The POC Ultra Top Tube Bag 1.7L is a top tube bag designed to keep essentials within easy reach on long rides, gravel events, and ultra-distance.

Format and access

With a volume of 1.7 litres and a claimed weight of 170 g, it offers more capacity than a small bento box without becoming excessive on top of the frame. The long zip makes it easy to access the contents, even with one hand.

Stability and organisation

• Reinforced base to limit deformation.
• Structured sides with minimal lateral play observed in use.
• Internal side pockets to separate small accessories.
• Front cable port for a power bank or lighting.

Mounting

The bag can be mounted with straps or using a bolt-on mount depending on the frame. Even bolted on, a rear strap is still needed to stabilise it properly.

Our take

This is the most convincing model in the range we tested. Its volume, stability, and easy access make it a compelling option for ultra-distance. The only notable caveat: the elastic by the stem sits quite high, which can complicate installation on a very short steerer tube.

The POC Ultra Frame Bag 3L is a frame bag designed to increase carrying capacity while keeping weight low on the bike. It targets long gravel rides, light bikepacking, and ultra-distance setups.

Volume and construction

With 3 litres of volume and a claimed weight of 220 g, it lets you carry tools, nutrition, a power bank, a compressible layer, or small gear. Its internal structure helps it maintain a slim, stable shape.

On-bike stability

• Hypalon straps to hold the bag tight against the frame.
• Rigid structure limiting unwanted movement.
• Small internal pockets to organise part of the contents.
• Cable port compatible with a power bank or dynamo, depending on the setup.

Compatibility to check

On many modern gravel bikes, bottle access may require side-entry cages. The stock straps may also be tight on some very thick or profiled down tubes.

Our take

Stability and finish are very well executed, but the opening placed high on the bag is less convenient once mounted on the bike. A second side opening would also have made organisation easier on long distances.

The POC Ultra Bar Bag 4L is a compact handlebar bag designed to add accessible storage space on long gravel rides or adventure days.

Format

It offers 4 litres of volume and a claimed weight of 300 g. Its slightly tapered cubic shape differs from a classic handlebar roll and aims to reduce frontal bulk while keeping quick access to the contents.

Organisation

• U-shaped zip opening for easy visibility of contents.
• Internal mesh pockets to stabilise small items.
• Cable port for a power bank or front light.
• Reflective details integrated on visible areas.

Recommended use

This bag works well for carrying nutrition, a jacket, a power bank, or accessories you want to keep accessible. Its shape is less suited to bulky, compressible items like a sleeping bag or a bivvy.

Our take

It is an interesting option as a standalone front storage solution for a big ride. In a full bikepacking setup, it seems less versatile than a more elongated format or a system dedicated to sleep kit.
