The Shimano HB-5700 [paid link], part of the 105 series, is a front hub renowned for its reliability and performance. Proper installation, adjustment, and maintenance are crucial to ensure optimal functionality and longevity. This guide provides a comprehensive walkthrough for cyclists and mechanics aiming to master the HB-5700 [paid link] hub.
Installation of the Shimano HB-5700 [paid link] Hub
Preparation and Tools Required
Before beginning the installation, gather the following tools:
- 5 mm Allen key
- 15 mm cone wrench [paid link]
- High-quality bicycle grease
- Clean cloths
- Torque wrench [paid link]
Installation Steps
- Wheel Lacing: Begin by lacing the hub into the wheel rim. Ensure that the spoke tension is uniform to maintain wheel integrity and performance.
- Hub Axle Preparation: Apply a thin layer of grease to the hub axle to facilitate smooth operation and prevent corrosion.
- Cone and Locknut Adjustment: Thread the cone onto the axle, followed by the locknut. Using the 15 mm cone wrench [paid link] and 5 mm Allen key, adjust the cone to eliminate any play while ensuring the hub rotates freely. Tighten the locknut securely against the cone to maintain this adjustment.
- Fork Installation: Insert the wheel into the front fork, ensuring the axle is seated correctly in the dropouts. Tighten the quick-release skewer, verifying that the wheel is centered and secure.
Adjustment of the HB-5700 Hub
Bearing Adjustment
Proper bearing adjustment is vital for smooth wheel rotation and hub longevity.
- Initial Assessment: Spin the wheel and check for smoothness. If there is resistance or roughness, an adjustment is necessary.
- Cone Adjustment: Loosen the locknut while holding the cone stationary with the cone wrench [paid link]. Adjust the cone incrementally to achieve a balance where there is no lateral play, and the wheel spins freely.
- Securing the Adjustment: Once optimal adjustment is achieved, hold the cone in place and tighten the locknut securely against it. Recheck the wheel spin to confirm the adjustment remains correct.
Maintenance of the HB-5700 Hub
Regular maintenance ensures the hub’s performance and extends its service life.
- Scheduled Maintenance: Perform hub maintenance every 6,000 to 12,000 kilometers, depending on riding conditions.
- Disassembly: Remove the wheel from the fork. Using the 5 mm Allen key and cone wrench, disassemble the axle by removing the locknut and cone. Carefully extract the bearings, noting their arrangement.
- Cleaning: Wipe all components, including cones, bearings, and the interior of the hub shell, with a clean cloth to remove old grease and contaminants.
- Inspection: Examine bearings for signs of wear or pitting. Inspect the cones and races inside the hub shell for damage. Replace any worn components to prevent further issues.
- Re-greasing: Apply a generous layer of high-quality bicycle grease to the bearings and races.
- Reassembly: Reinsert the bearings into the hub shell, followed by the axle. Thread the cone and locknut back onto the axle, adjusting as previously described to ensure proper bearing preload.
- Final Check: After reassembly, spin the wheel to ensure smooth operation. Verify there is no lateral play and that the wheel is securely fastened in the fork.
Troubleshooting Common Set-Up Issues
Addressing common issues ensures optimal hub performance.
- Excessive Play: If lateral movement is detected, readjust the cone and locknut to eliminate play while maintaining smooth rotation.
- Rough Rotation: Roughness during wheel spin may indicate overly tight bearing adjustment or contaminated bearings. Reassess bearing preload and inspect bearings for wear or contamination.
- Unusual Noises: Clicking or grinding noises often result from improper bearing adjustment or debris within the hub. Disassemble, clean, and properly adjust the hub to resolve these issues.
Customization and Optimization for Better Performance
Enhancing the HB-5700 hub can lead to improved riding experiences.
- Bearing Upgrade: Consider upgrading to higher-quality or ceramic bearings to reduce rolling resistance and enhance durability.
- Sealing Enhancement: Improving the hub’s seals can provide better protection against moisture and debris, extending maintenance intervals and component lifespan.
- Lubrication Selection: Using premium, application-specific greases can optimize performance under various riding conditions.
Comparison with Similar Models
Understanding differences aids in informed decision-making.
- HB-5700 vs. HB-5800 [paid link]: The HB-5800 [paid link], also part of the 105 series, offers slight improvements in sealing and weight reduction. However, both models share similar maintenance procedures and performance characteristics.
- HB-5700 vs. Ultegra HB-6800 [paid link]: The Ultegra HB-6800 [paid link] hub provides enhanced sealing and smoother bearings, reflecting its positioning in a higher component tier. Cyclists seeking superior performance may prefer the HB-6800 [paid link], while the HB-5700 remains a cost-effective, reliable choice.
Understanding Compatibility with Other Drivetrain Components
Ensuring compatibility prevents mechanical issues and enhances performance.
- Wheel Compatibility: The HB-5700 is designed for standard road bike wheelsets with quick-release skewers and is compatible with most rim brake systems.
- Fork Compatibility: Ensure the fork dropouts match the hub’s axle dimensions (typically 9 mm for quick-release systems) and that the spacing aligns with standard road bike specifications.
- Brake Compatibility: The HB-5700 is intended for use with rim brakes. Ensure the brake calipers are compatible with the wheel size and rim width.
Conclusion
Mastering the installation, adjustment, and maintenance of the Shimano HB-5700 hub is essential for achieving optimal performance and extending the lifespan of your wheelset. Regular maintenance, proper adjustments, and understanding compatibility are key components of effective hub management.
