Durable construction suitable for frequent workshop use
Summarized by Shop
A disc rotor wears thinner over service life. The brake pad slowly removes metal at the wear track, and the rotor crosses its manufacturer-published minimum thickness somewhere between two and four years of regular use (depending on rider weight, terrain, pad compound, and how much the brakes get dragged). Past that minimum, the rotor is
