To assemble the lightest aerobar hydration system, the XLAB Torpedo Mini Mount Carbon will be the first essential building block. You then just need to add the Torpedo Carbon Cage, and then you can use it with your normal water bottle. And if you like that setup, then eventually you may like to go the whole hog and treat yourself to the Torpedo Refill Upgrade Kit which will give you the aero advantage of the Torpedo water bottle as well as the practicality of being able to refill on the go and drinking without having to take your hands off the bars. Made from Carbon Fiber with proprietary unidirectional fiber orientation, the Mini Carbon Mount fits bars that are 8cm-13cm apart, measured center-to-center. The XLAB Torpedo Mini Mount Carbon comes with carbon fiber plate and four silicone coated, non-stretch polyester straps as well as two M5x12 mounting screws, washers and Nyloc nuts. Weighing only 19g, you will have a lightweight solution to your hydration whether you are preparing for an important race or just want to have the means to drink your water safely without having to remove your hands from the aerobars.
