The X Series is our do-it-all rack designed to work with the AeroPack Trunk and Side Bags.
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.

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 X Series 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.
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)
