Brake and Derailleur Cables Bullet-proof Kevlar mesh renders our compressionless Flak Jacket cable housing lighter, more flexible and impervious to thrashing. Ultralow-friction stainless steel cables make for smooth, effortless control. And the Shield-Lock liner slip over the Shield-Lock ferrules to seal the entire system from mud, grit and grime. Consumer note: Flak Jacket brake cable systems are not disc brake compatible unless they specifically say"Disc Brake Compatible" on the packaging.

Hint: if your packaging is green and black, your Flak Jackets are disc AND rim brake compatible.
