Why Upgrade Your Jockey Wheels?

Stock jockey wheels wear down over time, leading to sluggish shifts and chain noise. The ENLEE bearing pulley wheels feature sealed bearings that spin freely with minimal resistance, keeping your drivetrain efficient and quiet. The CNC-machined alloy construction also adds a premium look to your rear derailleur cage while saving grams over heavier OEM plastic variants.

Frequently Asked Questions

Q: Are these ENLEE jockey wheels compatible with all Shimano derailleurs?

A: The ENLEE 11T and 13T bearing pulley jockey wheels are designed to be compatible with a wide range of Shimano rear derailleurs for both road bikes and MTBs. The bolts are available in 4mm, 5mm, and 6mm diameters to cover most common Shimano derailleur models. Please check your derailleur's specifications for the correct tooth count and bolt diameter before ordering.

Q: What is the difference between the 11T and 13T jockey wheel sizes?

A: The tooth count (11T vs 13T) refers to the number of teeth on the pulley. The 13T pulley is slightly larger (50×5mm, 14g) and is typically used as the guide/upper pulley on certain derailleur models for improved chain wrap, while the 11T (43×5mm, 12g) is commonly used as the tension/lower pulley. Always verify which size your specific derailleur requires before purchasing.

Q: What colors are available for the ENLEE CNC jockey wheels?

A: The ENLEE rear derailleur jockey wheels are available in five anodized color options: Black, Red, Blue, Gold, and Colorful (rainbow anodized). This allows you to match or contrast with your existing drivetrain and frame aesthetics.

Q: How do I install the ENLEE bearing pulley jockey wheels?

A: Installation is straightforward — simply remove the bolt securing your existing jockey wheel on the rear derailleur cage, swap in the ENLEE pulley, and fasten securely with the appropriate bolt size (4mm, 5mm, or 6mm). We recommend applying a small amount of lubricant to the bolt threads for smooth installation.
