How is the SR/3.0 front rotor different from the standard 220 mm front rotor?
Heavy Hitter sells two 220 mm front rotors for E Ride bikes, and the fitment lists do not overlap. This SR/3.0 version is listed for the E Ride Pro-SS 3.0, Pro-SS 4.0 and Pro-SR only. The standard Heavy Hitter 220mm Front Brake Rotor Upgrade 3mm Thick covers the E Ride Pro-S, Pro-SS and Pro-SS 2.0 along with the Sur Ron Light Bee X, Segway X160 and X260, Talaria Sting and other e-motos. Both rotors share the 3.00 mm thickness and the heat-treated 410 stainless steel.
What makes the SR/3.0 rotor resist warping?
The disc is engineered for serious braking performance without warping. Heavy Hitter thickens the critical cross sections locally and heat-treats the 410 stainless steel so the disc takes the heat and load of aggressive e-moto riding where most aftermarket rotors fail. The full 220 mm diameter is laid out for maximum pad surface area and heat dissipation, which is what gives the rotor its durability and long service life.
Do I need new rotor bolts?
No bolts ship with the rotor. The product page states that you will need to reuse your existing mounting bolts from the stock front rotor. The matching rear disc for the same three bikes is the Heavy Hitter 220mm Rear Brake Rotor Upgrade 3mm Thick SR/3.0.
Where can I get it?
The Heavy Hitter 220mm Front Brake Rotor Upgrade 3mm Thick SR/3.0 is made by Heavy Hitter and sold by GritShift.
