All bottles age – even the TWIST bottles are not magic. Once the old bottle is worn down, the magnetic connector can be detached from the old bottle and is easily reattached to a new spare bottle. The modular system saves resources and also makes a bottle upgrade possible.
Features
Replacing the bottle is simple: Open the connector’s locking mechanism with a coin, attach it to the new replacement bottle, and close the locking mechanism.
 
Comes without bike mount and bottle connector.
