The Straight Line B2-I Wakeboard Handle is the handle that everyone should be riding this year, interchangeable bar system, two pencil floats and Straight Line"s new short loop configuration leaves you with no excuses for not getting a new Straight Line Handle.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.
