Ortlieb Seat-Pack QR 13L vs Salsa EXP Seatpack
Two seat packs, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Seat-Pack QR 13L takes how far it reaches back; the EXP Seatpack takes weight, 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
4 of the 6 things we can measure come out differently.
Reach behind the saddle
2cm shorter on the Seat-Pack QR 13LLength 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.
Weight
225g lighter on the EXP SeatpackEmpty 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
$75 between themManufacturer's price as we hold it.
Per litre
$5.77 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.
