Apidura Backcountry Top Tube Pack - 1 L
The Apidura Backcountry Top Tube Pack is a lightweight, durable and seam-welded waterproof 1 L top tube bag built for mountain biking and rough terrain. It weighs 115 g, is 4.5 cm wide, opens with a fully waterproof zipper, protects its contents with closed-cell foam padding and has a cable port for charging devices on the go.
Why a top tube bag – and why this one
On rough trails, anything in a jersey pocket bounces around, and stopping to open a saddle pack breaks the rhythm. A top tube pack keeps mid-ride essentials right in front of you. The Backcountry Top Tube Pack is built for the demands of off-road riding:
- It is made for rough terrain. Embossed nylon abrasion panels add durability, and closed-cell foam padding protects the contents on rougher rides.
- Contents stay dry and clean. RF-welded seams and a fully waterproof zipper keep out water and dirt.
- Easy access while riding. A one-finger zipper puller opens the pack on the go.
- Devices stay charged. A cable port lets you charge a GPS or phone from a power bank inside the pack, without sacrificing waterproofing.
- Your knees stay clear. The pack is designed to maximise storage space without getting in the way.
Who is it for?
- Mountain bikers who want snacks, tools and a phone within reach on weekend rides.
- Bikepackers and off-road racers who need a safe place for a power bank and cables as part of a touring setup.
- Gravel and trail riders who want a tough, waterproof top tube bag.

Frequently asked questions
Will the Backcountry Top Tube Pack fit my bike?
In most cases, yes – the straps fit standard, oval and oversized top tubes. On small frames, check the length of the pack against the space behind your stem (see the dimension drawing above).
How does it mount?
Without tools: two Hypalon-reinforced velcro straps go around the top tube and one around the steerer. No top tube bolts are needed.
Will my phone fit?
Most standard-sized phones fit. Compare the dimensions in the drawing above with your phone; for more space, choose the Backcountry Long Top Tube Pack.
Can I charge devices while riding?
Yes. A cable port lets you run a charging cable from a power bank inside the pack to your GPS or phone, without sacrificing waterproofing.
