Product Information
Full details
This guide is for cyclists using SRAM rear derailleur systems looking for a durable and efficient replacement jockey wheel. The BBB RollerBoys offer smooth shifting and reduced friction thanks to their composite material and internal lubrication system, but their specific compatibility with pre-2011 SRAM models requires careful checking. Key features include 11-tooth sizing, a glass-fiber composite construction, integrated bushings, and an internal lubricant system.

FAQs
Are these wheels compatible with Shimano systems?
No, the BBB RollerBoys 11T jockey wheels are specifically designed for compatibility with certain SRAM rear derailleur systems, primarily those manufactured before 2011.
What does the internal lubricant system do?
The internal lubricant system is designed to continuously supply lubrication to the bearing area, reducing friction, wear, and noise, and extending the life of the jockey wheel.
Do I need to add grease to these wheels?
The wheels come with an internal lubricant system. For normal use, no additional grease is typically required. However, in very harsh conditions, a small amount of bicycle-specific bearing lubricant can be applied to the exterior bearing seal if performance degrades.
How many jockey wheels are included?
This product typically includes two 11-tooth jockey wheels, one for the upper pulley and one for the lower, along with the necessary bushings for installation.
What is the material of the jockey wheels?
The jockey wheels are made from a composite material that includes a 40% glass-fiber mixture for enhanced strength and durability.
Can I use these on a SRAM derailleur made after 2011?
These specific BBB RollerBoys jockey wheels are designed for compatibility with SRAM models prior to 2011. For newer systems, you would need to check for BBB or SRAM products designed for those specific model years and technologies.
Troubleshooting
Shifting is sluggish or noisy
Ensure the correct bushing was used and the jockey wheel is securely, but not overly tightened, onto the derailleur bolt. Check for any debris around the wheel or within the derailleur cage. Verify compatibility with your specific SRAM derailleur model.
Jockey wheel does not fit
Confirm that you are using the correct included bushing for your SRAM derailleur model. Double-check the compatibility list for your derailleur's exact model and year.
Reduced performance after a short period
While the internal lubricant system is designed for longevity, extremely muddy or wet conditions might require manual re-lubrication of the bearing area. Wipe clean and apply a small amount of bicycle-specific bearing lubricant.
Pros and Cons
Pros
- Durable construction due to glass-fiber composite.
- Integrated lubrication system for reduced friction and maintenance.
- Includes necessary bushings for versatile SRAM system fitting.
- Designed for smooth and efficient shifting performance.
Cons
- Limited compatibility, primarily for SRAM systems pre-2011.
- Requires checking specific derailleur model and year for fit.
- Composite material may not offer the same extreme durability as some metal alternatives in harsh conditions.
Setup, Compatibility & Care
Compatibility Check: Before installation, verify that your SRAM rear derailleur is listed within the compatible models and manufactured before 2011. This includes specific versions of 9.0SL, 9.0, X.7, X.9, X.0, XX, Apex, Rival, Force, and RED. Refer to your derailleur's manual if unsure.
Installation:
- Remove the old jockey wheels from your rear derailleur.
- Select the appropriate bushing provided with the RollerBoys set that matches your specific SRAM derailleur model.
- Install the new BBB RollerBoys jockey wheels onto the derailleur's jockey wheel bolts, ensuring the correct orientation (upper and lower).
Care: While the wheels feature an internal lubricant system, periodic cleaning is recommended. Wipe the wheels with a clean, damp cloth to remove dirt and debris. Avoid using harsh solvents or high-pressure water directly on the bearings, as this can compromise the internal lubrication. Inspect for wear regularly.
