If it's time to replace your worn, warped or bent rotors, these high-strength, low-carbon steel rotors might be the way to go because they offer a longer life and better braking than most OEM rotors. For corrosion resistance, they are plated with yellow zinc. Furthermore, they have been CNC-laser cut and precision ground to produce a flat, distortion-free profile, and they will reduce rotating mass. If you ride in mud, you'll find the undrilled version can provide longer pad life. The retail price is $89.95.
