Keep the packing the bike shipped to the dealer, it came in a box, then, after-all.
that included disc protection.

Avid BB7 on my Pocket Llama, front disc brakes aggressively, FWIW,
even with regular, ( taken off the bulk roll by BF,when they built it up ), housing.

pricier housing is a rebuild consideration, but it does not seem important, right now.


My Euro - trekking bike, a Koga Miyata WTR, came fitted with
Magura's HS[hydrostop]33, a hydraulic rim brake.
installs like a V brake, but best modulation on the planet.

Brake pads replace by unsnapping one and snapping in the new ones.

hydraulic fluid, mineral oil, is in a closed system, since braking does not heat the fluid.

once set up maintenance is just replacing pads.
there is a hand lever adjustment for pad wear..

but .. still. no Drop bar lever, I Run trekking bars , so no issue there.
