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. For bikes without bolt-on bosses, see our Expedition Top Tube Pack

"The top tube pack is the place for things that I don't want to be rummaging for. I never wear jerseys with pockets, so even on day rides I prefer to use this pack to store essentials."

- Jenny Tough / Human-Powered Adventurer

EXPEDITION SERIES

Created for road riding and long-distance tours, the Expedition Series is built from a lightweight material that provides unparalleled waterproofing and defence from the most punishing conditions.

SPECIFICATIONS

Materials

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.

Care Instructions

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.

APIDURA

We’re an independent, family-run business of cyclists, makers and problem solvers, brought together by a shared mission to find better ways to explore the world by bike.

Apidura was born from necessity; pioneering ultralight, rackless packing systems to help us take our love of cycling further and allow riders to unlock their instinct for adventure. As devoted adventure cyclists, we design with our fellow riders in mind, creating products that address genuine needs and bring new value to the bikepacking scene. We create the best packs we can, using technical materials and precision crafting techniques – and when we find a way to improve them we do so straight away and without fanfare. We don’t do ‘seasons’, limited editions or discount our gear – we simply create the best possible technical bikepacking gear that’s built to last.
