Top Tube Bag – Zip

From: £52.00

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

Specially sculpted 3D welded shapes eliminate knee rub. Patented V-Mounts secure the pack to your frame without risk of damage and remove the need for a front stabilising strap.

All Top Tube Packs can be fitted with straps or as a bolt-on attachment (all hardware supplied).

Petite mais grande

J'ai opter pour une tailfin top tube bag 1L , et c'est vraiment le top , j'ai un canyon grizl auxquels elles se prêtent vraiment bien. Dedans j'y loge : iPhone 14 pro , chambre à air , mèche + outils , multi outils , des pâtes de fruit , mes clef de maison et je peux encore loger 1 petit truc.

J'ai pris le modèle avec fermeture éclair bien pratique pour ne pas tout faire tomber quand on ouvre en roulant. La finition et la qualité sont vraiment au rendez-vous , certe un peu chère mais aucune marque ne propose avec une tel fixation et un tel Dev. Pour ma part je l'effleure en danseuse , beaucoup se pose la question.

A bientôt

Works well and rain tested

I have not had to remove it when transporting my bike on the back of my car. Items in the Tailfin stayed dry in heavy storms. Convenient zipper.

Perfect Bags

I got my Tailfin Aeropack, Frame bag and top tube bag, and love everything about them - the build, the look, and how they perform. Pretty much ideal setup for light bikepacking.

The 4.5L Frame bag fits perfectly to my bike, as well as 1.1 Top tube bag, that I fit with the same straps and is solid - in case someone also has the same bike and size.

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.
