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.
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)
Thru Axle 12x142mm 1.5mm Pitch
Thru Axle 12x142mm 1.75mm Pitch
RAT Systems (RAT Thru Axle 12x142mm), you will need to order a 1.5mm thru axle, along with this adaptor part.

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 fast release dropouts make 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 Third-Party 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 been using the tailfin X2 rack for 6 weeks now, 3 to 4 times a week, 75 km each.
conclusion: great product worth its price!
excellent concept, excellent finish, absolutely top in daily use! It is a relief in comparison to the back pack I used previously. I completely forget it during the ride: no wackling, no noise. good capacity, variable size, waterproof.
