My front brake: BB7 caliper, 180mm rotor, slic cable well lubed, SD7 lever. Perfect. I was origianly just using this brake while i save up for a hydraulic but no need to BB7 is the best cable pull disc brake ive ever used, when set up square and true with a good quality cable and lever its just a really light pull and bang instant lock and bite with good hold too! Reccommended!
