Apidura Dropper Post Collar/Adapter (for Backcountry Saddle Packs)

This custom-made Dropper Post Adapter allows Backcountry Saddle Packs to be used on mountain bike dropper seatposts. The adapter is designed to hold the pack securely, while also limiting travel to avoid damage to either the post or the bag.

Comes with a choice of shims for dropper posts with 30.9mm, 31.6mm and 34.9mm lower diameters and is easily fitted using a 3mm hex wrench. The broad, flat rear section and ridged strap retainer improve stability over rough terrain and the adapter is also compatible with any bag that uses a 25mm seat post strap (or smaller).

- Designed to work with MTB dropper posts with a 25mm or 26mm upper section diameter
- Injection moulded glass-reinforced nylon for durability
