As both fashion and function became high priorities in the watersports community, Straight Line invented the B2i interchangeable system. Building off the B2 bushing idea, Straight Line created a new bushing that uses nubbed extensions that reach deep into the aluminum bar and "click" into precisely drilled holes. The diameter of the bushing matches the elliptical shape of the aluminum bar's inner diameter, creating a durable and secure fit. To change a bar simply use the B2i tool, provided with the replacement bars, to release the two nubs and pull firmly on the bushing.
