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 1.5mm Pitch

AeroPack Trunk Top Bag
Ok lets gets the little quibble out the way , im short so my frame is small , i find that when the aero bag sits to close to the post so i cant open it fully or fill to its top as it catches on the saddle , unfortunately the extender does not fit the ridged rack (understand yourselves are working on this) I have solved this by using a third party bar extender for bike lights attached to the seat post, anyway apart from that its great , lovely flowing design and strong build , im not a fan of racks on bikes and usually use saddle bags which are very fiddley to attach but tailfin you have converted me , thank you. Oh yes the triple cage mounts are great which i use as extra bottle holders.
I ordered a tailfin and then Unfortunately realised That the quick release dropouts weren’t going to arrive in time for my trip. I requested to cancel my order as I needed a fast alternative. Tailfin were happy to oblige but offered some alternative fitment options as a constructive way to get me on the road with a tailfin. Although at the time I politely declined as these options didn’t work with my frame, a few beers with a friend later I had swapped his dropouts for Tailfin’s proposed direct to frame mount and tailfin had a another order from me. A personal service that secured an order, they even asked for photos of the trip. A smashing company and a perfectly simple product. If you’re considering a tailfin vs a saddle bag, that’s not even a question. The bag performed flawlessly for the entire trip, but tailfin, always room for improvement, those foldy down circlips, did someone else design them? They need to go, get some proper circlips on there or an e clip. I already have on mine. And please those glue those rubber grommets in on the quick release! Apart from that, I’ll be back for the the seatpost mount extender soon.
We just completed a 260 mile section of the Great Divide, both bikes had Tailfin racks, they performed flawlessly. the work great to synch down a 25L dry bag and water bottles on the side.
