Bontrager Comp Seat Pack

The 1.2-liter capacity is sized for the essentials. You can comfortably fit a spare tube, a multi-tool, a tire lever, and a CO2 inflator or a small patch kit.

Yes, the hook and loop straps are designed to be universal. They wrap securely around standard seat rails and the seatpost, making it compatible with almost any road, mountain, or hybrid bike.

The angled zipper allows the bag to open wider than a straight zipper would. This makes it much easier to reach inside and grab a specific tool without having to dump the entire contents of the bag onto the road.

The bag is made from durable polyester, which is water-resistant and handles road spray and light rain well. However, it is not fully waterproof, so you may want to put sensitive items like a phone or cash in a small plastic bag if you are riding in heavy downpours.

Yes, the bag features an integrated mounting tab specifically designed for clipping on a rear taillight. This is a great feature for maintaining visibility since the bag itself might otherwise obscure your seatpost-mounted light.
