how to mount rear rack to single centered hole on rear fork - or other option
my wife has an older schwinn world, and wants to add a rear rack for her commute. after checking out her hookups, we noticed she doesn't have the traditional screw holes on either side of the seat post, or on the rear fork. instead it's just a single, centered hole on a cross bar between the rear fork (picture attached)
is there an adapter or something so we can fit a rack? she ordered the Topeak Explorer rack.
it was a fixie we converted to a single speed flywheel, so it doesn't have a read brake yet (just the front), is that where we would mount the rear brakes? If so, is there another option to mount the rack?
thanks for any help or suggestions.
