APIDURA Expedition Bolt-On Top Tube Pack (1L) | Fully waterproof top tube bag supporting everything from daily rides to touring

This bolt-on top tube bag attaches directly to the top tube bosses. With a highly durable and fully waterproof construction, it's suitable for everything from commuting to bike-packing.

Do you need quick access to snacks, your smartphone, or a mobile battery while riding? The APIDURA Expedition Bolt-On Top Tube Pack (1L) is designed to meet that need.

By adopting a bolt-on system that attaches directly to the top tube bosses, it significantly reduces side-to-side sway compared to strap-on types. This results in a clean fit and high stability.

The main body uses APIDURA's unique "Expedition Grade Fabric." Combining a fully waterproof RF welded construction with a waterproof zipper, it provides high waterproof performance even in sudden rain or prolonged bad weather.

With a capacity of 1L, it's a convenient size for storing smartphones, snacks, mobile batteries, and small tools. The interior is wipe-clean, making it suitable for storing food and gels.

The slim, tapered shape minimizes knee interference, while the HDPE reinforced construction ensures high stability. It fits a wide range of bikes, from road bikes and gravel bikes to touring bikes.

From daily commutes to multi-day adventure rides, this is a reliable top tube bag regardless of weather or road conditions.

The wipe-clean interior is also convenient, making it easy to keep food and gels clean. The stability provided by the bolt-on attachment is also high, and the bag sways minimally on rough roads or gravel, reducing stress while riding.
