It's so strong, and so hard, that ordinary quick-releases can't bite into it like steel or aluminum. So we use vertical dropout slots to maintain perfect wheel alignment. No matter how hard you're cranking, the wheel won't slip. And the vertical design, coupled with Merlin's painstakingly precise construction, ensures faster, more accurate wheel changes, too.

Despite their awesome strength, our drops are 46 percent lighter than steel. But they'll never rust or corrode. And they'll never let you down.
