Tube Bag MKIII

Acepac Tube Bag MKIII - compact 0.7 L top tube bag

Tube Bag MKIII is a small 0.7 L frame bag designed mainly for a spare tube, tyre levers, patches, a multitool and other basic repair equipment. Its compact shape makes use of the space near the rear of the top tube, while the low weight of just 65 g adds practical storage without unnecessary bulk.

The main material is lightweight and durable Nylon Robic with a PU coating rated to 1,500 mm H₂O. Access is provided by a water-resistant YKK zipper with a Hypalon pull tab that is easy to grip even while wearing gloves.

0.7 litres for essential repair gear

Tube Bag MKIII is designed for the small items worth carrying on every ride. The compact compartment can hold a spare tube, tyre levers, a puncture repair kit, multitool or CO₂ accessories.

Thanks to its small dimensions, it does not take up unnecessary space on the frame and can easily complement a larger frame, saddle or handlebar bag.

• capacity: 0.7 L
• weight: 65 g
• dimensions: 12 × 6 × 10 cm
• main material: Nylon Robic
• zipper: YKK

Organised interior

The inside features a bright-coloured lining that makes it easier to see and find smaller items. Internal mesh pockets help separate small accessories from the main contents.

Items such as patches, a chain link or compact tools therefore do not have to move freely around the spare tube and other equipment.

YKK zipper with Hypalon pull tab

The main compartment is accessed through a water-resistant YKK zipper. The slider is fitted with an extended Hypalon pull tab, making the bag easier to open while wearing gloves or in cold conditions.

The long opening also provides good access to the entire interior, so you do not have to search through the bag for the tool you need.

Adjustable frame attachment

Tube Bag MKIII attaches using adjustable Velcro straps positioned around the bottom and front of the bag. Their length can be adapted to the frame tubes, allowing the bag to sit securely in the available space.

The compact dimensions make it possible to use the area near the junction of the top tube and seat tube without occupying the entire frame triangle.

Lightweight and durable Nylon Robic

The main material is Nylon Robic with a PU coating rated to 1,500 mm H₂O. It combines low weight with good resistance to everyday mechanical wear caused by vibration and contact with the equipment inside.

Water-repellent, not waterproof

Nylon Robic with a PU coating and the water-resistant YKK zipper help protect the contents from light rain, splashing water and dirt.

The bag is not designed as a fully waterproof drybag. During prolonged or heavy rain, we recommend keeping moisture-sensitive equipment in a separate waterproof pouch.

Tube Bag or Tube Wrap?

Tube Bag MKIII is the better choice if you want to keep a spare tube and repair equipment enclosed inside a separate bag while using internal pockets for better organisation.

If you prefer the simplest and most minimalist solution for a tube, tyre levers and a basic puncture repair kit, an alternative is the Tube Wrap MKIII. For carrying more tools, you can also choose the Tool Wallet MKIII.
