Apidura Racing Saddle Pack 7L vs Ortlieb Saddle-Bag Two 4.1L
Two seat packs, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Racing Saddle Pack 7L takes capacity and weight; the Saddle-Bag Two 4.1L takes how far it reaches back, tire clearance, price and value per litre. Which of those you care about depends on the frame you are fitting it to.
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.
Where they differ
6 of the 6 things we can measure come out differently.
Capacity
2.9L more in the Racing Saddle Pack 7LThe maker's own figure. Worth reading alongside the dimensions below rather than on its own — two bags of the same litreage can want very different frames.
Reach behind the saddle
15.5cm shorter on the Saddle-Bag Two 4.1LLength is the lever arm on the seatpost, and the longer lever is what makes a loaded pack sway. Shorter is easier to live with; longer usually means more volume. It is a trade, not a fault.
Depth
6cm shallower on the Saddle-Bag Two 4.1LDepth is what competes with the rear tire once the pack sags under load. On a small frame or a big tire this is the measurement that decides it.
Weight
80g lighter on the Racing Saddle Pack 7LEmpty 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
$133 between themManufacturer's price as we hold it.
Per litre
$10.41 per litre between themPrice divided by the maker's capacity. A crude measure that still catches the case where the dearer bag is also the bigger one, which the price alone hides.
