Origin 8 Alloy Crank Arm Set
Best modular upgrade for cyclists seeking durable, direct-mount crank performance.
This is a straightforward, no-nonsense upgrade for riders looking to modernize their drivetrain without overspending. By adopting the versatile SRAM 3-bolt standard, it opens up a massive ecosystem of chainrings and spiders, though you sacrifice the proprietary refinement of high-end, brand-specific cranksets for pure, modular utility.
