Custom Bike Frame Bag: From Frame to Bag

A custom bike frame bag starts with the bike itself. Instead of forcing a standard-sized bag into an imperfect space, the frame is measured first so the final bag can follow the geometry of the bicycle. 

In this SPRAK FIELD NOTE, we take you through the process of creating a custom bike frame bag—from measuring the frame and developing the pattern to cutting technical fabric, sewing the panels and fitting the finished bag onto the bike.

The result is a purpose-built storage system designed around the rider, the bicycle and the way it will be used. For bikepacking and lightweight adventure riding, every part matters: fit, material, construction, access and durability.
