Two adjustable silicone straps fit bottles approximately 1.6–3.5 inches in diameter, including many cycling bottles, insulated flasks and other round containers. The adaptable design reduces the need to match one specific bottle shape to a traditional cage.
The magnetic-assisted buckle helps guide the bottle connector into position for faster alignment. Release the bottle with one hand, then return it to the mount without forcing it through a tight bottle cage.
Use the adjustable strap base on round or shaped tubes approximately 1.2–2.4 inches in diameter. Bikes with bottle-cage mounting points can use the supplied bolt-on base with 2.4–2.8-inch hole spacing.
Flexible silicone bottle straps create tension around different bottle diameters, while the padded contact surfaces help limit movement between the holder, bottle and frame. Check strap tension and buckle engagement before every ride.
The universal mounting system can be used on compatible bicycles, folding bikes, scooters and stroller tubes within the stated size range. Use a securely closed, leak-resistant bottle when mounting it horizontally or at an angle.
