Spank Oozy Trail Rims

  • Made with MGR Dynamal Alloy with a Shotpeen anodized, laser logos (Decal for green on black model)
  • Bead Bite™, OohBah™, Dynamal Alloy features
  • OOZY Trail 345 – It’s wider internal width improves tire spread, effectively increasing traction, without squaring tire profiles excessively, which can lead to reduced maneuverability and cornering traction.
  • OOZY Trail 395+ – Offers the perfect blend of strength and stiffness with unparalleled tubeless performance. The OOZY Trail 395+ rim’s 35mm internal width is the perfect solution for riders seeking an ultra-wide aggressive trail rim model that doesn’t tip the scales.
