Frequently Asked Questions

Q: What bike types is this RIDERACE ceramic derailleur pulley wheel compatible with?

A: This 11T jockey pulley wheel is designed to fit most rear derailleurs used on road bikes, mountain bikes (MTB), and gravel bikes. It accommodates 4mm, 5mm, and 6mm roller screw axles, giving it broad compatibility across popular drivetrain systems.

Q: Why choose a ceramic bearing pulley over a standard steel bearing?

A: Ceramic ball bearings outperform traditional steel bearings in low-load, high-speed environments — exactly the conditions found in a bicycle drivetrain. They generate less friction, spin more smoothly, resist corrosion better, and typically last longer, helping your chain run efficiently ride after ride.

Q: Is the AL7075 aluminum alloy significantly lighter or stronger than regular aluminum?

A: Yes — AL7075 is a high-performance aerospace-grade aluminum alloy that offers a superior strength-to-weight ratio compared to common aluminum grades like AL6061. This means the pulley wheel is both notably light and highly resistant to the mechanical stress of regular cycling use.

Q: How do I know which bolt size (4mm, 5mm, or 6mm) I need?

A: Check your existing rear derailleur's jockey pulley mounting bolt diameter. Most manufacturers specify this in the derailleur's manual or product page. The RIDERACE pulley wheel supports all three common sizes (4mm, 5mm, 6mm), so it covers the majority of rear derailleurs currently available on the market.
