The Straight Line B2-I Stiffy Wakeboard Handle Utilizes the standard B2i technology, “stiffy” sidebars and the short loop configuration. This handle is found in the quivers of those who seek a high performance, less expensive version of the carbon handle. The sidebars won’t collapse onto itself while handle passing, creating a quicker and more true pull when initiating your spin.B2-I Interchangeable System: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.Matrix Grip:Close to 33% of raised surface with mellow transitions create a grippy but comfortable feeling. The inverted diamond pattern gives you just enough room to sink your fingers in to pull out those sketchy landings. The Matrix grip is offered in Straight Lines 1.1" diameter Single Density technology.
