The Center of it All.

The SRAM CenterLine X Rounded Rotor in Centerlock takes the amazingly quiet, smooth, and exceptional cooling capacity of the Centerline and subs in an aluminum carrier to drop grams, further improve cooling, and stiffen the rotor. These particular rotors feature a rounded edge past the braking surface making them safer in mass start events and comply with the UCI's requirements for rotors used in road racing.

The Centerline gets its name from the strategically placed vents on the braking surface that help reduce overheating and reduces noise. Better heat management improves performance and lever feel with repeated braking on long descents. Centerline X Rotors feature the same braking surface as the 1-piece CenterLine, however the addition of the aluminum carrier drops weight and stiffens the rotor to improve performance. Dual materials, with different rates of thermal expansion and contraction, help prevent the rotor from warping under heavy use. SRAM chamfers removes the 90-degree corner off the edge of the rotor making it safer for everyone.

  • Dual material rotor blends light weight and durability
  • Vent hole design in brake surface promotes cooling
  • Rounded edge improves safety
  • Lockrings not included
  • Steel braking surface for durability and aluminum center piece to save weight

Light & Powerful

    Sram did a nice job with these rotors. The stopping power is top notch. I am using them for my Specialized Tarmac Disc that I have eTap with. They work great paired together.

    Light with excellent stopping power

      The SRAM Centerline X Rounded Rotors are lightweight and dissipate heat effectively to ensure maximum sustained stopping power.

      A Step Above

      • Familiarity: I've put it through the wringer

      These rotors are a step above the standard Centerline rotors. The aluminum carrier helps drop some weight, as well as add some style to the rotor, although it will never look as sexy as Shimano's Icetech rotors. They've held up well against abuse and seem to shed heat pretty well also.

      Where do I get the lockrings to hold the rotor in place when I'm using thru axle


      This would be the lockring I would suggest for these rotors:

      All the braking power ...

      • Familiarity: I've used it several times

      ... but less of the slice & dice alleged to be attributable to disc brakes. The rounded edges will make them safer, and still the best rotors to pair with SRAM’s hydraulic disc brake calipers.
