Frequently Asked Questions

Product Overview

Any X series product allows you to carry both side and top bags. Any S series product is for carrying top bags only

The AeroPack S & X are a bag and rack which are permanently joined together. It’s designed to be a direct replacement to a seat pack. The AeroPack Trunk has the same 20L roll-top bag but can be easily attached or removed from any of our racks.

We have 3 types of X Series pannier rack to give the ultimate choice. The difference is between weight, material and aesthetics:

WEIGHT & MATERIAL DIFFERENCES

X ONE – Carbon arch and carbon top stay (330g*)

X TWO – Carbon arch and alloy top stay (370g*)

X THREE – Alloy arch and alloy top stay (480g*)

AESTHETIC DIFFERENCES (shape)

The carbon arches of the X ONE and TWO differ to the X THREE, as we are able to create more subtle shapes when working with carbon. The Alloy arch of the X THREE is one of a more rudimentary design.

*weights shown are for frame mounting only, for weights including quick-release dropouts and axles add 60g

We have 3 types of S Series Trunk Rack to give the ultimate choice. The difference is between weight, material, and aesthetics:

WEIGHT & MATERIAL DIFFERENCES

S ONE – Carbon arch and carbon top stay (270g*)

S TWO – Carbon arch and alloy top stay (310g*)

S THREE – Alloy arch and alloy top stay (420g*)

AESTHETIC DIFFERENCES (shape)

The carbon arches of the S ONE and TWO differ to the S THREE, as we are able to create more subtle shapes when working with carbon. The Alloy arch of the S THREE is one of a more rudimentary design.

Help Me Choose

Answer the questions set out below to find the right Tailfin products for you.

  • Side panniers allow you to carry more gear without having to install a frame bag or bar bag
  • You can use our Tailfin side panniers (our range will grow in the coming years) or buy the boosters (in development) to carry other brands of panniers

If yes, the X Series racks or the AeroPack X will be the right choice for you.

If no, the S Series racks or the AeroPack S will be the right choice for you.

  • It will be around 20 seconds faster to remove the AeroPack Trunk Top Bag from the bike, and it will be easier to carry (good for commuting, quick cafe stops etc)
  • The full integrated AeroPack Carbon and Alloy S & X are lighter than the Rack + AeroPack Trunk Top Bags in the X & S Series
  • If you have an X or S Series rack you are able to carry gear on top of the rack, when the AeroPack Trunk Top Bag is not present.

If yes, the X Series Pannier Racks or S Series Trunk Racks with the detachable AeroPack Trunk Top Bag is the right choice for you.

You can buy these together as a set, from the X Series Rack & Bag page, or S Series Rack & Bag page.

If no, it is not important for you, then either the AeroPack X or AeroPack S will be the right choice for your needs.

If important to you, then you will need to select the Carbon version of our Racks (X ONE, X TWO, S ONE, S TWO) or Rigid Seat Packs (AeroPack Carbon X or AeroPack Carbon S)

If not important to you, then you can select either one of the Alloy Racks (X THREE or S THREE) or Rigid Seat Packs (AeroPack Alloy X or AeroPack Alloy S)

Thru Axles

If you’re unsure of the Thru-Axle you require please check out this page. If your bike isn’t listed in the table, or you’re still unsure, just email us through at support@tailfin.cc with your bike make, model and year, and we can assist.

If you’re unsure of the axle type of your bike, see our blog post here.

Racks

Every rack is provided with an extra-long aero seat post connector. Please be aware though, that the seat post connector may rub the carbon finish over time, so we suggest placing some soft material in between the two parts if you wish to retain the original finish of your post.

If your rack develops a fault, please email us at support@tailfin.cc with as much detail as possible (including photos) of the issue.

At this time it is not possible to mount 3rd party panniers to our X Series racks. We are developing the ‘boosters’ (adaptors) to allow this, and they are likely to be ready towards the end of the year. If you subscribe to our email list, we will inform all of our subscribers once they are ready.

Yes, our racks have a large tyre clearance and so should work with most mudguards. Tyre clearances:

26″ – Up to 4″/100mm
27.5″ – Up to 3.5″/85mm
29″ – Up to 3″ /75mm

Top Bags & Side Panniers

Each bag has a load capacity of 9kg, so all three bags (Top and Side) the rack will carry a total of 27kg.

The differences between the two side bags are subtle; they are both ultrasonically welded, 100% waterproof, and same 22-litres capacity.

The distinction that can be seen is that the Super Light (SL) bag is one of the lightest panniers on the market weighing in at 650 grams, and is designed for those who want to save grams and travel fast – whether that be commuting or touring.

The Ultra-Durable (UD) is the more robust of the two, constructed with thicker, tougher walls. It’s hypalon construction means it will stand up to more of a rough ride and is suited to those who expect their bags to take a pounding. The UD also features a waterproof external pocket, and weighs in at 800g.

Fundamentally, SL is about speed and the UD is about durability.

Yes. Every bag comes with spacers that allow it to fit racks with 8, 10 and 12mm diameter tubing.

We don’t recommend using the bag if the clamp is defective. If your clamps become damaged, go to our Returns Page here and fill in our repair form to arrange a spare part, or repair.

If there is a small hole in the bag and you’re on the road, we recommend using a high-quality repair kit or heavy-duty sealing and repair tape (e.g McNett Tenacious). For longer-term, reliable fixes though we always recommend you arrange a repair with us. Contact us at support@tailfin.cc for help with this.

If any of your bags develop a fault, please email us at support@tailfin.cc with as much detail as possible (including photos) of the issue.

Compatibility

Yes you can, so long as the axle on your other bikes is the same, you can simply swap between using the QR attachment. If it isn’t you’ll need a new axle to make it compatible. It’s a good idea to buy a new axle for each bike anyway, just for ease of changing between them. All of our axles can be found here.

Unfortunately, we’re still working on this technology. We hope to be completely compatible by the end of the year, subscribe to our email list to stay posted on this.

Yes, all our axles fit both bikes with rim and disc brakes.

Yes! Every Rack and Rigid Seat Pack ships with spacers and screws so you can affix it directly to your frame (rather than to one of our axles). The outer width between mounting points can vary which is why we include spacers and screws so you can avoid overly flexing the rack.
