    Helix Cranks proven forged AL-6066 alloy for trail weights and Enduro strength and durability. Engineered with weight reduction features into the mold, resulting in a sleek, minimalist aesthetic. CNC cuts further optimize weights for a crank that's equally at home on long singletrack days and for bikepark shuttles. The AL6066-T6 arms are paired with a 24mm heat treated chromoly spindle, resulting in a crankset that hits way over its price point.
    Exemplifying cross compatibility, Helix Cranks fit with flip-flop Helix R or Helix Chainrings in a range of colors from 28 to to 34t and can achieve both Boost and SuperBoost chainlines, and perform equally well with both SRAM and Shimano 11 and 12-speed drivetrain systems. Equipped with a self-extractor bolt system, and creak-free proven Quick Connect interface, you get all the benefits of higher-end cranks without a heavy price tag.
