ENLEE Ceramic Bearing Aluminum Alloy Rear Derailleur Jockey Wheel – MTB & Road Cycling

Upgrade your drivetrain with the ENLEE AL25 Ceramic Bearing Jockey Wheel — a high-performance rear derailleur pulley engineered for smooth, efficient chain guidance on mountain bikes and road bikes alike. Built from high-strength aluminum alloy with a CNC-hollowed body, this jockey wheel delivers ultra-low friction rotation, improved transmission efficiency, and a satisfying weight saving over stock plastic pulleys.

Key Features

• Ceramic Bearings: Ultra-smooth, low-friction rotation for silky shifting and more energy-efficient pedaling every ride.
• High-Strength Aluminum Alloy Body: CNC-machined and hollow-forged for maximum strength with minimal weight — impact-resistant and evenly stressed for consistent performance.
• Anodized Surface Finish: Electroplated anodizing protects the alloy body against rust and oxidation for long-lasting durability.
• CNC Hollow Design: Optimized tooth profile promotes fast, clean chain engagement and reduces wear over time.
• Multiple Tooth Sizes: Available in 10T, 12T, 14T, and 16T to suit a wide range of derailleur setups and gear configurations.
• Six Vibrant Colors: Choose from Black, Purple, Blue, Red, Pink, or Orange to personalize your build.
• Model AL25: Compatible with standard rear derailleur cages on MTB, gravel, and road bikes.

Why Upgrade to Ceramic Bearing Jockey Wheels?

Standard plastic or steel-bearing pulleys create friction that robs you of watts and accelerates chain wear. ENLEE's ceramic bearings have a harder, smoother surface than steel, meaning less rolling resistance, longer bearing life, and more consistent shifts — whether you're grinding up a technical trail or hammering a fast road descent.

Frequently Asked Questions

Q: What tooth count should I choose for my rear derailleur jockey wheel?

A: The correct tooth count depends on your derailleur cage and desired chain wrap. Most standard rear derailleurs use a 10T or 11T pulley. Upgrading to a larger 12T, 14T, or 16T jockey wheel increases chain wrap angle around the cassette, which can improve drivetrain efficiency. Always check your derailleur cage clearance before selecting a larger tooth size.

Q: Are ENLEE ceramic bearing jockey wheels compatible with Shimano and SRAM derailleurs?

A: The ENLEE AL25 jockey wheel uses a standard bolt-on design compatible with most common rear derailleur cages, including popular Shimano and SRAM systems. We recommend verifying your derailleur's pulley bolt spacing and cage clearance against the listed dimensions to confirm a direct fit before ordering.

Q: How do I maintain ceramic bearing jockey wheels?

A: Ceramic bearings require minimal maintenance compared to steel bearings. Periodically wipe the pulley clean of mud and chain lube buildup, and apply a small amount of light bicycle-grade lubricant to the bearing seat if needed. The anodized aluminum body resists rust and oxidation, keeping the wheel looking and performing great for extended periods.
