Just curious as to what sorts of handlebar bags folks are using. I'm riding a Marin Mt. Vision 2016, and want to get a handlebar bag so I can take quick park jaunts without having to sling a backpack or waist pack in order to carry spare tube, pump and tools. I was thinking of the Shimano Pro Discover Gravel Handlebar Bag, but ... I'd like to know what other options are out there that are working for people.
