e*thirteen has lots of love for aluminium.

Knowing weight, strength and looks were top priorities for riders, they went after all three with a vengeance. The Helix R is their top-of-the-line aluminium alloy crank.

Forged AL-6066-T6 arms deliver Enduro strength in XC weights and it took a 30mm Forged AL-7050-T7 spindle and massive amounts of CNC work to get there. CNC detail can be seen all over every surface for the ultimate in tech bling and weight savings for your ride. Designed to be compatible with Shimano and Sram 11 and 12-speed drivetrains, modern hub spacing, and bottom brackets. Helix R cranks can achieve boost and super boost chainlines with their flip-flop direct mount chainrings.
