Aluminium strength at XC weight
e*thirteen builds the Helix Race as its top aluminium alloy crank: Enduro-rated arm strength in an XC-weight package, with CNC machining through the arm to cut mass without cutting stiffness. It's sold as a crank only — no bottom bracket and no chainring — so pick a direct-mount Helix ring and a BB92 or BB30 bottom bracket to suit the frame.
