This kit is a single hydraulic hose with banjo fitting, olive, barb and 2 meters of hose for one Campagnolo disc brake assembly from road lever to disc caliper. The side mount banjo fitting attaches to an 11, 12, or Ekar13, shift/hydraulic disc brake lever, while the other end (once cut to length) accepts the olive and barb for attachment to the disc brake caliper.

Campagnolo requires use of their specific mineral oil brake fluid due to it's low viscosity and engineered boiling point. Two of these hose kits are required to set-up one bike- front and rear disc brakes.
