The Tacx Shiva 500 ml is the new water bottle of the Pro teams. This good-looking bottle is easy to squeeze, making it simple to drink while riding. The Shiva has a large twisting top with a leak-proof drinking spout. The large twisting top makes it easy to clean and fill the Shiva. Matches nicely with the Uma bottle cage when it comes to the design. This Tacx Shiva is environmentally friendly as it's bio-degradable.
