Apidura Expedition Full Frame Pack vs Rockgeist Half Frame Bag
Two frame bags, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Rockgeist Half Frame Bag is ahead on how many frames it fits, weight and price. Nothing measured here goes the other way.
Assembled from the differences below rather than written over them. Every figure is a published measurement or computed from one — nobody here has used either one.

Frames it fits
10 percentage points, 33 more frame sizes for the Half Frame BagChecked against every current bike size we hold published geometry for, using the maker's stated minimum seat tube and top tube plus front-triangle area so sloping frames are not wrongly excluded. No bag maker can publish this, because they do not hold the frame data.
Weight
140g lighter on the Half Frame BagEmpty weight as published. Worth holding against capacity rather than alone — the lighter bag is not the better one if it carries a third less.
Price
