Apidura Expedition Stem Pack – 1.3L
The Apidura Expedition Stem Pack is a fully waterproof, seam-welded 1.3 L stem bag with a Fidlock magnetic snap closure for secure, one-handed access while riding. It weighs 120 g, mounts with a three-point system on either side of the cockpit, and can also be fitted to racks or baskets.
Why a stem bag – and why this one
Food, a phone or a camera are most useful when you can reach them without stopping. A stem pack keeps them right beside your hands. The Expedition Stem Pack solves the usual problems of simple stem bags:
- It opens and closes with one hand. The Fidlock magnetic snap closure gives easy access on the move and keeps the contents secure.
- It does not rattle when half empty. The compressible design adjusts the pack size to suit the contents, improving stability.
- Your knees stay clear. A subtly tapered shape avoids knee contact when pedalling.
- Your gear stays dry. Waterproof materials and RF-welded seams make the pack 100% waterproof.
- It fits more than one place. The three-point system adapts to different bar and stem combinations, and vertical and horizontal mounting points allow attachment to racks, baskets and other hardware.
Who is it for?
- Gravel and road riders who want snacks within reach without stopping.
- Bikepackers and tourers building a weatherproof setup with the Expedition series.
- Commuters and everyday riders who want a dry, quick-access pocket on the cockpit, a rack or a basket.
