A rotary fluid connector for hydraulic control lines in a bicycle, has multiple chambers 1, 2 and 3 which are concentrically fixed to each other and together releasably fixed to the inside of the head tube 7 of the cycle and do not rotate relative to the head tube. The chambers are sealed by seals on the top side, which slide around the circumference of the chambers when the steering is turned, which are fixed to a single circular cover 5 which is fixed to the fork tube 6. The hydraulics of the controls (rear brake, front sprocket selector mechanism, rear sprocket selector mechanism) are channelled through a chamber so that the steering can rotate relative to the rest of the bike, but control of mechanisms on the rest of the bike is always possible because each hydraulic channel remains sealed. The whole mechanism is protected by the head tube from collision damage and dust/dirt corrosion. <IMAGE> |
