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.Features:forged, cnc machined alloy crank arms and 30mm al 7050-t7 spindle for down-country weight with enduro strengthcompatible with helix direct mount chainrings for boost superboost chainlineself extracting bolt system, and aps adjuster for ease of installation and serviceproven creak-free quick connect ring interfacemolded crank strike boots and thick, clear polymer protective decalsavailable in shorter arm lengths, starting at 160mm.
