The star ratchet system in the freewheel guarantees that all ratchet teeth are engaged – unlike with pawl systems, where in the worst case scenario only one pawl is engaged leading to high loads on the hub and bearings. This can result in total failure if too much force is exerted (like on steep climbs).
The 17 mm oversize rear hub axle is double butted for lower weight and maximum stiffness.
Not only do straight-pull hubs have a more modern design, but there is also no contact between the spokes thus eliminating spoke noise. This prevents the spoke heads from working themselves into the flange.
