The CenterLine is SRAM's baseline rotor — the one you'll see spec'd on a huge chunk of the disc brake bikes coming out of the factory, and the one most riders will replace with more CenterLines when the brake track wears down. SRAM positions it as a smooth and consistent stopping option that works across road, gravel, and MTB , which is why the same rotor shows up on everything from a gravel race bike to a trail hardtail. If your pads are worn into a set of CenterLines and you're overdue for a fresh rotor, this is the direct replacement.

The Centerlock versions are offered in 160mm, 180mm, and 200mm at 1.85mm thick, while the 6-bolt versions run 140mm, 160mm, and 203mm at 1.85mm, along with 180mm, 200mm, and 220mm at 2.00mm thick. Most drop-bar disc bikes will use the 140mm or 160mm sizes — SRAM's own guidance is that most road, cyclocross, and gravel bikes will only fit 140/160mm rotors, and your frame manufacturer sets the actual minimum and maximum . Check the fork and rear triangle stickers before you jump up a size.

The one-piece stainless steel construction is what keeps the price accessible and the durability high. The braking surface is designed to run smooth, consistent, and quiet, and the edges are rounded to make wheel installs easier while meeting UCI regulations. That rounded-edge detail matters more than it sounds — it's the difference between a rotor that slides cleanly between pads on a wheel swap and one that catches and knocks the pistons out of alignment. Bolts (for 6-bolt) or a lockring (for Centerlock) come in the box, so you don't need to source hardware separately. One thing worth flagging: SRAM recommends replacing the rotor whenever you change pad compounds, because running new pads on a used rotor can create noise and hurt performance. If you're switching from organic to metallic (or the reverse), plan on fresh rotors at the same time.
