Tailfin develops a waterproof bag storage system designed specifically around Cargo Cages

British bikepacking gear brand Tailfin have taken their technical, problem-solving approach to dry bags with the release of their Cage Pack range from 1.7 liters to 5 liters capacity, alongside Cargo Straps.

“It’s common knowledge that the easiest method to get more kit on your bike is to attach a dry bag to a rack, frame tube, or cargo cage,” says Tailfin. “It’s a technique that, while excellent enough to deliver increased volume without the need for a ton of technical equipment, unfortunately also has many downsides.”

But now Tailfin feels it has a solution that provides a strong, secure and consistent fit for this system to work effectively with its Cargo Cages, as well as those from other brands.

Review: Tailfin Cargo Cage

Pack of cages

Tailfin’s new Cage Pack range is designed to work as seamlessly as possible with its existing Cargo Cages and in doing so create a complete storage system.

In terms of size, you have the choice between three. The smaller 1.7 liter Cage Pack is intended to be positioned inside the frame triangle and under the down tube, the 3 liter packs would be ideal for small loads on the forks and on the rear racks , then there is the larger 5 liter bag which is suitable for larger loads.

Unlike traditional dry bags, Tailfin has shaped the Cage Packs with flat side panels to minimize rider interference when used inside the frame or under the downtube.

It’s the Speed ​​Hook Loading System that makes the Cage Pack unique. “We specifically created the Speed ​​Hook system to eliminate the cumbersome nature of traditional ‘daisy chain’ style closed webbing guide loop systems commonly found on existing bike dry bags,” says Tailfin.

“After many years of dealing with the problem of having to completely unscrew the straps of the cage with a daisy-chain style bag in order to remove it from the cage, the new Speed ​​Hook system is a revelation.”

The open design of the Speed ​​Hook is said to allow you to semi-install your straps and just guide the bag. Tailfin claims that it provides a secure grip on the bag even when using load cages without a platform.

The strap hooks are constructed using a flexible yet strong TPU and are individually welded to the pack.

Tailfin explains that they chose to weld rather than mechanically fasten (sewn or with screws/bolts) because “this technique creates the lowest, durable and guaranteed waterproof approach to integrating the material into a soft bag”.

As the pack is intended for use with a Cargo Cage, Tailfin chose to produce the Cage Pack without an internal frame as the pack can use the cage instead for the structure it needs to hold the load stable.

“We felt this was beneficial for maximizing load capacity, regardless of the often odd shape of the bikepacking kit,” says Tailfin. “It also increases compliance with the multitude of cage shapes found in the bikepacking world.”

Heavy duty 420D Hypalon laminate has been used in high wear areas whilst lighter and more flexible ripstop nylon can be found in all other areas with the idea that this creates a very conformable shape.

The roll-top closure is designed to provide easy, weather-resistant access and, as with all Tailfin technical bike bags, the Cage Pack has been constructed using a process of welding the fabrics together to create a completely waterproof and weatherproof package. sewing – Tailfin claims it. The construction method ensures that the Cage Packs are 100% waterproof.

The larger 5 liter Cage Pack also comes with additional T Hook compression straps to reduce pack length or compress soft contents.

While Tailfin designed the Cage Pack to work perfectly with their own Cargo Cages, the brand says they pair equally well with any brand of cargo cage.

The strap hooks have been spaced to align with the strap guides found on the cargo cages, but this spacing is also compatible with any strap arrangement. Plus, the strap hooks accept any brand of load strap up to 25mm in width.

Loading straps

Alongside the release of the new Cage Packs, Tailfin is now producing its own Cargo Strap range inspired by ski straps.

“Rather than simply copy and paste the classic design, we have invested considerable R&D to deliver specific benefits of our load lock buckle design and material selection,” says Tailfin.

“The shape of the buckle has bicycle frame tube profiles in mind, and the entire strap uses non-scratch materials.”

A specially adapted TPU (thermoplastic polyurethane) material has been used for the straps.

“The compound balances stretch, grip, and strength while performing consistently over a wide temperature range,” says Tailfin. “It is also highly abrasion resistant, providing reliable resistance to damage.

Tailfin says this need for strength also led him to use 6/6 nylon for the Load Lock buckle.
“This material is almost indestructible, you can smash it with a rock or hit it with a hammer, and it will spring back into shape without breaking a sweat,” claims the brand.

The hook and eye interface was designed to work best with soft bags and packable loads, and is meant to help provide efficient and positive engagement.

“The design incorporates a self-locking mechanism that holds firmly even when the contents of your bag change; a technical feature that creates peace of mind even on rough terrain,” adds Tailfin.

Another nice feature is that the eyelets run almost the full length of the strap to maximize usable length.

Cargo straps are available in the standard 20mm width to ensure a universal fit with all cages and cargo bags.

Three lengths are also available: 40, 50 and 65cm for compatibility with all bag and cargo sizes.
