Eastern Bikes Nomad Cranks Eastern Bikes Nomad cranks are the ultimate BMX crankset! Arms and spindle are made of heat-treated chromoly, but the heat-treating takes place at different times so that no strength is compromised; a feature not seen in conventional 2-pc style cranks. 19mm 48 spline drive side spindle with 8 spline non-drive side. Heat-treated, internally-butted chromoly design for additional strength and light weight. Right and Left side drive compatible 27oz
