Ridea Bicycle Water Bottle Cage Adaptor

You can fit these bottle cage adapters to any circular-section tube on your bike (up to 35 mm in diameter), such as the seatpost, steerer tube, or top tube of your frame, allowing you to install a bottle cage in the most accessible position or carry extra drinks on hot days. The single-clamp design of the FCAS bottle cage adapter allows it to be installed on shorter tube sections, while the double-clamp design of the FCAD bottle cage adapter provides extra stability for your bottle cage.
