From the handle to the hose and baffles to the bite valve, we thought through every interaction and aspect of our Hydraulics design to identify opportunities for a better user experience—redesigning, reshaping and updating to create our best reservoir series yet. We paired the Hydraulics LT 1.5L Lumbar Reservoir with Seral/Savu, our premium biking hydration lumbar pack series. Ideal for riders who prefer off-the-back carries, this hydration solution allows you to ride freely over the most technical, steep terrain and keep your water flowing and close at hand all day.
