Fuel bag L MKIII

Acepac Fuel Bag L MKIII - 1.2 L top tube bag

Fuel Bag L MKIII is a practical 1.2 L top tube bag for items you want to keep within easy reach while riding. It is ideal for a phone, wallet, snacks, energy gels, tools or other small essentials that you do not want to search for inside larger frame bags.

Durable and lightweight Nylon Robic with a PU coating rated to 1,500 mm H₂O is complemented by water-resistant YKK zippers. The two zipper sliders are connected by a Hypalon loop, allowing you to operate both zippers simultaneously and open the bag with one hand.

1.2 litres for gear you want close at hand

The 1.2 L capacity provides plenty of room for everyday essentials on a day ride or a bikepacking trip. Its elongated shape makes efficient use of the space on the top tube while keeping the contents easy to access.

• capacity: 1.2 L
• weight: 125 g
• dimensions: 26 × 6 × 10 cm

Quick access through two YKK zippers

The main compartment is accessed through water-resistant YKK zippers. Their sliders are connected by a Hypalon loop, allowing both zippers to be operated together and the bag to be opened with one hand.

This is particularly useful for gear you reach for frequently, such as your phone, an energy bar or compact tools.

Organised interior

The inside of the bag features a bright-coloured lining that makes it easier to see the contents. Smaller items can be stored in internal mesh pockets, helping keep your gear organised and separated from the main load.

Fuel Bag L is therefore useful not only for food, but also for electronics, tools and other small items that you want to keep organised and easily accessible.

Side pockets for gels and small items

The external side pockets are ideal for energy bars, gels and other small items. Once used, they can also hold empty wrappers, helping you keep the trail clean without mixing waste with the rest of your gear.

This keeps the main compartment more organised while frequently used snacks remain easy to reach.

Stable attachment to the frame

Fuel Bag L MKIII attaches using adjustable Velcro straps positioned on the bottom and front of the bag. Contact areas are reinforced with Hypalon to increase durability in high-stress areas.

The straps can be adjusted to suit the specific frame, helping the bag sit securely on the top tube and remain stable while riding.

The Grey version can be bolted directly to the frame

The Grey version features perforated holes in the bottom, allowing the bag to be bolted directly to a compatible frame. If your bike has suitable mounting points on the top tube, this can reduce the number of straps needed.

This mounting option is available only on the Grey version.

Water-repellent, not waterproof

The main Nylon Robic material with a 1,500 mm H₂O PU coating and water-resistant YKK zippers help protect the contents from light rain, splashing water and dirt.

The bag is not designed to be fully waterproof. During prolonged or heavy rain, we recommend protecting your phone, electronics and other moisture-sensitive equipment in a separate waterproof pouch.

Fuel Bag M, L or XL?

Fuel Bag L MKIII is the medium-sized version with a capacity of 1.2 L. If you want a smaller and lighter bag for basic essentials, choose the Fuel Bag M MKIII with a capacity of 0.8 L.

For more gear, the larger Fuel Bag XL MKIII offers a maximum capacity of 2 L. This allows you to choose the size according to the amount of gear you carry and the available space on your frame.
