RE Disc or Drum brakes
If you weigh the Hub,Rotor & caliper of a disc brake system and compare it to the weight of the drum brake system they work out almost equal.
Discs "can" give better braking in the dry! but will go through brake pads rapidly.
Sometimes they will need adjusting after a long/steep descent.
Also rotors wear and need renewing and they're prone to warping causing the brakes to rub making a horrible annoying noise!
Compared that to drums that give consistent braking in all conditions and last a very long, long time 50,000 miles+ , don't make any noise and are practically maintenance free And when adjusted properly don't bind.
DIscuss anything relating to non-standard cycles and their equipment.
