Crupi Bars Our full line of bars were designed with input from top riders of all ages in order to produce the best bar in each size category.  The smaller bars feature flatter bends and numerous rises to fit everyone's needs.  The taller bars feature a slightly more swept back bend, lower cross bars and also come in sizes to fit all.   Our bars are constructed of the finest materials available.  They are built strong where they need to be and built light where they can be.
