SRAM CenterLine 2-Piece 6-Bolt Rounded Edge

SRAM's CenterLine 2-piece 6-bolt disc brake rotors with rounded edges, which is good news for road disc brake users who have great 6-bolt hub wheels and want more options. In an effort to improve safety and mollify the pro road peloton, the UCI has mandated that road disc brake rotors have rounded edges along the outer circumference. That adaptation and the alloy spider are the only real differences between the rounded and standard CenterLine disc brake rotors from SRAM, whose CenterLine rotors represented a significant improvement in terms of increased performance and greatly reduced braking noise.

Engineers at SRAM figured out a way to keep the center of friction consistent though the entire rotation which minimizes vibration. What the means to you is Centerline rotors stop more quickly with less effort. The other main benefit is that cyclists around you will appreciate is super quiet braking.

The 6-bolt mounting system has dominated the mountain bike world, but many road disc wheelsets featured the splined CenterLock format. Now we are seeing more road, gravel and cross wheels with 6-bolt, and many 6-bolt rotors can be used with an adapter on CenterLock hubs. Actual braking performance comes from the braking surface however, and the CenterLine features stainless steel construction. The rounded edge rotor is machined from a single piece of material with precise balance and design. The rotor is then mounted to a lighter weight aluminum spider with the 6-bolt interface, which also reduces heat transfer to the hub itself. Ultimately, the CenterLine 2-Piece 6-Bolt Rounded Brake Rotor carries heat away quickly to sustain braking power without fade or overheating. Designed for best use with road, cyclocross, and XC MTB.
