Ok folks, I'm confused and in need of advice. On my commuter (touring) bike, I just upgraded my BB5's to BB7's. In the process, decided/realized that I also need to replace my cables and housing (@mikes was right in his answer to a past question of mine).
In surfing the 'net I see that I can get compressionless cable housing or "regular" cable housing. Compressionless seems to be preferred by folks interested in higher levels of performance.
That said, I have always trusted Sheldon Brown's advice on a variety of bike related topics. He seems to say that compressionless housing is made for (and should only be used for) indexed shifters and it might be dangerous to use it for brakes. However, there are several vendors (1),(2) who sell compressionless housing made specifically for brakes.
So, is Sheldon wrong? Will I be introducing additional risk in my braking system by using them? Will compressionless cable housings make a significant difference in the performance of my mechanical disc brakes?
