Alloy Presta Valve Locknut

RideFarr Alloy Presta Valve Locknut is a lightweight, service-friendly upgrade for securing a Presta valve stem at the rim—ideal for riders who want a more stable valve interface for inner tubes, tubeless valves, and valve extender setups. The standout 12mm square O-ring helps keep the locknut seated against the rim to reduce movement and protect the rim’s valve hole contact area during use and inflation.

• Universal Presta compatibility - Fits all Presta valves for straightforward replacement or spares
• 12mm square O-ring - Helps stabilize the locknut against the rim and minimizes rattling or loosening from vibration
• 6061 aluminum construction - Lightweight alloy hardware that resists corrosion better than basic steel nuts
• Clean, low-profile retention - Keeps the valve stem properly supported for easier pump head attachment and more consistent handling during inflation
