Tube bag MKII

Acepac Tube Bag MKII - compact 0.7 L top tube bag

Tube Bag MKII is a compact 0.7 L frame bag designed mainly for a spare tube, tyre levers, patches, a multitool and other basic repair equipment. Its small dimensions make efficient use of the top tube area without taking up unnecessary space inside the frame triangle.

The lightweight construction is made from Nylon 6.6 with a PU coating rated to 1,500 mm H₂O and weighs just 60 g. 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

The 0.7 L capacity is ideal for equipment worth carrying on every ride. The bag can hold a spare tube, tyre levers, patches, a small multitool, a chain link or other compact repair essentials.

Its compact shape keeps your repair gear separate from the rest of your equipment and leaves larger bags available for food, clothing or gear for longer trips.

• capacity: 0.7 L
• weight: 60 g
• dimensions: 12 × 6 × 10 cm
• main material: Nylon 6.6
• zipper: water-resistant YKK

Organised interior

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

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

Water-resistant YKK zipper with Hypalon pull tab

The main compartment is accessed through a water-resistant YKK zipper. The extended Hypalon pull tab makes the zipper easier to operate while wearing gloves or in cold conditions.

The long opening also provides good access to the entire compartment, allowing you to reach your repair equipment quickly.

Adjustable straps for different frames

Tube Bag MKII attaches using long Velcro straps positioned on the bottom and front of the bag. Their length can be adapted to the specific frame, and any excess can be trimmed after the final position has been tested.

Before shortening the straps, we recommend loading the bag, fitting it to the bike and checking the required strap length carefully.

Padded perimeter for better protection

The perimeter of the bag is padded, helping it maintain its shape while providing partial protection for the contents against vibration and impacts during the ride.

The bag also features a reflective logo that improves visibility when illuminated in low-light conditions.

Lightweight Nylon 6.6

Tube Bag MKII is made from Nylon 6.6 with a PU coating rated to 1,500 mm H₂O. This durable synthetic fabric is well suited to lightweight cycling bags where low weight and resistance to everyday mechanical wear are both important.

Water-repellent, not waterproof

Nylon 6.6 with a PU coating and the water-resistant YKK zipper help protect the contents from light rain and splashing water.

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