I'm running front/rear brakes right now with cheapie platforms that I tore off my Giant so I could ride the new IRO. I'm planning on getting Shimano clipless/platform pedals soon but if I had to rely solely on brakes and not skidding (say I'm panic braking or I decided not to wear the cleats that day), would it be safe to use just front brakes? I'm used to using my front brake only so it'd be a change but I'd eventually get used to it.
