Brake Disc Specificaitons

Hi there,


I am interested in getting the brake rotors, especially the smallest 120mm #BRK-500. Does anyone know the technical specification of the 120mm brake rotor, such as the mounting hole diameter, thickness, weight, etc? I can't seem to find the information anywhere. Thanks in advance!

Here are the dimensions and weight of BRK-500:

  • 3.2mm Thick
  • 120mm OD
  • 26mm ID
  • 5.5mm ID Mounting Holes
  • 31.6mm Adjacent Mounting Hole Distance (Center To Center)
  • 36.5mm Bolt Hole Circle (BCD)
  • Weight 0.55 Pounds
