FAQ’s

Is the Rear Top Tube Bag waterproof?

We use highly waterproof Hypalon and Ripstop Nylon materials and employ a welded construction technique to ensure zero water ingress. Custom water-resistant zips with protective zip garages prevent almost all water from getting in when the zip is fully closed, and the puller is in the garage; however, in the heaviest downpour, we cannot guarantee they won’t let water in. We recommend keeping your electronics in ziplock bags.

I have an aero seatpost, will the Rear Top Tube Bag fit?

Yes, we supply 2 x 18.5cm Cargo straps and 1 x 14.5cm Cargo strap.

Do I need to strap the Rear Top Tube Bag to the seatpost?

We supply three straps to fit the bag, but we recommend you use at least two on the top tube, and if you are carrying heavy items, then you have the option to add the seatpost strap for added optional stability.

What capacity do the two options have?

0.8L for MTB and 0.9L for Road/Gravel

What is the minimum saddle height needed?

We recommend that your saddle is no lower than 150mm for 0.8l and 165mm for 0.9l, measured from the Top Tube to the base of the seat rails. Ensure that when using a dropper post, your saddle does not go lower than this.

Can I use the Rear Top Tube Bag with a dropper post?

Yes, the 0.8l MTB bag is designed to work with a dropper post; double-check the clearance against our specifications.

Will the Rear Top Tube Bag work if I am prone to leg rub?

The Rear Top Tube Bag is designed with a sleek profile that matches the contours of your seatpost and Top Tube. We advise that if you are not overfilling and using the correct style with the right bike type, you shouldn’t experience this issue. However, if you are unsure, we recommend using the Long Top Tube bag on its own.

Can I use the Rear Top Tube Bag with a Long Top Tube Bag?

Not the 3l and 2.2l, but they will fit with the 1.6l Long Top Tube Bag if you have more than 575mm of space on your Top Tube. Alternatively, they will work well with one of our short or standard-length Top Tube Bags.

Can I use the Rear Top Tube Bag with my Tailfin Frame Bag?

As we offer a wide range of Frame Bag sizes, it is challenging to provide a definitive yes or no answer. You can use our printable templates here and compare them against your frame to see if the mounts will align.

Are there spares that I can purchase?

Yes, V-Mount spare, spare straps and spare insoles are available here.

How can I keep the Rear Top Tube Bag clean?

Will the Rear Top Tube Bag bolt onto my frame?

No, they are not designed to be bolted and often bikes don’t come with rear top tube bolt mounts.

Is there a weight limit?

Within reason you can carry any weight in a Rear Top Tube Pack. The limit would be volume.

Can I fit a phone inside?

No, the pack is designed for tools and snacks; it is too small for a phone to safely fit inside
