>>1597113check r/fixedgearbicycle, a lot of them ride without bottles
some frames are supposed to be mainly for track/crit racing so some of them don't even take a rear brake even though it's fairly easy to accommodate on a metal frame
some frames like the aventon mataro are supposed to be as affordable as possible
aventon ultro can take a bottle cage but it's a pricey full carbon frame and it's sold out
i would rather have track ends that are threaded for chain tensioner screws
