Product Comparisons
Tailfin Pannier Racks are a stand-alone rack, with the option to mount a removable CargoPack or SpeedPack Rack Top Bag and Side Panniers. The Pannier Racks come in Carbon or Alloy.
The CargoPack is an 18L fixed system in either Carbon or Alloy. This can be chosen with or without Pannier Mounts.
The SpeedPack is a 10L fixed system in either Carbon or Alloy. This can be chosen with or without Pannier Mounts and includes 3 lengths of ‘fitlink’ connectors to make the SpeedPack angle-adjustable at the seatpost connector for best fit with your bike(s).
The CargoPack (formerly known as the AeroPack), and SpeedPack Systems comprise a bag and a rack which are permanently fixed together. They are designed to be a direct replacement for a seat pack.
The Rack comprises of an Arch and Topstay, which you can add a removable CargoPack Top Bag / SpeedPack Top Bag to.
We have a useful blog here that outlines the differences between our Rear Systems and Racks and reasons why you may choose one over the other.
The simple answer is the material! Carbon Racks have a carbon fibre Arch and Top Stay, whilst the Alloy Racks have an aluminium alloy Arch and Top Stay. The difference is therefore between weight and aesthetics.
We have a comparison guide for the material differences.
Weight & Material Differences
If you’re conscious of keeping your kit as light as possible, then we’d recommend the Carbon for you, as it is lighter than the Alloy version.
The Alloy is heavier, but the alloy Journey Rack is rated to carry up to 32kg – more than the Carbon Rack.
Aesthetic Differences
The Carbon Arches differ from the Alloy Arches, as we are able to create more subtle shapes when working with carbon. The Alloy arch is a more rudimentary design; however, the Journey Rack arch is different again.
Bar Bag System: This system comprises a Bag that fits a mount on your bars. There are 4 bag options available (Large and Small for Drop Bars and Flat Bars). The Bar Bags are bikepacking specific.
Bar Cage System: This system comprises a Cage fitted to a mount on your bars. There is the option to add one or all three Tailfin Bar Cage Bags, but you are free to use your own bag on the cage. The bags are secured using the Tailfin Cargo Straps. You can also carry other items using the cage, not just a bag, making it not bikepacking specific, and it is a more budget-friendly option.
Both systems offer specific accessories for mounting lights, GPS and GoPros to your Bar Bag Mount or Bar Cage.
We have 4 sizes of panniers.
Mini Panniers 5L/10L: These mini panniers are ideal for more minimal bikepacking, being low profile and can also be converted to Fork Packs.
Panniers 16L/22L: These larger panniers are perfect for longer bikepacking/bike touring, but also commuting, and have the option to fit a Laptop Holster and Shoulder Strap as additional items. They also feature an air valve for easier compression.
Product Specifics
Yes, you can see our full selection of spares on our Spares Page.
If you can not find the required parts, please email us at hello@tailfin.cc
CargoPack: 18L top-opening waterproof bag, with 2 x mesh pockets on the sides (each pocket allows 1.5L of space). 1 TPU strap over the middle, and the bag can be clipped closed in the centre or down the ends.
SpeedPack: 10L rear-opening waterproof bag, with 1 x 3L mesh pocket around the outside. Can be closed like a standard dry bag or down the sides with our T-Hook straps.
These bags are compatible with our Fixed and Removable Rear Systems, as the bags stay the same, but just the connector parts are what differ between the systems.
The maximum weight all axles can carry is 32kg.
Yes! Each Bar Bag uses the same mount across all sizes/styles. The attachment hardware for them is all the same, too. The spacers in the middle are for narrower (drop) handlebars, and you can remove them to fit wider (MTB) handlebars.

Pannier Bags allow you to carry more gear on your Pannier Racks and Rear Systems.
You can use our range of Panniers on any of our systems with pannier mounts or on the Journey Rack top deck. You can also purchase Third-Party Pannier Adaptors to fit carry other brands of panniers which fit on our pannier mounts. These are required if using third-party panniers with items on the top deck of the Journey Rack.
If yes, then you will want to select the ‘Removable’ Rear Systems option (or Journey Rack). The advantage of this is that you can remove the Rack Top Bag from the bike while the rack remains in place.
We have a Complete Guide to the Rear Systems, which outlines the key differences of all our Rear Systems.
If weight is important to you, then you will need to select the Carbon Rear System.
If weight is not a priority for you, and you want a more budget-friendly option, our Alloy Rear Systems are the ones to choose.
If you are racing ultras, you are going to want the lightest setup possible. We recommend our carbon SpeedPack paired with our Frame Bags and Top Tube Bags.
If you are bikepacking, you will want the CargoPack for gravel/mountain biking. You can add 5L/10L Mini Panniers and also Bar Bag/Cage Systems, Frame Bags, Top Tube Bags, Fork Packs and much more!
For longer-term touring, we recommend the Journey Rack with the Removable CargoPack, 16L/22L Panniers and Bar Bag/Cage Systems. We also recommend Frame Bags, Top Tube Bags, Fork Packs, and Downtube Packs, which are key items to have with you during your time on the road!
Compatibility
Yes, as long as you have the correct axle, or the axle on your other bikes is the same, you can simply swap the system between bikes in a matter of seconds. If the other bike uses a different axle, you’ll need a new axle to make it compatible. All of our axles can be found individually. Use our Axle Finder to choose the correct axle and adaptor (if needed) for your bike.
Yes, the Pannier Rack, CargoPack and SpeedPack use small plastic bushings at the connection points to pivot and work with your bike’s suspension. For full-sus MTBs, we recommend the Fixed Carbon CargoPack / SpeedPack over the Removable version, but for the Alloy, both the Fixed and Removable (Journey Rack) versions are both compatible with off-road and full-suspension bikes, too.
Yes, but you will need to add the R.A.T. Adaptor.
Yes! The only system that doesn’t include these as standard is the alloy Journey Rack, but these can be found as a spare.
We strongly recommend checking with your frame’s manufacturer before fitting, as there may be a weight limit on your bike’s rack mounts (some are only intended for mudguards/fenders).
We have 3 types of ‘UDH’ compatible adaptors. One is for the SRAM UDH itself, and the other 2 are for the SRAM T-Type Transmission derailleurs, which fit directly to a UDH-compatible frame.
For each of these, you will require a SRAM Adaptor. See below the adaptor you require, and also use our Axle Finder. For any additional help with compatibility, you can email us at hello@tailfin.cc
Axles
If you’re unsure of the Thru-Axle you require, please use our Axle Finder. If your bike isn’t listed in the table, or you’re still unsure, please email hello@Tailfin.cc with your bike make, model and year, and we’ll be happy to help.
If you’re unsure of the axle type of your bike, we have an axle blog.
You can purchase additional axles for different bikes. These are available on our Spares Page. So if you have one bike with disc brakes and one with rim brakes, you can add a separate QR Axle, Thru Axle or Universal Thru Axle, enabling you to switch your Rear Systems between bikes in seconds.
If your bikes all use the same thread pitch, then you can order just one axle. We have a useful Thru Axle Guide. If your bikes use different thread pitches, though, you will need to either order separate Thru Axles for each bike or one Universal Thru Axle.
The maximum weight the axles can carry is 32kg
If installed correctly, the Universal Thru Axle is just as strong as the Single Thru Axle.
Please see our PDF guides for Universal and Thru Axles or short video guides for how to fit your Axle.
No, our Axles are either QR or Thru Axles, so don’t fit the old style 10mm QR Thru Axle. 
No, our Thru Axles are only compatible with our Rear Systems and not other third-party racks.
The Universal Thru Axle is a 12mm Thru Axle that comes in 2-parts: 1x non-driveside and 4x driveside parts (1.0mm, 1.5mm, 1.75mm and SpeedRelease/Double Lead thread options).
We have a Complete Guide to the Universal Thru Axle available.
