Hi, I have a C3 Heartbeat. I used red yoyofactory response pads, 19mm. Now I don’t have anymore so I wanted to order new one. But now I’m a little confused because there is only “thin” and “wide” avaiable. Just to be sure. The “thin” pads are the normal ones?

Yes, thin pads refer to the 19mm OD pads, broad or wide pads usually refer to 21mm OD pads. Od means outer diameter.
