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

Unanswered Question

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

Avg. ride time: 3m per week

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.
