What is a Top Tube Bag?

Whether you're new to bikepacking or a seasoned veteran, a top tube bag is an essential item for your gear list. The concept of the top tube bag isn’t new. Before modern bikepacking, smaller versions known as "bento boxes" were used by a variety of athletes on endurance missions. These bags have evolved, and today's designs are more versatile and functional.

It's a bag mounted to the top tube and head tube of your bike, using bolts, straps, or paracord. There are many different styles with a variety of closure mechanisms. Some use an elastic band and magnetic closure system, while others feature a classic zipper. The purpose of a top tube bag is to provide quick access to items such as snacks, phones, electrolytes, and other essentials you need while riding.

Top tube bags are designed for quick access to items without having to stop and dismount. This can be especially beneficial for long-distance riders or those navigating rough terrain. Here are some benefits of using a top tube bag:

• Convenience: Easy access to essentials like snacks, phones, and tools.
• Accessibility: Designed to be opened with one hand while riding.
• Organization: Keeps small items organized and within reach.

• Mounting Points: Does your bike have mounting points? Some bags bolt directly to the frame, while others use straps.
• Volume: How much space do you need? Top tube bags come in various sizes.
• Waterproofing: Is waterproofing a must for you? Consider your riding conditions.
• Dimensions: Consider the length and width to ensure it fits your bike and doesn't interfere with your ride.
  • Larger bags may be less stable than smaller ones.
  • Wider bags might graze your knees, especially during cornering.
• Fasteners: Some bags have fixed fasteners, which are usually more stable, while others are adjustable. Fixed fasteners can provide a more secure fit, but adjustable straps offer more flexibility in mounting.

• Main Compartment: A single main compartment with a zipper closure.
• Cable Port: Allows you to run power to a GPS or handlebar-mounted device, which is a handy feature for long rides.

The bag has a structured exterior to maintain its shape, whether full or empty, and holds up to 0.25 liters with a weight of 355 grams. My favorite feature of this collection is the waterproof RF-welded construction. Additionally, the bag is made from 100% recycled nylon fabrics, which is a great nod to sustainability.
