While maintaining the original weight, the conical ratchet design eliminates the need for a separate ring gear by integrating it directly with the ratchet mechanism, allowing pedaling force to be transmitted straight to the hub for improved efficiency. This integrated design features a larger diameter than traditional ratchets, accommodating a higher tooth count; for the same number of teeth, the load-bearing surface area increases by over 45%, enabling the system to withstand greater torque than traditional ratchets while remaining compatible with standard ratchet hubs.
