anonymousCompared to the many one-piece rotors I've had, these are at least are light, and so far, seem to stay truer. Probably because the aluminum center area plus the added heatsink is more rigid than the single-piece steel versions. Also, unlike an Avid set I bought, these came with a proper XT Centerlock lock nut! Oh yeah... They stop the bike smoothly and quietly.
