Post Carry Co. expands its Speedpack Collection with new Slim Packs

Saigon/Amsterdam — For immediate release— Post Carry Co., the brand known for its versatile and reliable Transfer Case and the new Loomer bike case, is also expanding its line of frame bags with new, smaller sizes of the Slim Frame Pack and Slim Top Tube Pack.

These two bags are part of the Speedpack Collection and are designed for minimal packing and racing, able to handle rough weather and long days on the saddle, for riders who value speed and compactness.

The Slim Frame Pack, one of the narrowest frame bags on the market, has been offered for Medium and Large bike frames since its release in early 2025. The new XS size is the third frame bag size in the collection, and it fits bikes up to 52cm. At just 4cm wide, it can enhance the aerodynamics of a bike by allowing smoother air flow around the headtube, while allowing the rider to carry as much gear as required without a penalty. The narrow width also helps to avoid leg strikes while pedaling.

The Slim Top Tube Pack shares the same concept as the Frame Pack, with a 4cm width and an upper zip for easy access to all those items that need to be quickly reached on fast rides. The bag can be mounted via screw bosses on the top tube or using the included straps.

These bags utilize YKK waterproof zippers and feature cable ports to allow device charging or earbud routing. Plastic stiffeners ensure it stays straight and sag-free, even when fully loaded. All seams are RF seam-welded, making the bags water, sweat, and dust-proof.

The Slim Frame Pack was recently awarded Bicycling Magazine’s Gear of the Year award. As a stamp on Post Carry Co.'s design and quality, Factor has trusted Post Carry Co. to collaborate on a version of these Slim Packs for their new Sarana gravel bike, including them with any new purchase of the frame.

After the launch of the Loomer bike this year, this new announcement shows the growth path Post Carry Co. is on, where the ecosystem continues to grow based on vision, design, and quality.

The new size bags will be ready to ship in early June.
