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)

Recommended for MTB and Gravel bikes

Removable: Quick Access

Bag removes from rack. Perfect for groceries, cafe stops, and commutes

Recommended for Road and Touring bikes

Guide to Top Stay Length

Which Top Stay is right for me?

XS to L Bike Size (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)

XL+ Bike Size (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

Top Stay Specifications

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

What are Pannier Mounts?

Pannier Mounts let you attach side bags for extra carrying capacity. As they’re built into the rack at the point of manufacture, they can’t be added later – so you need to decide now. Most riders get them for flexibility, even if not using panniers straight away.

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?

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

Light and Mount Bundles

Pannier Accessories

Laptop Holster

What is a Laptop Holster? A protective support attachment for Tailfin Panniers, to keep your laptop secure and protected from impacts. Includes a zippered pocket for small items. 16L holster fits a 14″ laptop / 22L holster fits a 16″ laptop

How does it work? The holster suspends your laptop within the pannier, creating a protective gap at the bottom. If dropped, the bag absorbs the impact before your laptop is damaged.

Shoulder Strap

What is the shoulder strap? A strong padded strap for carrying panniers. Attaches via G-hook clips.

What’s great about it? Seamless foam padding won’t dig into your shoulder. Fully adjustable and reversible – wear it either way. Stays tidy when shortened, won’t flap around. Heavy-duty G-hook clip for secure attachment.

Clip-on Rear Light

What is the wearable light? Compact rechargeable safety light that clips onto Panniers.

What’s great about it? Clips directly onto pannier straps or bags for instant visibility. Six lighting modes with 35-lumen COB LED. USB rechargeable with a low battery indicator. Perfect for commuting or bikepacking.
