Oveja Negra Gearjammer Seatpack vs Restrap Saddle Bag
Two seat packs, measured against each other on the figures that decide whether they work on a bike.
The short answer
The Gearjammer Seatpack takes capacity, how far it reaches back and tire clearance; the Saddle Bag takes price. 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.
Capacity
1L more in the Gearjammer SeatpackThe 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
2cm shorter on the Gearjammer SeatpackLength 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
2cm shallower on the Gearjammer SeatpackDepth 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.
