The Avian Cadence 2-piece BMX race crank — hollow forged 6066 aluminum arms, heat-treated 24mm 16-spline 4130 chromoly spindle, CNC-machined 7005 alloy 104mm BCD spider. The hollow forging process removes material from inside the arm cross-section — you get the outer dimensions of a larger arm with the weight of a smaller one. Available in Polished and Matte Black.
