🔧 Why This Rear Derailleur Is So Good
The RD-7900 was Shimano’s premier 10-speed road derailleur, offering crisp, race-level shifting with a lightweight design. Built with a carbon composite outer cage and alloy body, it delivers precise gear changes and excellent chain tension for competitive riding. The short cage version is optimized for double cranksets and standard road cassettes.
