I have Frontrollers and a standard Cyclepro rear platform rack mounted on the front. Worked fine on an 1800-mile tour, except for the load riding high and forward, making steering slightly exaggerated. I've since bolted two 8mm tubes on the rack's struts and now carry the Frontrollers about 4-inches lower and a few inches more to the rear. Recently did a short week-long tour with that setup. Big improvement in handling, no problems with mounting, and very little expense.
