Road Disc Brake Rotor Sizing: 140mm vs. 160mm Thermal Dissipation & Brake Fade

Front 160mm disc rotors deliver 30% greater thermal dissipation area over 140mm rotors.

Lowering rotor operating temperatures by 60°C prevents hydraulic mineral oil boiling and resin pad glazed brake fade on alpine descents.

Section IV: Ice-Technologies Freeza Clad Rotor Heat Dissipation

Sandwiching an aluminum core between stainless steel braking surfaces with cooling fins lowers rotor temps by 50°C.
