RISK RA111 Aluminum Presta Valve Nuts with O-Rings & Valve Tool

The RISK RA111 Aluminum Presta Valve Nut Kit is designed for bicycles using Presta valves, including road bikes, mountain bikes, fixed gear bikes, gravel bikes, and tubeless wheel setups. Compared with standard steel valve nuts, the lightweight aluminum alloy design helps reduce unnecessary wheel weight while providing a clean and secure valve installation.

Each kit includes 2 aluminum Presta valve nuts, 2 rubber O-rings, and 1 multifunction valve tool. The O-rings help cushion the contact between the valve nut and rim, reducing vibration and protecting the rim surface. The included blue valve tool makes installation easier and can also be used for removable Presta valve core installation/removal and Presta valve extender installation/removal.

With a streamlined shape, lightweight construction, and RISK branded packaging, this kit is a practical upgrade for wheel maintenance, tubeless valve installation, and replacement of loose or missing valve nuts.

Note: Suitable for Presta valves only. Please tighten until secure; do not overtighten. Valve stems, tubes, tubeless valves, rims, tires, and other accessories shown in images are for demonstration only and are not included.
