Familiarity: I've put it through the wringer
The DT Swiss 10 mm Thru Bolt Skewer has been a great help in securing the rear wheel on my Santa Cruz Butcher frame compared to the old 10mm qr. The spring loaded mechanism is great! I am able to put the lever in exactly the position I want with very little effort and creates the correct bearing preload every time.
