Apidura Racing Top Tube Pack - 0.5 L
The Apidura Racing Top Tube Pack is a lightweight, streamlined strap-on top tube bag for ultra-distance competition, gravel racing and time-conscious riders. Available in 0.5 L (75 g) and 1 L (105 g), both 4.5 cm wide, it has a magnetic one-handed flip-top opening, a protected cable port and seam-welded Hexalon construction.
Why a top tube bag – and why this one
Reaching into a jersey pocket or stopping to open a saddle pack costs time in a race. A top tube pack keeps snacks and small essentials right in front of you. The Racing Top Tube Pack is built so that this access is fast and the bag stays out of your way:
- It opens with one hand. A reinforced structure allows a magnetic flip-top with full-length access – easy to open on the go and just as simple to keep the contents dry.
- It protects bike and belongings. Closed-cell foam padding protects both the frame and what is inside.
- It keeps devices charged. A protected cable port enables device charging while you ride.
- It does not get in the way. The slim 4.5 cm wide design maximises storage space without interfering with your knees, and the pack is compatible with a wide range of frame bags.
- It is light. Hexalon, an ultralight waterproof laminate developed for Apidura, keeps the weight to 75 g (0.5 L) or 105 g (1 L).
Who is it for?
- Ultra-distance and gravel racers who want snacks and essentials within one-handed reach.
- Road and gravel riders whose bikes have no top tube bosses – the pack mounts with straps.
- Bikepackers using a frame bag who need a top tube pack that works alongside it.
Which size? The 0.5 L (75 g) is the lightest option for a few small items; the 1 L (105 g) gives more room for essentials. Compare the dimension drawings below with the space behind your stem.

Frequently asked questions
Will the Racing Top Tube Pack fit my bike?
In most cases, yes – Apidura's strap-on top tube packs are designed to fit the vast majority of bikes with standard, oval or oversized top tubes. On smaller frames, check the length of the pack against the space behind your stem (see the dimension drawings above).
Does it need top tube bolts?
No. It mounts with two Hypalon-reinforced Velcro straps around the top tube and one around the steerer, without tools. If your frame has top tube bosses, the Racing Bolt-On Top Tube Pack is the bolt-on alternative.
Can I fit a phone in it?
Most of Apidura's top tube packs fit standard-sized phones. Check your phone's measurements against the dimension drawing of the size you choose.
Can I charge a device from it?
Yes. A protected cable port lets you run a charging cable to a device while you ride.
