Silca 40mm Threaded Valve Extender Kit with Speed Shield
Designed and created to extend valves and protect rims from valve nut damage, eliminate valve stem rattle and improve aerodynamics, the Silca 40mm Threaded Valve Extender Kit with Speed Shield is ideal for both tubeless and standard removable valve stems.
The valve extenders are made with high-precision CNC machined aluminium with full external threads, and incorporating Speed Shield into the 40mm Threated Valve Extender Kit actually improves aerodynamics up to 0.5 watts at 30mph. It’s the little things that make all the difference.
