FAQs

I am a small rider, will this fit my bike better than the standard 18L CargoPack?

Yes, due to the smaller profile of the SpeedPack and the adjustability of the seatpost connectors, this bag should fit any bike.

I already have a Rack or CargoPack (formerly known as AeroPack), can I purchase just the SpeedPack top bag and fit that to my existing Rack/CargoPack?

No, the SpeedPack has a different mounting connector kit. You can buy the SpeedPack Top Bag + connector kit here, which will fit your current Rack or CargoPack setup.

My bike is full suspension/has a dropper post. Is the SpeedPack the best choice for me?

Vs the CargoPack, the SpeedPack will fit best on full suspension/bikes with dropper posts. This is not to say the CargoPack won’t fit, but you may be compromised on space and range of movement under/behind the saddle.

Can I fit my rear light to it?

Yes, the SpeedPack is compatible with both the Adjustable Light mount and Fixed light mounts. To fit the adjustable version, it must be mounted facing the reverse direction. Remove the base, rotate it 180º, and re-mount it facing towards the rear of the bag.

I have a rack. Is the SpeedPack compatible with it?

The SpeedPack will be available as a removable version from January 2026. Sign-up to our mailing list to receive updates.

Is it waterproof?

The main compartment is 100% waterproof.

What are the differences with the connector parts to the original bag?

The front connector hardware has a 4-point attachment plate to the carbon internal frame. It comes with 3 different lengths of FitLink connectors 30, 60 and 90mm in length which are all adjustable up to +/- 50º of vertical alignment. The hardware at the rear is similar to the original, just 10mm lower and a slightly different profile, giving improved stability.

What is the 3L mesh pocket for?

The wrap-around 3L mesh pocket of the SpeedPack is for items that you may want to be readily accessible or that are not impacted by the weather. For example, the mesh pocket could be used to keep a rain jacket or some extra food. It comes with a drawstring cinch to ensure the opening of the pocket can be cinched tight to ensure items are not lost.

Can I purchase spare parts for my SpeedPack?

Yes, all spares are available on the Spares Page.

Is the SpeedPack lighter than the 18L CargoPack?

Yes, it weights 350g (bag only) and 700g when mounted on a Carbon Arch without pannier mounts. It is ~40% lighter than the current CargoPack.

What is the max weight limit for the SpeedPack?

The maximum weight limit you can carry in the SpeedPack is 8kg (road) and 4kg (off-road).

Can I use my panniers alongside the SpeedPack?

Yes, if you already have pannier mounts on your arch, you can use them with the SpeedPack mounted.

What material is the internal frame made of?

The SpeedPack’s internal frame is made of carbon to ensure lightness without compromising strength.
