Take the best line.

The SRAM Centerline X Rotor takes all the amazing cooling capacity and high-powered braking functionality of its predecessor, the Centerline, and swaps out the old steel center for aluminum to drop a few grams along the way.

The Centerline X gets it name from a line of strategically placed vents running through its steel braking surface that reduce overheating. Better heat management improves braking consistency on long descents and other brake-heavy trail sections compared to rotors without these vents. The Centerline X Rotor also features the same 12-spoke design as its predecessor to reduce lateral bending or warping under heat stress for stable, smooth braking every time you pull the lever.

  • Dual material rotor blends light weight and durability
  • Steel braking surface and aluminum center piece
  • Venting lines in brake surface promote cooling
  • 12-spoke design resists warping
  • Lockrings not included

140's are just fine in my book

  • Familiarity: I've used it several times

Building up a new bike and chose SRAM 140mm rotors because of the lack of availability of Shimano 140mm rotors.....don't need 160mm or the hassle of obtaining a flat mount adapter.

Stopping Power

  • Familiarity: I've put it through the wringer

Rotors...a necessary item. Work great with my Sram Guide brakes and add some weight savings when every little bit counts.

Double question - 1) These are the latest version Guide Rotors, yes?
2) Can I use these with my XT brakes?

Hey Chris,

It is a double yes on this one. Let me know if you have any other questions. These rotors are for centerlock hubs as well.


Looks awesome, performs even better.

High performance braking surface, in an efficient lightweight package. The Centerline X rotor will be sure to stop you, as well as stop others to admire the race-like appearance and design.

Save weight where you can

  • Familiarity: I've used it several times

Brakes just slow you down, so they might as well be as light as possible without sacrificing power. These Centerline X rotors do just that, same brake surface as the 6 bolt, just a lighter carrier.
