Why does the rear rotor run 3 mm thick?
Most aftermarket rotors fail under the heat and load of aggressive e-moto riding, so Heavy Hitter built this rear disc to deliver serious braking performance without warping. It is 3.00 mm thick with localized thickening in its critical cross sections, and the 410 stainless steel is heat-treated for enhanced durability and a long service life. The 220 mm diameter is designed for maximum pad surface area and heat dissipation.
Will a 220 mm rotor fit my rear caliper?
Two checks before ordering. This is a 3 mm thick rotor, so confirm that your caliper is compatible with a 3 mm disc. And if your bike came stock with a 203 mm rotor, you may need 220 mm caliper spacers to run the larger diameter. No mounting hardware is included with the rotor.
Which 220 mm rotor goes with it?
The front-wheel counterpart is the Heavy Hitter 220mm Front Brake Rotor Upgrade 3mm Thick, which carries its own fitment list. This rear rotor's E Ride fitment stops at the Pro-S, Pro-SS and Pro-SS 2.0; the Pro-SS 3.0, Pro-SS 4.0 and Pro-SR take the separate 220mm Rear Brake Rotor Upgrade 3mm Thick SR/3.0.
Where can I get it?
The Heavy Hitter 220mm Rear Brake Rotor Upgrade 3mm Thick is made by Heavy Hitter and sold by GritShift.
