“Tailfin’s AeroPack S is one of the best rear luggage options for serious bikepacking (and commuting) ever tested. It is expensive but its simplicity, ease of use and pleasing design make you forget the price within the first ride.”

Shake, Shake, Shake, IT DOES NOT

No booty shaking, tail wagging, bike swaying at all. The Tailfin aero pack distributes the weight so low and secure you barely feel it at all. You can even get out of the saddle with it on. Wether commuting or bike packing, this bag is a must have!

Thanks for these five stars, Matthew! Zero sway is exactly what we want you to experience so you can enjoy your ride instead! If you need any help in the future just let us know; [email protected]

Aeropack X Alloy - Love it!

I have recently purchased the Aeropack X seatpack, along with an SL22 pannier bag. I have used the system for commuting, as well as gravel bike touring over the past couple of months. I've done about 250km on gravel with zero issues, and I suppose over 1000km on road. The system does not rattle at all, and even with the pannier it is all super secure. You can load it up no problem, and it doesn't get in the way at all. I can take it off in seconds (Am using Thru axle mount) without hassle. Obviously when you have it all loaded you can feel the weight out the back, but that is all of the stuff I have put in it, not the Aeropack itself! In fact, I have found that if I am only carrying a change of clothes or similar I don't notice it at all, even to the point of getting close to my Strava PB's... Main thing is that if you do take it on and off is that I have found the rubber inserts that clamp around the Thru axle mount can come out easily, and can get lost. So just be careful there! Otherwise, it has done everything I had hoped it to be. Very happy!

Thanks for this, James! Great to hear you’ve been able to put everything to the test. We recommend applying a drop of superglue to the back of the rubber inserts if they come loose. Then clamp to your axle and leave to dry in place. All the best, Dan
