The AeroPack Carbon X is our all-in-one integrated rigid seatpack, with side mounts for added versatility.
What are the differences?
The models differ by material and weight:
AeroPack Alloy X = Alloy Arch
AeroPack Carbon X = Carbon Arch
AeroPack Alloy S = Alloy Arch
AeroPack Carbon S = Carbon Arch
What are my mounting options?
An Axle including Quick Release Dropouts allows you to swap out your current axle for a Tailfin axle to mount the tailfin rack.
Frame mounting allows you to mount directly to the frame using screws.
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

The AeroPack X adds side mount features so you can take that little bit more.
Seat packs are great. The AeroPack X is awesome. The AeroPack X takes it to the next level. We take everything that you love about seat packs and pannier bags and combine them in to the ultimate way to carry your gear.
The side mounts on the AeroPack X arch allow you to attach various bags and accessories so you choose to take that little bit (or a lot) more.
The pack is constructed from a combination of Nylon and Hypalon laminates that are High Frequency welded to create a pack that is 100% waterproof.
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.
One of the key advantages of the AeroPack is the ability and ease of accessing your gear on your bike.

The Tailfin Axle Mount System means you can fit and remove the AeroPack in seconds.
A zipped pocket keep a few essentials handy.
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
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.
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)
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.
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.
