All my road bikes and mtn bikes are Shimano hydraulic.
I wrench on all my bikes.
Have owned cable disks before.
I would never go back to cable.
Hydraulic is very easy to maintain. They just work so darn good.
Quite maintenance free really.
Highly suggest thru axle too. Everything always lines up perfect so no rub. Love it. It is the other piece of the puzzle that makes disks so nice to live with.
