Full assembly of a downhill bike disc brake with a floating rotor. The design allows for a proper distribution of heat during hard and extensive braking without distortion of the rotor which is common with commercial designs. A smaller (185mm) rotor is also possible to use with the same central mount.
Comments:
We used standard bolts and nuts for cranks. The "spider" in the center was made for test from Aluminium 6061, later a mold was made and a carbon-kevlar mixture composite version was made. The rotor can be made of any adequate chrome stainless steel, and depending on hardness you should choose the brake pad type. for softer SS, use composite (carbon) pads as shown on the images.
Thanks!
You will most likely need to cut from the bolts and nuts, the regular ones are designed to hold approximately 5-6mm of material together, you need 2.10-2.20mm gap between the nut and bolt cap.
