The speed-ez are for bikes that have no eyelets near the dropouts. I have them on my cross bike and so far they are working great. They attach directly to your fork and rear seat stays by means of basically rubber straps. The rear fender also attaches onto your break bridge between you seat stays. They are very secure and don't seem to rattle around much. Best of all they keep you nice and dry and help keep some of the road grime off your drive train.
