Arundel STR-Mandible Sideloader 3K Matte (Right Side Entry, Seat Tube Mount).

The Arundel STR Mandible Sideloader is a carbon side-entry bottle cage built for seat tube mounting, with a 3K weave matte finish. Right-side entry allows the bottle to slide out sideways, which helps on small frames, full-suspension bikes, and bikes with frame bags where lifting a bottle straight up is difficult. The Mandible design holds the bottle securely on rough roads and gravel. Arundel's carbon construction keeps weight low while staying strong and durable. It pairs with the DTR-3K Mandible OtherSideloader for a matched setup on both bottle mounts.
