Bike frame bag Rockbros AS-019-1 — waterproof 1.6L, black

Rockbros AS-019-1 is a waterproof bike frame bag with a 1.6‑liter capacity in black, designed to fit inside the main triangle of most bicycles. The bag keeps small items such as tools, a phone, snacks and personal effects protected from rain and road spray while remaining compact and lightweight. Its shaped profile follows the frame lines to minimize interference with pedaling and steering.

Advantages

The waterproof construction and sealed zippers provide reliable protection against moisture and dust. Adjustable fastening straps secure the bag to top tube and down tube contact points to prevent shifting during rides. The internal layout is simple and unobtrusive, allowing quick access to essentials without removing the bag. Durable materials and reinforced stitching improve resistance to wear from regular use.

Suitable for

• Daily commutes where a compact dry storage solution is needed
• Road cycling and training rides requiring lightweight equipment storage
• Gravel and off‑road trips where protection from rain and splash is important
• Short touring or bikepacking stages with limited carry needs

How to use

Position the bag inside the main triangle and align it so it does not interfere with the crank or steering. Fasten the adjustable straps around the top tube and down tube, tightening until the bag is stable and does not rotate. Store tools, a phone, spare tube or snacks inside the main compartment, and close the waterproof zipper fully before exposure to wet conditions. For cleaning, wipe the exterior with a damp cloth and allow to air dry; avoid submerging the bag.

Usage recommendations

When loading heavier items, place them close to the frame to maintain bike balance. Check strap tightness before each ride and avoid overfilling to ensure the zipper seals properly. For prolonged exposure to heavy rain, inspect seams periodically and allow the bag to dry thoroughly after use.
