Frequently Asked Questions

Q: What bike types is this jockey wheel compatible with?

A: This metal derailleur jockey wheel is designed for universal compatibility and fits most MTB (mountain bike) and road bike rear derailleurs. It works with axle bolt sizes of 4mm, 5mm, and 6mm, making it suitable for a wide range of drivetrain setups.

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

A: The "T" refers to the number of teeth on the pulley wheel. An 11T (11-tooth) jockey wheel is more compact and is typically used as the upper guide pulley on a rear derailleur, while a 13T (13-tooth) is slightly larger and often used as the lower tension pulley. Check your derailleur's specifications to select the correct size for your setup.

Q: How do I install this rear derailleur pulley?

A: Installation is straightforward. Simply remove the existing worn jockey wheel from your rear derailleur using the appropriate bolt (4mm, 5mm, or 6mm), align the new metal pulley in place, and secure the bolt firmly. No specialist tools are required beyond a basic hex/Allen key.

Q: Is this jockey wheel suitable for all chain speeds (e.g. 7-speed, 9-speed, 11-speed)?

A: This pulley is designed for broad compatibility across common drivetrain speeds. We recommend checking the tooth count and diameter against your current derailleur specifications to ensure the best fit for your specific gear system before purchasing.
