For the AeroPack - For riders with small frames or less than 100mm of exposed seatpost, we recommend using the AeroPack Extended Seat Post Connector. This replaces the standard connector and pushes the AeroPack back a further 50mm.

For X & S Racks - Unfortunately, the extended top stay is not yet available, but it is in development now and we hope will be ready to buy in June 2021.

The top bag itself is shaped in a 'wedge', and so like a traditional seat pack, you need to pack some smaller/softer items at the front, and larger items at the back. This will maximise the space available.

Yes! We genuinely believe “the best bike packing bike is the bike you already own” therefore it was important that all our rack / AeroPack systems could be used with full suspension bikes. Using a unique articulated design each pivot contains replaceable plain bushings which allow it to adjust position as the suspension compresses. They will also work with road and gravel bike suspension systems such as Trek’s IsoSpeed and Cannondale’s Kingpin Suspension.

Yes, the quick-release seatpost connector is compatible with all seat posts- including dropper, carbon, and aero. An extra-long seat post connector is included with all shipments for deep-aero seatposts.

All our racks come with 3 choices of mounting option:

  1. Axle + Fast Release Dropouts - we ship you a rear axle to swap out on your bike, the rack then affixes to this axle in seconds, allowing it to be mounted or removed in seconds.
  2. Frame Mounts + Fast-Release Dropouts - we ship you mounts which screw into the frame eyelets on your frame, the rack then affixes to this mount in seconds, allowing it to be mounted or removed in seconds.
  3. Frame Mounting - with this option, you screw the rack directly to your frame via the frame eyelets on your bike. This option is not fast-release, and will need to be unscrewed from frame when mounting or removing.

Yes, all Tailfin Racks and AeroPacks come with security screws that allow you to lock to your axle, or frame mounts, depending on your chosen mounting option.

Yes, but you will need to add the 3rd party pannier adaptors to your order

 
 

AeroPack FAQs

The AeroPack is an integrated seat pack, meaning that the top bag and arch are connected together. With the X Series Pannier Racks and S Series Trunk Racks, the top bag is detachable. For some riders this is an important difference, for others, it is not. The AeroPack is lighter for the weight-conscious rider and has a more simplistic design - which is sometimes preferential on longer trips.

Both alloy and carbon racks have been tested to the same standards and are capable of carrying a maximum of 27kg. The carbon-fibre AeroPack has been designed to be strong, and we have historically seen close-to-zero failures due to impact. The main differences between the Alloy and Carbon versions of the AeroPack are weight, price, and aesthetics.

The pack itself has loops made for certain clip-on lights. We also offer seatpost mounted light mounts, and regular rack mounted light mounts, which affixes to the AeroPack to allow you to mount your rear light directly to the pack.

Yes, the AeroPack can carry up to a 13" laptop, with the only limiting factor being the amount of available seatpost space. If your saddle is low then you will have less space available to fit the laptop and in this case, it may be best to use a side pannier instead. You can pack it vertically (providing there is space as mentioned), or horizontally. If packing vertically you'll want some items on either side of the laptop to keep it stable over any rough terrain.

This depends on the type of riding you’re doing now and your plans for the future. If the majority of your trips are short overnighters then you probably won’t need side panniers, likewise if you're riding mainly singletrack. If you’re planning some big adventures or want the option to carry up to 27kg in the future, then we recommend the pannier mounted model as you can attach Tailfin Panniers to increase capacity. With our Pannier Adaptors, you can also carry other brands of panniers.

Almost perfect

I had no problem with Tailifin product except only one thing. The bag opened on bumps with high speed, but I have fixed the issue, just connected both strips on the top of bag.
Bag has satisfying capacity. During rain a content is still dry. And finally the big plus for top opening.

Solid as a rock but light as a feather

Easy to build from the box, looks so elegant and well engineered. After first couple of uses was able to fit/remove very quickly. After reading other reviews I superglued the rubber inserts in and they seem secure. In use it’s so easy to pack with loads of room, easy access and the side zip makes it easy to expel all the air to give a neater bag when only half full. On the road and off road it just felt part of the bike and the was no rattle or sway at all. It also attracted many envious looks and comments from all the riders in my group. Even though I have a large frame and high saddle I went for the extension to give me more room. All in all it’s a brilliant piece of kit.

Tailfin Aeropack Alloy

If like me, you were looking for a large capacity seatpack that eliminates sway, then you have found the right option. You won’t know it’s there at all whilst riding, fit is loads of stuff (I managed to carry my tent, sleeping mat, toiletries and some cool weather clothes in there on my trip recently). And the fact it looks super sleek is just an added bonus.

I went for the alloy version as I’m not fast enough to worry too much about a tiny bit of extra weight, I also went for the frame-mounted with fast release dropouts. Set up is easy and taking it on and off the bike is a breeze. Which is lucky because I’d say the biggest negative is accessing the contents whilst it’s still on the bike…

There’s an additional “Extended Seatpost Connector” for £15 in the accessories page, it’d be nice if this came as standard with the bag. They say this is for people with small frames or low seats but I am 6”2 and have an XL frame bike and could still do with it to be honest. The design is tapered to sit under your saddle, like a regular seatpack, so only stuff at the side zip or the back of the pack are easily accessible. But by using this extender and moving the whole thing slightly away from the saddle, so your entire contents are accessible would make this product far superior.

I also went for the option without pannier mounts - they’ve never really been my style, if I need to carry any extra gear I’ll pick up a cargo cage. The support team told me if you a cargo cage attach using all 3 bolts you can carry up to an extra 4.5kg for road riding (a bit less for gravel/off-road). Which I found useful to know and I don’t think is written on the site anywhere.
