Best in class fit
A custom fit from a production product? Nine sizes, adaptive geometry and our Frame Bag Sizing Tool make this a reality.
3D welded construction – Minimise knee rub
Unique 3D tapered pack shape mapped around pedalling movement. Maximise pack volume, minimise leg rub.
Wedge or Half Frame Bag: you decide
Wedge shaped packs prioritise water capacity and allow for larger bottle placement at the rear. Half frame bags allow for maximum kit storage.
Durable zip with one handed functionality
Internal carbon support structure reduce the chances of a zip bursting by supporting it, minimising pressure from content bulging and keeping it perfectly aligned. This also makes opening the pack a one-handed operation: even without a rear strap.
Adaptive geometry
Conformity zones at the front and rear of the Frame Bag allow it to adapt to the unique geometry of your frame.

Media Reviews
"Its innovative space frame technology, user-friendly functionality, zipper support, stable and secure fit and overall aesthetics make it the best frame bag I’ve ever used."
""I’ve been impressed with the half-frame bag’s stability while riding. It only utilizes four attachment points – with nothing on the seat or head tubes – and it’s held up great on even some long rides I’ve gone on recently where I’ve packed it full of food and extra clothing."
"The Tailfin Frame Bag is a new benchmark for frame bags. It is well thought-out, practical and highly functional."
10/10 - "Strong, durable and impeccable in use with sizing to suit a wide range of bikes."

I purchased for a hardtail I was using for bike packing, but I changed my mind on that set up. I was so impressed with the overall design I decided to keep it for my gravel bike instead. Looks, fits and performs perfectly.
Frame Bags
Ich habe lange nach passenden Taschen für mein Gravelbike gesucht.
Die ich hatte, waren gut aber, die waren nie so fest wie die Tailfin.
Klettverschluss ist einfach und schnell aber jedoch gleichzeitig störend.
Beim Gravelbike muss man öfter Mals im Gelände absteigen und wieder drauf, dabei habe ich zwei meine Radhosen eher kaputt gemacht.
Die Kombination von Oberrohrtasche und Unterrohrtasche wie Tailfin gibt es wo anders nicht.
Die Taschen mit dem Haltesystem ist wirklich perfekt.
Die sind teuer, aber wirklich 1a.

The Tailfin Frame Bag range will work with all brands of top tube bag. We have positioned the V-Mounts to match those on our range of Top Tube Bags so you can share straps for a much neater setup.
Our Wedge Frame Bags are designed for you to prioritise water capacity so depending on frame size you should be able to fit a 1-litre bottle. You can also fit a Tailfin Bottle Dropper to increase the space for your bottles and therefore potentially increasing the size of bottle that will work in your frame. Finally we recommend the use of side-loading bottle cages. These ease access to larger bottles when used in smaller frames or with larger frame bags.
We use highly waterproof Hypalon and Ripstop Nylon materials and employ a welded construction technique to ensure zero water ingress. Custom water-resistant zips with protective zip garages prevent almost all water from getting in when the zip is fully closed, and the puller is in the garage; however, in the heaviest downpour, we cannot guarantee they won't let water in. We recommend keeping your electronics in ziplock bags.
We used 20mm diameter balls with a known mass per litre. Packed the bags out nicely then weighed the balls.
Yes, all Tailfin Frame Bags will fit a variety of different battery packs. A cable port at the front will also allow you to charge your tech on the go.
Ideally you would opt for the frame bag that fits each frame exactly however this may be unrealistic considering how many bikes you may have. In this case opt for the frame bag that allows you to fit the most frames well whilst also allowing for the capacity to carry everything you want. Use our Frame Bag sizing tool to find the best fit.
This first range is aimed at drop handlebar bikes (road and gravel) However you can still use our Frame Bag sizing tool to see if any will fit your full suspension mountain bike. If you have a hardtail or rigid MTB you may find you have a few options.
Firstly try not to over fill the pack or put any undue strain on the zip whilst riding. We also recommending cleaning the bag in warm soapy water after particularly muddy or gritty riding. Focus on the zip to ensure that no mud is clogging the teeth. Dry thoroughly and apply a dedicated zip lubricant in order to keep the zip running perfectly.
Only in the largest frame bags will you be able to fit a frame pump. There are storage straps for carrying a mini pump in every size though.
The complete Frame Bag range is compatible with any bottle cage. If you want to maximise bottle access or capacity then we recommend choosing side-access bottle cages.
It really comes down to personal preference and the space available within your frame. See our blog here for an in-depth look.
