A lock nut to secure the stem at the wheel rim and a valve cap may also be present. The outer valve stem is manufactured in various lengths for different applications, and has a narrower diameter (6 mm) than Dunlop and Schrader valves (8 mm). The weakest point of a bicycle rim is usually the hole for the valve stem. The smaller hole for a Presta valve makes it possible to have extremely narrow wheels while maintaining sufficient strength in the wheel. The air pressure in an inflated tire holds the inner valve body shut.
