cable discs are fine, great even.
if someone wants to buy me a new bike, with Shimano 105, and Hydraulic disc brakes, then i won’t complain.
But with my own money, i’m more than happy with Shimano 317’s – and my old sora sti levers.
they need a little bit of attention, but it amounts to nothing more than adjusting the static pad every couple of rides. it takes about a minute. certainly less time than oiling a chain, or checking tyre pressures, etc.
i did have trp spyres, but i found them a little too … flexy, i like my brakes a bit more ‘wooden’.
(i sold the spyres to a friend, he’s very happy with them)
i did have bb5’s, and they were good too.
