The Tacx Shiva is a classic and reliable water bottle that performs its function very well. It is made from plastic that does not affect the taste of water or other liquids stored in the container. The Tacx Shiva features a valve closure with a lock option, so there is no worry about leaks, even during particularly intense rides. The bottle's cap is designed for easy opening and closing, which will be especially appreciated while on the move. The designers have also optimized the diameter of the Tacx Shiva, making it easier to fill and clean.
