Very pleased

Bought this as an extra option to carry things on longer trips. Fits my phone, lots of snacks and other crucial things. I got the 0,8L and it fits the frame well and no knee rubbing

Nice but phone pocket must be improved

Nice construction, V-mounts hold securely, padded interior is useful, not too expensive BUT I bought it specifically for the phone pocket and I am very disappointed.
The phone is not held tight at all and the pocket isn't padded enough to protect it from the vibrations. The pocket works alright when the bag is full, but doesn't work at all when it's empty, which is a shame. I resorted to stuffing the bag with various stuff to hold my phone in place, which isn't sexy. All in all, looks like the accessory pocket from the long top tube bags would be better, but I have no way to be sure

To be fair, Tailfin doesn't market this as a phone pocket, and I understand why

Hi Antoine,

Thanks for taking the time to leave us a review, we really value your feedback and I'm sorry that you had this issue. I've also contacted you directly via email to see if we can help resolve this for you! All the best, Poppy

London 2 Barcelona Ride

I bought the 1.1ltr Tailfin top tube bag for a London 2 Barcelona group ride (1-13th June 2025). So glad I did, as perfect size for keeping my phone in, along with snacks, sweets etc.
One of the days we had torrential rain and everything within the bag remained dry, unlike the rider!
Easy to fit. Great product and highly reccommend.

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.
