Most listings list aluminum alloy as the primary material, and many also list plastic. A few specialty or aero-style listings note carbon-fiber components in addition to aluminum.

Fit ranges vary by model. Commonly holders accept diameters around 60–70 mm, and some adjustable models extend fit up to about 82 mm.

Weights vary by model. Listings show a rough range from about 0.1 pounds up to about 0.73 pounds. As an example, one aero-style carrier lists component weights of 70 g and 48 g (total 118 g). Check the product listing for the exact weight of the model you’re considering.

Check the product specs for thread and base-hole sizes. Common thread sizes in listings include M5x0.8 and base threads like M4x0.7, and some listings indicate base-hole diameters around 18–35 mm.

Adjustability varies by model. Some holders are adjustable and listings show fit ranges from about 60 mm up to approximately 82 mm to accommodate different bottle diameters.
