They're like the TRP closed hydraulic system with cable actuation. There are a number of advantages to it and the Hy/rds were the best brakes I've used other than full hydraulic. I expect the Juins will perform similarly and I've read good things about them.I'm sure they are but a bit pricey though. I appreciate that you get what you pay for but there are limits. Are they full hydraulic or some sort of hybrid combination like the TRP HyRd?
