Frequently Asked Questions

Q: What type of bearing does this 11T derailleur pulley wheel use?

A: This derailleur pulley wheel uses a ceramic bearing, which offers a lower friction coefficient and greater wear resistance than standard steel bearings. This means quieter operation, smoother gear changes, and a longer-lasting pulley for your road bike drivetrain.

Q: Is the 11T ceramic bearing pulley wheel compatible with my road bike derailleur?

A: This 11T pulley wheel is designed for compatibility with a wide range of road bike rear derailleurs, functioning as both a guide roller and idler pulley. We recommend verifying your specific derailleur model's bolt spacing and pulley tooth count before purchasing to ensure a perfect fit.

Q: What makes AL7075 aluminum a good choice for a derailleur pulley?

A: AL7075 is an aircraft-grade aluminum alloy known for its outstanding strength-to-weight ratio. Using it in this derailleur pulley wheel keeps rotational mass low — which can improve drivetrain efficiency — while still delivering the durability needed to handle the demands of road cycling.

Q: How do I install this derailleur pulley wheel on my bike?

A: Installation is straightforward. Remove the rear derailleur cage bolt, slide out the old pulley, place the new ceramic bearing pulley wheel in position, and re-insert the bolt. Always ensure the pulley spins freely and the chain is correctly threaded before riding. If you're unsure, consult a professional bike mechanic.
