I have several bikes with disc brakes operated by cables, but with good-quality rims. For the type of riding that I do, and am likely to continue, the disc brakes don't offer me any significant advantage in my judgment with one exception -- the tandem when ridden in really long and deep downhills with corners... and even then I would be uncertain as to the required ongoing performance potential. I am in the process of acquiring rear wheel disc brake assembly, but the project of not completed yet in planning.
