Almsthre Signature Frame Bag

The Almsthre Signature Frame Bag delivers versatile on-bike storage with organized compartments and adaptable fitment for adventure riding.

Designed as a true do-it-all storage solution, the Almsthre Signature Frame Bag combines smart organization, weather-resistant construction, and flexible mounting compatibility for road, gravel, bikepacking, and everyday riding. Available in multiple sizes, the bag integrates cleanly into a wide range of frame designs while maximizing storage capacity without compromising ride stability.

Its thoughtfully designed three-compartment layout separates ride essentials for improved organization on long rides and multi-hour adventures. A dedicated rear “garage” compartment is specifically intended for tools, tubes, and repair items, keeping heavier or dirtier gear isolated from snacks, electronics, cameras, or extra layers stored in the front compartments.

Constructed from durable premium ripstop fabric with waterproof zippers, the Signature Frame Bag is built to withstand changing weather conditions, road spray, and rough terrain. The slim 2-inch profile helps reduce knee interference while maintaining a stable and balanced fit inside the frame triangle.

A continuous loop webbing system runs across the front, top, and rear sections of the bag, allowing riders to fully customize strap placement depending on frame geometry, cable routing, or mounting preferences. Included trim-to-length hook-and-loop straps provide a clean and secure installation tailored specifically to each bike setup.

The Small/Medium version offers 1.6 liters of storage and is recommended for frame sizes 50cm and larger, while the Large/XL version expands capacity to 2.3 liters for bikes sized 56cm and above. Both sizes are engineered to provide efficient, stable storage for long rides, daily training, and lightweight bikepacking adventures.
