Apidura Racing Bolt-On Top Tube Pack – 1L
The Apidura Racing Bolt-On Top Tube Pack is a lightweight, streamlined 1 L top tube bag that bolts directly to top tube bosses, built for ultra-distance competition, gravel racing and time-conscious riders. It weighs 100 g and is 4.5 cm wide, with a magnetic one-handed flip-top opening, a protected cable port and seam-welded Hexalon construction.
Why a bolt-on top tube bag – and why this one
When every minute counts, food, electrolytes and small essentials need to be reachable without stopping – and without a bag that shifts on the frame or rubs your knees. The Racing Bolt-On Top Tube Pack is designed around exactly that:
- It is fixed to the frame. Two tool-free bolts attach it to the top tube bosses, and a Hypalon-reinforced Velcro strap secures it to the steerer. Multiple bolt positions let you place it where it suits your bike.
- It opens with one hand. A reinforced structure allows a magnetic flip-top with full-length access, so contents are easy to reach on the go and just as simple to keep dry.
- It protects what is inside. A removable, closed-cell foam padded base protects both your frame and your electronics.
- It keeps devices charged. A protected cable port enables device charging while you ride.
- It stays out of the way. The slim-line, 4.5 cm wide design avoids knee rub, and the bolt-on attachment is compatible with a wide range of frame bags.
Who is it for?
- Ultra-distance and gravel racers who want quick, one-handed access to snacks and essentials.
- Riders with top tube bosses who prefer a clean, strap-free fit on the top tube.
- Bikepackers using a frame bag who need a top tube pack that works alongside it.

Frequently asked questions
Will the Racing Bolt-On Top Tube Pack fit my bike?
It fits bikes with top tube accessory mounts (bosses). The variable mounting positions give a universal fit across these bikes, including the BMC URS. On smaller frames, check the length of the pack against the space available (see the dimension drawing above). For bikes without bosses, the Racing Top Tube Pack is the strap-on alternative.
How is it mounted?
Two tool-free bolts attach the pack directly to the top tube bosses for a clean, strap-free fit along the tube, and one Hypalon-reinforced Velcro strap secures the front to the steerer.
Can I use it together with a frame bag?
Yes. The bolt-on attachment is compatible with a wide range of frame bags.
Can I charge a device from it?
Yes. A protected cable port lets you run a charging cable to a device while you ride, and the removable padded base protects your electronics inside.
