The regular Zipp Titanium and Steel skewers produce plenty of clamping power in most conditions and are certainly very light and aero. These Disc skewers seriously up the ante by producing extra clamping force disc brake wheels require. They have a longer and more generous lever that makes securely clamping the wheel a little easier. Some riders might find them better than stock Zipp skewers even on a non-disc brake bike in terms of reducing phantom creaks and having a lever that is easier on the hands.
