Reaction is a high-octane cable system optimized for today's brake and drivetrain systems. The special housing delivers excellent compressionless performance for enhance cable response, especially for brakes, which has been difficult for other makers to produce.
Cables have smaller cable ends needed for Campy. Housing and cable lengths are designed for conventional road bike and may not have enough length for some disc brake road bikes.
We recommend extra high quality cable cutters or a Dremel tool to trim these RapidWire housing. They are a bit more tougher and stiffer than conventional cable housing.
