Frequently Asked Questions

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.

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.
