The AeroPack Carbon S is our all-in-one integrated rigid seatpack, with minimum weight and maximum aerodynamic advantages.
What are the differences?

AeroPack Alloy X = Alloy 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.

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.
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.
