FAQs
What is the primary purpose of Shimano Dura-Ace Grease?
Its primary purpose is to lubricate and protect high-quality Shimano bearings, ensuring smooth operation, preventing rust and corrosion, and extending component life.
Can I use this grease on non-Shimano components?
Yes, it can be used on other bicycle components, especially those requiring high-performance lubrication. However, it is specifically formulated and tested to meet Shimano's standards for their premium parts.
How often should I reapply this grease?
Reapplication frequency depends on riding conditions. For general use, consider servicing every 6-12 months or after significant exposure to water or dirt. For competitive or extreme conditions, more frequent servicing may be beneficial.
Is this grease suitable for mountain biking?
Yes, its water-resistant and protective properties make it highly suitable for the harsh conditions often encountered in mountain biking, particularly for hubs and bottom brackets.
What does 'same specification used as standard' mean?
It means this grease is manufactured to the exact same quality and performance standards that Shimano uses when assembling their new Dura-Ace components in the factory.
How much grease should I use?
Apply a thin, even layer to the bearing surfaces. Over-greasing can attract dirt and impede smooth rotation. The goal is to coat the rolling elements and races without excessive buildup.
Troubleshooting
Grease feels too thick or stiff in cold weather.
This is normal for specialized greases. Allow the component to warm up slightly before riding, or consider a slightly lighter grease for extremely cold climates if performance is significantly impacted.
Water contamination is suspected in bearings.
Disassemble the component, thoroughly clean the bearings and races, dry completely, and reapply fresh Shimano Dura-Ace Grease.
Component feels gritty after greasing.
The component may not have been cleaned sufficiently before application, or contaminants may have entered during reassembly. Disassemble, clean all parts meticulously, and reapply grease.
Pros and Cons
Pros
- Ensures optimal performance for high-end Shimano bearings.
- Provides excellent protection against environmental damage.
- Contributes to a longer service life for critical components.
- Formulated with the same standards as original equipment.
Cons
- May be more expensive than general-purpose greases.
- Primarily intended for high-performance applications.
- Small container size (50g) may require frequent repurchase for heavy use.
Setup, Compatibility & Care Instructions
Setup:
- Clean existing grease and contaminants thoroughly from the component's bearing surfaces using a suitable degreaser.
- Apply a thin, even layer of Shimano Dura-Ace Grease to the bearing balls and races using a small brush or gloved finger.
- Reassemble the component, ensuring not to overtighten, allowing the grease to distribute naturally as parts move.
Compatibility:
- Primarily designed for Shimano Dura-Ace and other high-end Shimano bearing applications (e.g., hubs, bottom brackets, pedals).
- Can be used on other high-quality bicycle components requiring premium grease, though its specific formulation is optimized for Shimano standards.
Care:
- Store the grease in its original container in a cool, dry place away from direct sunlight.
- Ensure the container lid is tightly sealed after each use to prevent contamination and drying out.
- Regularly inspect serviced components for signs of grease degradation or contamination, and reapply as needed based on riding conditions and mileage.
