You can fit these bottle cage adaptors to any circular section tube of your bike (up to 35 mm), such as the seatpost, steering tube or top tube of your frame to install a bottle cage to keep your drink in the most reachable position for you or to carry even more drinks for those hot days.

The one-clamp design of the FCAS bottle cage adaptor allows it to be installed in shorter tube sections, while the two-clamp design of the FCAD bottle cage adaptor provides extra stability to your bottle cage.
