Chapeau Tailfin it took along time for your frame bags to be available seeing them for so long on as prototypes with the likes of Lawrence Carpenter, Fernwee and Lachlan Morton…it paid off superb quality of straps, giving excellent frame attachment again Chapeau.

Top Tube Bag Zip 1.1litre

A great bit of kit used for 52 hours of the Dales Divide in torrential rain and mud.
Pros - Very waterproof, rock-solid, internal protection for electronics, no knee rub, stylish looks, easy to open one-handed.
Cons - annoying zip rattle, phone holder a bit baggy, quite hard to clean mud off completely.
Having used this bag over 280 miles of the DD, I found it very easy to use and totally waterproof. The protection inside was good but the phone holder didn’t really hold it securely and could do with being tighter. I used it with bolts rather than straps and it was completely solid. The rubber contact points are made for rounded tubes so on my flat Salsa top tube they contacted at four points and slightly wore the paint surface so a layer of heli-tape/Invisiframe would be useful.
The bag is quite tall in profile so the many, many gate openings around Yorkshire were occasionally very painful…
The surface was not the easiest to get completely clean of mud due to its texture.
The biggest gripe was the noisy zipper. It’s a shame that the bag is so totally solid and quiet in operation but the zip constantly jiggles. It really needs a little zip garage adding to finish it off.
All in all a great piece of kit and the flip top version is probably silent.

Great top tube bag

This 1,1 l top tube bag is great. It sits and stays just where I put it. Doesn’t sway even when standing on my pedals. No scratches when I took it of. I use it on road and gravel rides. Great place for my powerbank to charge my phone witch I use to navigate with. And for a pump, spare tube, multitool, tire levers and energy bars. It all fits and the bag stays in shape

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.
