Behind Saddle Rear Hydration System

Valdora's rear hydration system consists of a multi use rack that attaches to the saddle rails and keeps your bottles out of the wind, minimizing drag.  Unlike other behind saddle systems on the market, Valdora's behind saddle bottle rack offers multiple configurations.  At 100 grams the hydro rack weighs less than the closest competitors. A must for long training rides. An extra bottle to replenish your 'between the aerobar' bottle during races. Maybe a shot of the hi carb nutrition that you will need. Or a modified bottle to carry an extra tube, tools, patch kit....what ever you can think of, carry it here. A competitor should not train or race without a Valdora hydro rack. Light weight cnc'd alloy, tough, easy to install, easy to adjust.  Everything you need to train and race with confidence!


  • Configurations:  One, two or three bottles.  Threaded holes for CO2 cartridges, or carry two bottles, CO2 cartridges and attach a popular flashing tail light.
  • Additional 5 m bottle boss sized threaded holes are included in the rack for other attachments you may desire at a later time.  What is the most popular configuration?
  • Two bottle cages, two CO2 cartridges (not included), and solid / flashing bright red LED tail light.
  • Construction:  Light weight machined 6061 alloy.
  • Adjustable:  Adjust the angle that the rack sits at based on road bike or tri bike geometry.

  • Weight:  100 grams
  • Size:  Fits any saddle with standard, round rails (Note - attaches to horizontal section of saddle rails behind seat post clamp.)
