crank bolt)
- Appropriate Bottom Bracket Tool (specific to your DUB bottom bracket)
- Greix
- Threadlocker (e.g., Loctite 242, if specified by SRAM for certain bolts)
Comprovacions prèvies a la instal·lació:
- Ensure your frame's bottom bracket shell is clean and faced correctly.
- Confirm you have the correct SRAM DUB bottom bracket installed for your frame.
- Verify that your direct mount chainring or spider is compatible with the SRAM 8-bolt interface.
Passos d'instal·lació:
- Install Chainring/Spider: If not already installed, attach your direct mount chainring or spider to the right crank arm (with integrated spindle) using the 8-bolt interface. Apply threadlocker to the bolts as per SRAM's recommendations and torque them to the specified value (typically 10-12 Nm).
- Grease Spindle: Apply a thin layer of high-quality grease to the DUB spindle.
- Install Right Crank Arm: Carefully slide the right crank arm (with chainring/spider) through the DUB bottom bracket from the drive side of the bicycle.
- Install Left Crank Arm: Align the splines of the left crank arm with the splines on the spindle. Push the left crank arm onto the spindle until it seats fully.
- Tighten Crank Bolt: Insert the 8mm hex key into the main crank bolt on the non-drive side. Tighten the crank bolt to the specified torque value. For SRAM DUB cranksets, this is typically 54 Nm (480 in-lb). Ensure the crank arms are securely fastened and spin freely without play.
- Comprovació final: Rotate the crankset to ensure smooth operation and check for any lateral play.
4. Consideracions operatives
Once installed, the SRAM Force AXS D1 Crankset operates as a standard bicycle crankset. Ensure your chain is compatible with your chainring and drivetrain system. For optimal shifting performance, especially with AXS components, ensure proper chain length and derailleur adjustment.
- Avoid cross-chaining excessively, as this can increase wear on the chainring and chain.
- Regularly check the tightness of the crank bolt and chainring bolts.
5. Manteniment
Regular maintenance will extend the life and performance of your SRAM Force AXS D1 Crankset.
Neteja:
- Clean the crankset regularly with mild soap and water, especially after riding in wet or dirty conditions.
- Avoid using high-pressure washers directly on the bottom bracket area, as this can force water and contaminants into the bearings.
- Dry the crankset thoroughly after cleaning.
Inspecció:
- Periodically inspect the carbon crank arms for any signs of damage, cracks, or delamination. If damage is found, discontinue use immediately and consult a qualified bicycle mechanic.
- Check chainring teeth for excessive wear (e.g., shark-finning). Replace worn chainrings to maintain shifting performance and prevent chain slip.
- Ensure all bolts (crank bolt, chainring bolts) are torqued to specification.
Lubricació:
- Ensure your bottom bracket bearings are running smoothly. If they feel rough or gritty, they may need servicing or replacement.
- Apply a small amount of grease to pedal threads before installing pedals to prevent seizing.
6. Solució De Problemes
Problemes comuns i solucions:
| Problema | Causa possible | Solució |
|---|---|---|
| Creaking noise from crank area | Loose crank bolt, dry bottom bracket threads, worn bottom bracket bearings, loose chainring bolts. | Check and re-torque crank bolt and chainring bolts. Remove, clean, grease, and re-install bottom bracket. Replace worn bottom bracket bearings. |
| Crank arms feel loose or have play | Loose crank bolt, incorrect bottom bracket spacers (if applicable). | Re-torque crank bolt to specification. Consult your bottom bracket instructions for correct spacer configuration. |
| Poor shifting performance (front) | Worn chainring, incorrect chain line, misaligned front derailleur. | Inspect and replace worn chainring. Verify correct chain line. Adjust front derailleur. |
If you encounter issues not listed here or are unable to resolve a problem, please consult a qualified bicycle mechanic or contact SRAM customer support.
