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.

X Series Pannier Rack
AeroPack Trunk Top Bag
Superlight Pannier Side Bag
Ultra Durable Pannier Side Bag
super, light , easy to install, works great
I did it, I finally invested in the highest-quality rack and pannier for my gravel bike (Cannondale Slate). As a biologist and endurance athlete, I saw great potential for lugging my essential field gear (wetsuit, mask, snorkel) and sustenance into and out of my remote work locations in a unique and satisfying commute, or to do some overnight bikepacking. The rack installed beautifully. Great engineering and aesthetics. Between the two panniers and the trunk bag, I have an enormous amount of volume for all of my supplies to work, eat, and sleep. In these dark days of covid-19, I think its important for cyclists to do their part to social distance and not just stop into country stores, bakeries, or other businesses on long rides (if they are even open). Tailfin provides a high-quality, performance-minded way to carry everything you might need...and still feel fast, sleek, and stylish.
I’m impressed with the product. Easy to install and remove when needed. No sway, rock solid platform.
