ROTARY JOINT FOR BICYCLE HYDRAULIC CONTROL LINES

摘要: 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 together releasably the inside of head tube 7 cycle do not rotate relative tube. The sealed by seals on top side, slide around circumference when steering is turned, single circular cover 5 fork 6. hydraulics controls (rear brake, front sprocket selector mechanism, rear mechanism) channelled through chamber so that can rest bike, but mechanisms bike always possible because channel remains sealed. whole mechanism protected from collision damage dust/dirt corrosion.
