tack on some removable drop outs to some slips. then tack the slips into your frame
some of us prefer riding brakeless, nothing to hit knuckles on, looks clean, seems to improve a riders style and flow, much more fun bombing hills brakeless to , but thats jus what i thinkYou could always buy a frame with brake mounts and then take the brake's off. Fair bit easier then buying a frame without mounts and putting them on.
Why wouldn't you want brake's? Do you live in the desert where it is flat?
