Minimalist saddle bag for essentialist riders

The ALM150 Compact Saddle Bag is built for cyclists who value simplicity and ultra-light travel. It weighs only 45 grams and carries 0.3 liters of gear beneath the seat. Water-resistant ripstop fabric and a waterproof zipper protect contents from road spray. Riders needing more storage or a larger profile should look elsewhere.

0.3 litre capacity with internal organisation

The bag measures 3 inches wide by 4.25 inches long by 1.25 inches tall, making it 40 percent smaller than the brand's Signature model. An internal pocket and high-visibility liner keep small items separated and easy to locate. The volume handles a tube, multi-tool and patch kit, but runs out quickly if you add a phone or light jacket.

Adjustable seat-rail mount for quick installation

A single adjustable strap secures the bag to standard saddle rails without tools. The compact footprint leaves ample clearance for dropper posts and wide tyres. No additional mounts or frame straps are required, freeing up handlebar and frame space for lights or navigation.

Questions about this item

Will the ALM150 saddle bag fit alongside a wider saddle or seat post clamp I already have?

The bag mounts with an adjustable seat rail strap measuring 1.25" tall by 4.25" long, so it clears most standard rails and leaves room for common clamps.

How can I confirm the waterproof zipper and water-resistant ripstop are performing after my first wet ride?

Open the bag and check the high-visibility liner — contents should stay dry and the interior pocket shows no moisture penetration.

What comes in the box with the ALM150 and do I need any extra straps or tools?

The package includes the 0.3L saddle bag with integrated adjustable seat rail strap; no additional hardware or tools are required for installation.
