Apidura Dropper Post Adapter (for Backcountry Saddle Packs)

The Backcountry Dropper Post Adapter provides stability for saddle bags on technical terrain through a flat rear section and ridged strap retainer. This component maintains necessary clearance between the bag and wheel while protecting the seat post from potential damage. It integrates with the Backcountry Saddle Pack and various other bags that use a 25mm seat post strap system during rides.

Installation requires a 3mm hex wrench for a secure fit on the dropper post stanchion. The MTB version includes shims for 30.9mm, 31.6mm, and 34.9mm diameters. The Gravel version fits 27.2mm stanchions specifically. These options ensure the adapter stays in place on different bike types while limiting travel to prevent contact between the bag and the rear tire.
