I just picked up a pair of V-brake pads (rim brakes) at the LBS. They are made by Tektro. The pads are way thicker than the ones i took off. Therefore i had to set my brake arms out wider to clear rims. I went for a quick test ride and it seemed like i didn't have that much stopping power.
The pads are aligned properly according to Park. I just wonder if having the arms farther apart results in less leverage?
