Rock solid well designed bag!

I bought the 1.1 litre flip top bag for my gravel bike to replace a top tube bag from another brand where the zip had failed. This bag is so much better, more stable and much easier to access snacks on the move. There is some knee rub when I'm pedalling when out of the saddle but much less than my previous bag. It's not really an issue as I'm usually seated. Great design!

Excellent product

I had the 1.1 litre top tube bag for my new bike, I wanted something robust and waterproof for my up coming Great Divide trip. I love the strap system, it attaches to my Ti Frame without any movement. It will house my electric's from my dynamo, so l went for the flip lid for better water protection. I'm very happy with it and highly recommend it.

Tailfin top tube bag, flip top

Awesome bag, before purchase I read some reviews that say you need two hands to use it, one to keep it open and one to dig for what you want to take out. That is not at all true, very happy. An unexpected advantage over my previous bag is how easy it is to put on and take of the bike. So I tend to take it on all my rides (5 bikes) and when bikepacking this is also a nice bonus. It is a little bulky compared to most other bags, but the extra space is worth it, when the headlight or headunit runs out of power I can just throw in a powerbank. When standing on the pedals in a sprint or climb I do get some kneerub on the closure.

FAQs

Yes, the V-Mounts can accommodate any standard 20mm width cargo style strap. However be aware that many cargo straps use a longer prong that could catch skin or clothing.

Absolutely. Even when pulled very tight the natural stretch of our Cargo Strap system exerts minimal force to the frame.

You should base your choice on which bike you are mainly going to use and also how much storage you would typically need. Our 1.1 Litre Top Tube Packs are designed to fit almost any style of bike so would be our recommendation to be used on multiple bikes.

Our Zip Top Tube Packs offer the narrowest profiles so are perfect for riders who typically suffer from knee rub from top tube packs. They also offer the most secure storage to carry valuables on rough surfaces. Our Flip Top packs allow for rapid access and great visibility of contents, perfect if you want constant access to food, phone or camera whilst on the move. Flip Tops also offer slightly better weather resistance if riding in constant storm conditions.

No! When attached correctly the soft rubber of the V-Mount grips the frame so well that there is zero likelihood of movement.

We were at pains to ensure that all sizes of Top Tube Pack can accommodate a standard iPhone or Android equivalent, even the smallest 0.8 Litre pack. If you have a larger (Plus) style phone you will need to look at the 1.1 Litre or 1.5 Litre Top Tube Packs.

Within reason you can carry any weight in a Top Tube Pack. The limit would be volume.

Although the packs have been shaped to fit perfectly on the top tube the V-Mount system will allow you to fit a Top Tube Pack anywhere (except forks). We would recommend this only for Zip opening packs as a Flip Top opening would not be as secure in a vertical orientation.

The straps supplied with the Top Tube Packs are low profile so shouldn’t interfere with standard frame pump fittings.

As with all Tailfin soft goods we recommend that they be washed with warm soapy water if you want to clean them (although we like a good dirt patina!)

No, the rubber V-Mount covers are pre-cut to allow screws to pass through neatly.
