Handy storage for items needed on the go, in a place that’s instantly accessible.

Tailfin Top Tube Bag (Zip)

Such a great-quality bag! Large enough to hold my phone and snacks and great to have them out front, being more accessible, yet compact not to be rubbing on my legs while cycling! Very easy to attach to bike either with the straps or screws. Happy with my purchase!

Excellent top tube bag!

I’ve been looking for a bolt-on top tube bag that was big enough but not too big. The range of sizes of the Tailfin bags was perfect. Very happy overall with the build quality and features. Only complaint was the drumming noise the zipper-pull made bumping along gravel roads. Fixed easily with some paracord.

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.
