A: Yes. The ENLEE 11T and 13T jockey wheels are designed for universal compatibility with most standard rear derailleurs on mountain bikes (MTB), road bikes, and hybrids. Always verify the tooth count and bore size match your specific derailleur model before installing.

A: Replacing a derailleur pulley is a straightforward repair that most cyclists can do at home with basic tools.
