Apidura says: 

A streamlined and secure space to store frequently used items on bikes with top tube bolt bosses.

A useful standalone bag for daily riding or as part of a larger bikepacking setup, the Expedition Bolt-On Top Tube Pack is a lightweight, secure storage space that’s ideal for stashing frequently used items on the road. The top tube bag is waterproof with welded seams and a pioneering waterproof zipper.

The bolt-on top tube bag fastens securely to the top tube bolt bosses common on gravel and adventure bikes, with a choice of mounting positions to accommodate every bike and frame size possible. A closed-cell foam padding structure protects your frame and electronics from damage and for added convenience, a protected cable port enables charging of devices on the go.

Opening and closing via an easy access one-finger zipper puller, the bolt-on top tube bag is a useful standalone bag for adventure cycling or as part of a full Expedition Series setup.

Our Verdict

Apidura Expedition bolt-on Top Tube pack 1L is a lightweight, waterproof and durable pack that bolts directly onto the top tube. It is sturdy and does not flop around whilst riding, even on uneven surfaces. The sleek shape keeps it narrow and doesn’t interfere with knees at the top of the pedal stroke. Accessing the pack is via the long zip than runs along the top edge, and the zip pull is easy to use even with gloves on. It is a perfect size for putting small items for easy access and electricals can be wired through the covered slot on the front edge.

Material & Construction

• The Expedition Bolt-On Top Tube Pack is cut from a three-layer laminate fabric that was developed specifically for Apidura. The material is lightweight, and is highly resistant to tears and abrasion. Notably, it’s welded together at the seams, creating a watertight seal that ensures the top tube bag remains completely waterproof.
• Two tool-free attachment bolts included.
• Wash the top tube bag by hand, using a mild diluted soap if necessary. Afterwards, let it air dry.
• Do not machine wash, machine dry, or iron.
• Excess strain can cause stress to the zipper mechanism and negate the waterproof nature of the closure. Do not overpack.
