bike bottle cage

The listings show two common materials: plastic and aluminum alloy. Product details repeatedly list either “Material: Plastic” or “Material: Aluminum Alloy.”

Compatibility varies by model. Example cup-diameter ranges from the listings include 55–72 mm, 56–70 mm, 60–70 mm, and up to 60–82 mm.

Cages can be mounted to a seat post and many models also offer a handlebar mount or include a removable base so the cage can attach to the handlebar or a seat-post/base mounting point.

Packages often include mounting hardware such as screws and a small wrench; some also include a mounting base and gaskets. Example listings show items like 2 screws plus 1 wrench or 4 screws plus 2 wrenches and a base.

Weights vary by material and design. Example listings show lighter aluminum cages around 0.11 pounds and some plastic holders up to about 0.39 pounds, so the observed range is roughly 0.11–0.39 lb.

Thread sizes shown in the listings include M4 × 0.7 and M5 × 0.8. Mounting-hole center-to-center spacings reported in product details include examples like 5.5 cm and 6.5 cm.

Compatibility varies by mount base. Example fit ranges in the listings include 14–26 mm and 18–40 mm, so across the results documented base-fit diameters span roughly 14–40 mm.

Installation is usually with screws tightened by a small wrench. Many products include the screws and a wrench and note mounting to a seat post or to a handlebar using an included base or fasteners.
