Roll up, roll up, get your mid-ride snacks, phones, cameras and much, much more all at your fingertips! Well, maybe less fairground novelty and more utilitarian function but all the same, bags that sit right in front of you are likely to be the most frequently opened, shut, crammed, emptied and stained, so you want to make sure you get the right one. A pair of cylindrical stem bags is commonplace for tourers - one for snacks and one for litter. Top tube bags sit a bit more aerodynamically and out of the way but are often smaller than their stem mounted equivalents. Pick one or pick both being safe in the knowledge your gear will be at your fingertips.
