Hydraulic bicycle component

A hydraulic bicycle component comprising:

• a first device defining a first fluid path and having an attachment section defining internal threads therein, the first device having an inner surface that encircles a portion of the first fluid path, the inner surface of the first device having a conical shape;
• a first hydraulic hose including a tubular insert that defines an end surface, with a central passageway extending through the first hydraulic hose and the tubular insert with a central opening in the end surface of the tubular insert open to one end of the central passageway;
• a tubular member installed on the first hydraulic hose co-axially aligned with the central passageway, the tubular member defining external threads thereon;
• a first seal directly fixed to the end surface of the tubular insert covering the end surface and the central opening of the central passageway, the central passageway further defining a central axis, the end surface being perpendicular to the central axis;
• and
• a first seal rupturing structure having a tubular end section, an annular flange section and a tubular body section, the tubular body section being disposed in a fixed position within the first fluid path of the first device, with a first surface of the annular flange section having a conical shape that contacts and mates with the conical shape of the inner surface of the first device;
• the first device and the first hydraulic hose being configured to attach o one another via the external threads and the internal threads, such that
• in an unattached orientation prior to attachment of the first hydraulic hose and the tubular insert to the first device, the first device and the first seal rupturing structure are spaced apart in a non-contacting relationship from the tubular insert and the first seal, with the first seal sealing the end of the tubular insert, the first seal rupturing structure being fixed in the fixed position relative to the first device such that the first seal rupturing structure remains in the fixed position relative to the first device with the first device in the unattached orientation and
• in an attached orientation after attachment of the first hydraulic hose and the tubular insert to the first device the tubular end section of the first seal rupturing structure physically ruptures the first seal of the tubular insert, and the first seal rupturing structure remains in the fixed position relative to the first device with the first device and first hydraulic hose in the attached orientation.
