Helix Race GR chainrings are gravity optimized direct mount chainrings designed to withstand the punishment of downhill, bikepark, and freeride disciplines. They’re crafted of AL-7075-T6, and highly CNC optimized for minimal weight penalty, and great looks. Paired with Helix Race GR Cranks, -7mm offset GR chainrings produce a 56.5mm chainline suitable for most long-travel bike geometries. Featuring e*thirteen’s M4 narrow-wide tooth profile, they deliver improved chain retention, reduced noise and system wear, and seamless compatibility with both Shimano and SRAM drivetrains, (including T-type).
