The 2-piece Shimano SM-RT30 Disc Rotor features a Centerlock mount and is completely made of stainless steel. The rotor is only compatible to Resin brake pads.
For an easier installation the included lockring features an internal and external serration.
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring.
The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation.
In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
