Rotor Chain Catcher for Braze-On Front Derailleurs Red Features
Shifting a chain off the big ring, past the little ring, and onto the frame is a more common occurrence thanks to modern shift systems. It’s the kind of thing that can chew your frame and end your race. Just ask Andy Schleck, the Luxembourger who lost the Yellow Jersey thanks to a dropped chain. Rotor solves the problem with their Chain Catcher. It’s 12g of insurance you don’t want to live without.
