jagwire cables not compatible with 105 caliper?

fitted new 105 calipers today but the metal casing over the outer brake cables will not slot into the adjuster on the calipers. when I apply the brakes there is a juddering feeling. do I have to buy shimano cables to fit?

    I'm pretty certain that 105 are not meant to have the metal ferrule going into the adjuster on the callipers - the cable outer should just slot in by itself.

    Take a look at this - it should explain it better than me: http://mpora.com/videos/AAdp2azv3tmg

    That's right you have to carefully remove the metal ferrule. I fitted 105's to my bike and that's the only way to get the outer cable slotted in properly.

    If there's no metal/plastic (rigid) ferrule on the end of the outer, what stops it deforming when the brakes are applied and thus loseing braking efficiency?

    the caliper itself has a metal ferrule of sorts which is part of the adjuster

    The supporting structure in the brake cable housing is a short pitch wound spiral, so it doesn't tend to open up under braking. There would need to be a tensile load on the cable housing to cause it to do that.
