The Almsthre Compact Frame Bag uses a two-compartment design that keeps your gear organized without consuming the entire front triangle of your frame. The bag measures eight and a half inches long by two inches wide by three and a half inches tall, providing 0.9 liters of capacity while leaving clearance for large water bottles in your bottle cages. This compact footprint works on frames with aggressive geometry where full-size frame bags create knee clearance issues or block bottle access. The bag mounts using three trim-to-length velcro straps that wrap around your top tube, down tube, and seat tube, with three adjustable strap locations that accommodate different frame sizes and shapes.

Dual waterproof zippers open the bag from both sides, which gives you access to either compartment without reaching across the frame or dismounting. An internal divider separates the two main sections, keeping tools away from food or electronics. The bag includes a credit card slot for quick access to payment without digging through your gear, plus an internal mesh pocket for organizing small items like keys or tire levers. A high-visibility liner helps you locate items quickly when you unzip the bag during rides or in low light conditions.

The ripstop nylon construction with weather-resistant finish sheds water during light rain and protects contents from road spray. The material resists tears from frame contact or sharp tool edges, and reinforced wear points prevent premature failure where the mounting straps attach. The slim profile keeps the bag aerodynamic without creating a bulky presence between your legs during pedaling, even on frames with steep seat tube angles or compact rear triangles.
