Zipp Super 9 clincher pics. Both sides of the wheel are shown, with a close-up of the valve opening from both sides. The first photo is of the unmodified side of the valve. The second photo shows you how just a little high/chamfering was added to make a pump head fit more easily. Minor but useful adjustment and no change to the foam inner core.
