Fuel Bag M MKIII

Acepac Fuel Bag M MKIII - compact 0.8 L top tube bag

Fuel Bag M MKIII is a compact 0.8 L top tube bag for a phone, snacks, tools and other small essentials you want to keep within easy reach while riding. Its smaller dimensions make it a great choice for minimalist bikepacking setups, shorter rides or bikes where you want to keep the top tube area as uncluttered as possible.

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

0.8 litres for everyday essentials

The 0.8 L capacity is ideal for a phone, wallet, energy bars, gels, compact tools or other small items that you want to access frequently while riding.

Fuel Bag M takes up less space than the larger versions, making it suitable for smaller frames or riders who only need a compact storage space on the top tube.

• capacity: 0.8 L
• weight: 105 g
• dimensions: 19 × 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 items 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.

Despite its compact dimensions, the Fuel Bag M provides a practical and well-organised storage space for small essentials.

Side pockets for snacks 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 so you do not have to store them inside the main compartment.

This keeps frequently used snacks within easy reach while helping the main compartment stay organised.

Four adjustable straps for secure attachment

Fuel Bag M MKIII attaches to the frame using four adjustable Velcro straps. The bottom and front contact areas are reinforced with Hypalon to improve durability in high-stress areas.

The adjustable strap positions make it easier to adapt the bag to a particular frame and keep it securely positioned on the top tube while riding.

Option to bolt the bag directly to the frame

The latest Fuel Bag M MKIII features perforated mounting holes in the bottom, allowing the bag to be bolted directly to a compatible frame with suitable mounting points.

This mounting method can reduce the need for lower straps and provides a clean and stable installation.

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.
