TWIST single bottle (no base) The bottle comes without the bottle mount for the bike – perfect to retrofit if the bike is already equipped with the TWIST bike base or the TWIST uni base. 450 ml, 590ml and 600ml volume Dishwasher-safe BPA-free polypropylene Fits all TWIST bases Comes without base Strong magnets attract, center, and latch different modules magnetically to the base. The mechanical locking keeps the module securely attached to the frame. This ensures comfortable and safe handling, even under strain. TWIST modules can only be removed with one simple “TWIST” to the side. Even small and tight frames that offer no space for conventional bottle holder cages can be equipped with a water bottle.
