Premium Access & Style: CNC Aluminum 90-Degree Valve Stems

Upgrade your wheels with the Universal Parts Aluminum Bent Valve Stem Set. Engineered for riders who value both form and function, these 90-degree stems eliminate the struggle of checking tire pressure on wheels with large brake rotors or small hub diameters. CNC-machined from high-grade aluminum, these stems provide a permanent, bolt-on solution that is far more durable than standard rubber pull-through stems.

Technical Performance Features

  • 90-Degree Right Angle: Points the valve outward for effortless access with any standard air chuck or pressure gauge, regardless of rim size.
  • CNC-Machined Aluminum: Lightweight yet incredibly strong, these stems won't crack, rot, or tear like traditional rubber stems under high-speed centrifugal force.
  • 10mm Mounting Diameter: Precision fit for performance rims with a 10mm valve hole, ensuring a rock-solid, leak-proof seal.
  • Vibrant Anodized Finish: Available in Black, Blue, Orange, Red, and Silver to perfectly accent your bike’s color scheme or custom rim tape - Choose your color.

  • Color: Black, Silver, Orange, Blue, Red
  • Angle: 90 Degrees

Mechanic's Note: These are bolt-on stems. They feature a rubber grommet and a securing nut that is tightened from the inside of the rim. Pro Tip: These are best installed during a tire change. Because they are rigid aluminum, they won't flex or "flutter" at high speeds, providing a much more consistent seal than rubber stems on highway-speed scooters.
