Narrow Disc Brake Calipers (F180/R160)

For Front 180mm or Rear 160mm Rotors 14mm Thickness from Disc Surface to Inside Mechanical Only If you're having trouble fitting your Direct Drive motor around your disc calipers, this is the answer. Description ProMax Mechanical Disc Brake Caliper F180mm/R160 This disc brake caliper is unique because it has a thin profile head to fit the spacing between the hub motor side cover and the disc rotor. The spacing requirement is 18mm and your existing caliper or a few other high-end caliper heads may fit, but if they do not fit the 18mm spacing, this is the caliper you'll need for your mechanical disc brakes to work with an E-BikeKit hub motor. Watch the video to see the spacing limitation and why this caliper may be the perfect solution for your e-bike conversion.
