Apidura Backcountry Dropper Post Adapter, MTB (30.9/31.6/34.9mm)

Available from Good Weather Bicycle when we last checked. Sold from the shop’s own store; the price there is the one that counts.

A dropper post adapter for saddle bags, designed to limit travel and prevent damage to the post or bag. The Backcountry Dropper Post Adapter offers enhanced stability on challenging terrain thanks to a flat rear section and ridged strap retainer. It is designed to integrate with the Backcountry Saddle Pack and any other bag using a 25mm seatpost strap, maintaining clearance between bag and wheel. Installs quickly with a 3mm hex wrench; the MTB version includes shims to fit 30.9mm, 31.6mm and 34.
