Control cable quality.

The ease of and improving clutch action and front brake effectiveness is often mentioned on here with comments on the importance of fitting good quality cables.
Whilst faffing about tidying up the shed I came across a dozen or more cables that I'd bought whilst experimenting with a combined brake/clutch adaptation for my Matchless. I was struck by the difference in quality between the conduits (the spirally wound outers) of the cables from autojumbles (5.2mm dia.) and the more expensive and robust ones (7.1mm dia.) from in this case, Venhill Cables and which may be of interest to others. The inners are similar but the outers and the end ferrules on the Venhill cables are far more substantial.
The outers of the less tightly wound and cheaper cables tend to compress throughout the whole length of the cable giving a spongy feel to the front brake action and in the process of compression friction is generated on the inner, especially at bends. Note how the flimsy ferrule on the little used cable below has already begun to compress/crush the outer due to the spiral outer compressing.....O.K. for a light throttle cable but not robust enough for a front brake.
