Extra long 2.1L top tube bikepacking bag with water-resistant nylon and adjustable compartments. Ideal for MTB and road bikes 18 inch frames.

Designed for extended frame setups, this extra long 2.1L top tube bikepacking bag maximises usable space on MTB and road bikes with 18 inch or larger frames. Its slim, low-profile design runs along the top tube, providing stable, easy-access storage without interfering with pedalling or handling.

Constructed from composite nylon fabric with a water-resistant coating, the outer layer helps repel light rain and road spray. While the material and zips resist moisture, stitched seams mean it is best suited for light showers rather than prolonged heavy rain. The reinforced internal structure improves tear resistance and durability during long-distance riding.

At 44 × 10 × 5.5 cm, the extended length allows improved weight distribution and efficient use of otherwise unused frame space. Adjustable internal compartments with Velcro dividers make it easy to customise storage for tools, nutrition, electronics, or small essentials. Elastic side pockets and smooth zip access improve organisation on the move.

Multiple secure straps fix the bag firmly to the frame, reducing movement over rough terrain. The narrow profile keeps knees clear, making it suitable for bikepacking, gravel riding, commuting, and endurance road cycling.

Built for riders who want efficient frame storage without bulk, this extra long top tube bag adds practical capacity to adventure-focused setups.
