This bag stays on my bicycle all the time . I've got the basic tools and such for road side repair . I was unsure about the bag due to its narrowness . I like the two strap design for the seat rails . It feels more stable than the one strap wrap around , of my old bag .
Larger than I would use on my road bike, this is perfect for my gravel bike. It holds two tubes, two CO2 canisters and inflator head, a multi tool, tire levers, and miscellaneous, such as keys or cash. My jersey pockets are left free for phone, clothing, mini-pump and food. Narrow profile is snug and secure and eliminates rubbing on my inner thighs.
