Carbon or Alloy

Carbon

-Lighter option
-More expensive
-Maximum load: 27kg
-Material: Toray T700 carbon fibre

Carbon fibre offers exceptional strength to weight, meaning a lighter arch that is still capable of carrying the same load as our Alloy arches. If weight saving is a priority for you, then carbon fibre is the way to go.

Weights (without Pannier Mounts)
Carbon Rack: 317g
Carbon Integrated with bag: 700g – 922g depending on chosen bag type (SpeedPack/CargoPack)

Alloy

-Heavier option
-Cheaper
-Maximum load: 27kg
-Material: 6061-T6 Alloy

If you’re heading off-road, away from civilisation, then we’d recommend our Alloy options. Why? In worst case scenarios (dropping or crashing your bike) an Alloy Arch can withstand abuse a little better and can possibly be repaired or ridden when damaged – it will tend to bend. The Alloy options has additional triple bosses to attach accessories such as a Cage.

Weights (without Pannier Mounts)
Alloy Rack: 542g
Alloy Integrated with bag: 907 – 1129g depending on chosen bag type (SpeedPack/CargoPack)

Guide to Top Stay Length

Which Top Stay is right for me?

XL+ Top Stay (formerly ‘Short Top Stay’) – Use the below as a general guide:

with XL bike frame sizes (>58cm)
100mm or more visible seat post
no dropper post fitted to your bike
riders who want maximum aero benefits

XS to L Top Stay (formerly ‘Long Top Stay’) – For riders who feel they will need a little extra space behind the saddle when using the Removable Top Bag:

for smaller bike frame sizes (<58cm)
less than 100mm visible seat post
if you have a dropper post fitted to your bike
saddle positioned far back on its rails
if you plan to carry items on top of the bag (e.g sleep mat strapped to the bag)

Top Stay Specifications

Below shows the difference in real terms between the two sizes:

How will the Rack attach to my bike

Tailfin Axle Mount

Fit a Tailfin Rack by removing your bike’s axle and replacing with our Tailfin Axle. Watch how

Recommended for the strongest mounting method.

Frame Mount Adaptors

Fit Tailfin Frame Mount Adaptors to your bike’s pannier mounts.
Watch how

– Please check with your bike’s manufacturer that your frame is suitable for attaching a rack, as some frame mounts are used only for mudguards.

Whats the difference between our axles?

We supply 1 of these 3 axles with all of our rear racks. The axle you need will depend on your bike.

Single Thru Axle

Modern bikes use thru axles, select the single thru axle if you know your pitch thread.

Universal Thru Axle

Ships with multiple thru axles to fit all bikes

Quick Release Axle

Usually found on older bikes and are usually hollow with a lever on one side.

Packing Cubes

Stay Organised, Pack Smart

Avoid the dreaded ‘yard sale’ effect when emptying your things at the end of a day in the saddle. These Packing Cubes have been designed to simplify the packing process and to maximise the capacity inside Tailfin’s Rear Packs by incorporating clever shaping, thoughtful details, and high-performance fabrics.

With all three weighing less than 155g, we think that better organisation is worth the minor weight penalty.

Which Lightmount?

Cateye Wearable X Light

Clips onto loops in the CargoPack. (Not compatible with SpeedPack)

Adjustable Light mount (Seat Post Mimic)

Screws into the base of the SpeedPack and CargoPack. Allows seatpost-mounted lights to be attached.

16L Mini Pannier: Laptop Holster

Made of elastic and soft fabric, the Laptop Holster is designed to be used with a laptop case which will keep the laptop protected from the other contents of the bag. On the outside of the Laptop Holster is a useful zipped organiser pocket for everyday essentials.

The Laptop Holster effectively suspends a laptop within the bag, creating a gap between the laptop and the bottom of the bag, creating a false floor much like those found in high-end backpacks. If the pannier were to be dropped (or even placed down overenthusiastically), the structure of the pannier would hit the ground first and take some of the force out of the impact, ensuring the laptop doesn’t contact anything hard. Modular protection for up to 14-inch laptops, complete with zippered stash pocket.
