SRAM CenterLine X Rotor - Centerlock

Confident lines.

When you're screaming down a technical, never-ending descent, it's always beneficial to have SRAM's CenterLine X Rotor - Centerlock along for the ride. It takes the prized cooling capacity and high-powered braking functionality from SRAM's venerable Centerline and trades the steel center for a light and durable aluminum center piece to lost a few grams in the process.

Strategic vents across the steel braking surface provide exceptional heat management to reduce overheating, which means better consistency for confident speed modulation through technical and steep terrain. The 12-spoke design also resists warping and lateral bending for smooth, stable braking every time you need it.

I'm sold.

  • Familiarity: I've used it several times

This past December, I purchased a Santa Cruz Stigmata CC with an Ultegra hydraulic disc drivetrain, and wanted to get a second pair of wheels for use with skinny tires on the road. At the time I bought the wheels, we were out of stock of the Shimano XTR/RT99 rotors that came on the stock build, so I grabbed a pair of these instead. Thus far, I cannot tell any difference between the two, except that these cost me less money than the RT99s would have. Same stopping power, same general lack of noise, and as near as my fingers can tell, same heat dissipation.

Needed centerlock with wheel upgrade

I have these brake rotors on another set of wheels that are six bolt mounted. I needed these centerlock discs for my new wheels. Both mounting versions are the same fit and performance with an exception being, no brake noise with the centerlock. Braking performance is very good with Sram's Level TLM calipers.

Stops good, minimal squealing.

I'm running these rotors instead of Shimano rotors on another set of wheels for my Stigmata. Have not noticed any difference in braking power or heat dissipation between the two, and these are less expensive. I've got no problem recommending SRAM rotors instead of Shimano rotors, even with Shimano disc brakes.

Minimal squealing with properly adjusted calipers and brake pads burned in.

Unanswered Question

Which lockring would work with these discs?
Brand/Part number would be great.


Work great

No brake squeal, aluminum carrier for better heat dissipation, plus they look cool. What's not to love?

Are these rotors compatible with Force CX1 brakes?

Hey Alan! As long as you have a centerlock hub, these should do the trick.

140's are just fine in my book

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

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

is the lock ring included?
Do you know the weight of the 160 mm (or any of the rotors)?

No lock ring included. I just received and weighed 2 160mm centerlock rotors - 120g and 121g. (Yeah I know this answer is about a year too late)

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.
