I have three bikes with hydro discs, and they are all excellent maintenance free brakes, if that helps. The Novelas were fiddly and needy when they worked, and then they failed altogether when the bearings wore through and skipped out of their ramp races. It seemed to me that the bearing/ramp mechanism, at least in the Novelas, was fundamentally flawed.
How many and which cable brake systems have you owned? And that's not a smart-ass question.
I see your point. I thought I'd qualified my initial remarks sufficiently, but I realised after I'd posted that I hadn't.
