RNCBMX Grade 23 Titanium Stem Bolts

Precision CNC machined from medical implant-grade Grade 23 (6Al-4V ELI) titanium, RNCBMX stem bolts are engineered for riders who demand the ultimate combination of strength, durability, and low weight.

Unlike conventional Grade 5 titanium fasteners, Grade 23's low-interstitial chemistry provides significantly higher fracture toughness, allowing the material to better resist crack initiation and propagation under repeated impacts and cyclic loading. Every bolt is precision heat treated and aged to achieve approximately 170,000 psi ultimate tensile strength, producing an exceptional balance of high strength, fatigue resistance, and durability.

Whether you're riding street, park, trails, or racing, RNCBMX Grade 23 stem bolts are designed to provide maximum confidence where it matters most.
