The Centreline rotor represents all that SRAM and Avid have learned through many years of designing braking systems.

These rotors are optimised to create a consistent feel. The braking surface area stays consistent regardless of position on the rotor. This design minimised the chance of vibration.

The large cut outs ensure good ventilation and aid in keeping the rotor cool. The stainless steel material used is extremely robust.

These will suit all AVID or SRAM brakes - plus most other brands.

Weight for a 160g rotor is 112g.

The "square edges" or "rounded edges" refers to the outer edges of the rotor. The newer version has the edges rounded to make them easier to line up during wheel changes and less likely to cut in crashes.
