Ive have Avid juicy 5's. Easy to fix and get parts but bleeding can be a pain. Check out the new Hayes Stroker series. I have worked on hopes and find them to be fairly user friendly but expensive in the states.
i have hope mono minis and they SUCK hard serious power fade over periods of prolonged braking, like more than 5 seconds, and the modulation isnt constant. ive bled them and changed the pads but nothing will fix the spongyness in the levers and the lack of power
