Super Record 12X2 Speed rear derailleur: pure technology. Functionality combines with the highest quality materials and exceptional weight to generate unparalleled performance
Constant precision: On rough roads, the spring positioned between the upper body and the pivot absorbs the vibrations, ensuring the chain always rests properly on the sprockets
The pulley wheels on the 12-tooth derailleur cage allow the chain to move more smoothly
The initial position of the rear derailleur can be adjusted to suit any cassette
Easy wheel replacement: The rear derailleur is positioned further back, making it easier to slide the wheel out and replace it
