Bike Bags & Mounts Tern

Tern Bottle Cage Boss Designed specifically to secure water bottles on bikes with more horizontal top tubes, the Tern Bottle Cage Boss Fitting has flexible arms that grip the bottle and hold it in place. The polycarbonate construction is light and strong, and won’t mark stainless steel bottles.

Tern Bossless Bottle Cage with Velcro Perfect for frames without cage mounts or for additional hydration capacity, the Bossless Bottle Cage with Velcro from Tern can be mounted on any tube with a diameter of 22-41mm. The sprung arms of the cage grip the bottle for a secure and rattle-free fit whilst the rubber base ensures that the cage doesn’t slip around the tube or seatpost.
