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.

Ultra Durable Pannier Side Bag
Having done several multi-day, self-supported races using top-tier, name-brand rear bags, I keep trying different solutions for storage (e.g., triangle bags) as I just hate the back-and-forth sway that comes when using a rear bag no matter how tightly or effectively you pack it or pull it tight to the seat post. The Tailfin is a simple and surprising light answer to this issue effectively locking the bag down so that it doesn't interfere with your riding, especially when out of the saddle. I thus highly recommend the Tailfin with full confidence. Only (non-related) issue for me now is selling all the rear bags I've collected over the years but will never use again.
Its cool, its aero, its easy, its versatile, its black, its lightweight, its large, its awesome
I bought the X-series THREE with two SL Panniers. After trying to fit camping gear and clothes into a number of distributed bike packing bags on my road bike and eventually giving up, putting the same gear into the SL Panniers was a breeze, and very easy to access. I haven't had a chance to go camping yet, but did go on a 60km test run including some gravel and they were solid. Obviously it felt a bit rear-heavy (had 7kg+ of gear) and didn't get a chance to try on any serious climbs but felt stable out of the saddle. It would be good if Tailfin could also work on a front handlebar bag for road-bikes, something easy to attach/detach, stable, and not getting in the way of hand-positions and levers.
A couple of minor negatives: instructions for the rack assembly were not the clearest: the lockings are loose and don't seem to lock in position, and the small plastic insert from one of the dropouts was missing, which left it rattling until I substituted a small rubber earbud instead.
