What are my mounting options?
Axle + Fast-Release Dropouts: We ship you a Tailfin Axle to swap out for your own, our Fast-Release Dropouts allow you to mount/dismount the rack from your bike in seconds.
Frame Mounts + Fast-Release Dropouts: We ship you Frame Mount Adaptors which attach to your bike’s frame mounts, our Fast-Release Dropouts allow you to mount/dismount the rack from your bike in seconds.
Frame Mounting: You screw the rack directly onto your frame mounts, without a fast-releasing mechanism.
Which Axle do I need?
If you need help figuring out which axle type to use, please use our guide posted here as a reference.
Most Bikes Use a Quick-release Axle (Pictured above-right)
Use the guide below ONLY if your bike uses a Thru-Axle. If you’re unsure – see above.
Thru Axle 12x142mm 1.0mm Pitch
*for Open frames you will need an axle cap also, found HERE
Thru Axle 12x142mm 1.0mm Pitch – Speed Release (this is a double lead axle)

This is it: the ultimate minimalist rigid seat pack system. Aimed at the performance cyclist who wants to go fast either on or off-road, it is an integrated top bag with no side pannier mounts.
Seat packs are great. The AeroPack is awesome. We take everything that you love about seat packs and pannier bags and combine them to create the ultimate way to carry your gear.
Don’t let your gear slow you down. The AeroPack is designed for aero advantage, and the stiff, rigid frame keeps your ride smooth and free from tailwag.
Watch the deep dive video and get hands on with each and every component. See the modularity, hear the satisfying clicks as components move together and get a feel for the overall size.
The rigid parabolic carbon arch connects solidly to the AeroPack bag with 6061-T6 aluminium pivot system.
The pinnacle of ultra distance racing is the Transcontinental Race. Used in both TCRNo6 and TCRNo7, the AeroPack has seen some serious miles and excelled in arduous real-world testing.
The seatpost connector is kind to carbon and designed to wrap around any size seatpost from 25mm through to a 3″ deep aero. So no matter what bike you ride, you can securely attach and quickly release the AeroPack.
With the AeroPack light mount it enables you to fit any seatpost light to the back of the AeroPack for maximum visibility.
The AeroPack makes it easy to access your gear on the bike thanks to a roll-top opening and direct access pocket.
The Tailfin Axle Mount System means you can fit and remove the AeroPack in seconds.
The wide mouth, top opening design means you spend less time packing your gear. The time you spend moving is as important as the time you spend stopped.
The AeroPack X rack will fit nearly all tyre sizes:
26″ – Up to 4″/100mm
27.5″ – Up to 3.5″/85mm
29″ – Up to 3″ /75mm
The AeroPack is rigid and light, meaning no tailwag and a smooth, stable ride. It’s almost like you weren’t carrying any gear at all.
Replace your axle with a Tailfin axle to mount the Tailfin rack. Most bicycles use a quick-release axle, however, we also support the new Thru Axle standards (e.g. 12×142, 12×148, E-Thru, Syntace X-12, etc)
One of the challenges with any roll top bag is the speed with which you can enter the main body of the bag. The direct access pocket allows you to get in to the main body of the bag without opening the roll top.
High performance laminate and high frequency welded seams make the AeroPack completely waterproof.
It’s now possible to attach our racks directly to frames with eyelets. The quick-release rack dropouts are modular so you can choose to use them, or not.
A zipped pocket keep a few essentials handy.
The Frame Mount Adaptor set allows you to mount directly to your frame mounts but still keep the Fast Release Dropouts for easy on and off rack mounting.
The AeroPack seat post connector gives a little more breathing room behind the seatpost. Great for those with smaller frames.

Delivery from UK to Belgium went pretty fast. I watched the installation video on Youtube and could install the rigid pack very quickly and easy. I made some trips with it and I'm really happy untill now. You barely feel the rack, no sway at all, easy installation and removal. I hope the durability will be ok for the next years because it's an expensive investment. When you like bikepacking or long distance trips and you're looking for a very good product, don't look further and buy this.
The design of the bag, frame and mounting mechanism is very impressive. The construction was very precise and I had the Tailfin AeroPack constructed and mounted to my bike with no difficulty.
