CenterLine X Rounded Rotor

The SRAM CenterLine X Rounded Rotor brings all the high-powered braking and effortless cooling capacity of the original CenterLine rotor and fuses it with a dual-material construction that pairs its steel braking surface with a lightweight and long-lasting aluminum centerpiece. Its 12-spoke design prevents lateral bending and warping under heat stress for confident stability and smooth, predictable braking. As with it single-piece counterpart, this rotor boasts venting lines across the braking track to minimize overheating and provide consistent power on wide-open descents and highly technical runs.

Couldn’t be trued

I've used it several times

Don’t do it. Yes they are light, but they warp as soon as they get hot and will rub and squeak endlessly. Put on generic sram rotors (maybe 40 grams heavier) and they work great.

Please package better for shipping.

I've put it through the wringer

The rotors are great however Backcountry/Competitive you really need to put these in a box to ship not an unpadded envelope. I'm almost afraid to install these for fear they were warped while being abused in transit and am considering returning them. You can do better.

might be a material handling issue

I've used it once or twice and have initial impressions

backcountry may need to look at the material handling process for items like brake rotors. Rotor was bent more than the one I was replacing. Leaving on a trip, so I had to use it. Not a huge deal as I was able to get it reasonably straight with a few bends. Just shouldn't need to make that effort when you spend full retail on a new brake rotor.
