e*thirteen Helix Race Lightweight Alloy MTB Cranks for Trail and Enduro Mountain Bikes

A premium alloy alternative to carbon cranks, with full CNC aesthetics and Enduro strength at Down Country weights. Paired with a Helix R chainring they are the ultimate upgrade in performance and style. Available in shorter arm lengths, starting at 160mm. Helix Race Aluminum Cranks are a top-of-the-line aluminum crankset that brings Enduro strength at Down Country weights, starting at just 556g. Extensively weight-optimized, almost every visible crank surface is CNC machined from a burly forged blank. The design leverages the modular spindle system of e*thirteen's carbon cranks with alloy arms that peak the strength-to-weight ratio scales. They come with custom molded crank boots for added impact resistance, an alloy extractor bolt system, and APS Adjuster. Compatible with Helix flip-flop chainrings, they can adapt to both Boost or Super Boost chainlines.
