The SRAM CenterLine X is a full stainless steel disc brake rotor with a rounded petal design that channels water and debris away from the braking track. The rounded outer edge reduces the risk of catching on soft surfaces or clothing. A consistent braking surface and high thermal mass make the CenterLine X a solid choice for trail and gravel riding.

Highlights

  • Full stainless steel construction for consistent pad bite and durability
  • Rounded petal design — sheds water and debris, safer outer edge
  • Available in 6-bolt and Centerlock mount versions
  • Multiple diameter options
  • Compatible with SRAM and Shimano hydraulic disc brakes

Stainless construction

Full stainless steel rotors run slightly heavier than two-piece designs but offer more consistent braking in varied conditions — the single-material construction handles heat more uniformly and wears more predictably. For riders who prioritise braking feel over marginal weight savings, the CenterLine X is the straightforward choice.

Fit and compatibility

Available in 6-bolt and Centerlock mount versions. Compatible with SRAM and Shimano hydraulic disc brakes and standard IS/post-mount caliper adapters. Confirm rotor diameter and mount type for your wheel and caliper before ordering.
