The X Series is our do-it-all rack designed to work with the AeroPack Trunk and Side Bags.
What are the differences?
The models differ by material and weight:
X ONE = Carbon Arch + Carbon Top Stay
X TWO = Carbon Arch + Alloy Top Stay
X THREE = Alloy Arch + Alloy Top Stay
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.

The X Series is our do-it-all rack. It combines the best of both worlds: side and top-mounted bags. It’s also quick release and fits any bike.
The Tailfin X Series has been engineered to blend seamlessly with your bike. It is an evolution of the original T1 rack, winner of a prestigious Red Dot Design Award.
The rigid wishbone-shaped carbon or alloy frame offers exceptional agility, with no sway or rattle.
The X Series rack contains a top-mounting feature to accommodate the AeroPack Trunk.
Ingenious quick release design makes it simple for you to use one rack for all of your bikes or one bike for everything.
The rubber grip fits to any seat post (including deep aero) with no risk of damage.
The X Series boasts perfect geometry to avoid heel strike, and the ‘pack and go’ design avoids the need for awkward adjustments.
The twin top stay adds further functionality so you can attach lightweight gear
The X THREE features an alloy arch and alloy top stay for the most demanding types of riding
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
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.
With the 3rdParty Pannier Adaptors, it’s possible to fit different brands of bike bags to the X Series pannier rack.
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.
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)

I have searched for the best bike bag solution for daily rides and bike packing excursions on different bikes without having to buy multiple set ups. Tailfin was the answer I was looking for. My bags are extremely well built and I don’t feel them swinging on my bike when riding road, gravel or single track- locked on solid! and that is saying something! I love how easily the whole mechanism is to install and remove from my bike and the ability to quickly switch the bags from road to mountain bike. No need for multiple bag set ups. Customer service has been great and everything came complete in my shipment. 5 stars Tailfin!!
I have used my pannier and rack approximately 50 rides to and from work. There is no water getting in the pannier and the rack is pretty solid. The rack and pannier are both very sturdy in their mounting and very removable. I strongly recommend this product. My only reason for not giving the product 5 stars is that one of the rubber mount buffers fell off in the first use of the rack and since there is slight damage to the rack and the bag. I estimate the bag will break in about 3-4 years at the current usage rate (3-5 days/week commuting 12.5 miles each way).
