The Gripper, now updated with an oversized 30mm strap that reduces shifting during rides, its minimalist design stows easily almost anywhere on your bike. It's ideal for carrying essentials on a quick ride, or in tandem with our larger packs on longer rides, moving weight off your back and freeing up valuable space for water and food. Keep the Gripper on your bike, and your chances of walking out of the woods are forever minimized.
