Regarding the DT 240 rear, FWB wrote
They also offer a star ratchet upgrade which doubles the amount of teeth cutting the amount of movement prior to engagement by about half and shaving another 10 grams of weight from the hub. In my opinion this upgrade should be a standard feature in the hub.
Does the tar ratchet upgrade increase the drag? Leaving aside noise (is the upgrade noisier when freewheeling?) and cost, is there any downside to the upgrade?
