An updated Taper Bore design in the Avid Elixir 9 Carbon 2012 Disc Brake Set (OE) incorporates a new air-trap feature, resulting in ridiculously smooth control you can count on. Combining a two-piece caliper & HS1 cross-drilled rotors makes the Elixir 9 simultaneously smooth & powerful. The introduction of tool-free reach & contact adjust turns these production brakes into your brakes, letting you dial in the perfect feel in under a minute.
