Precision Titanium MID Bottom Bracket Shell for BMX & Trials Frames – 68/73mm | 41.2mm ID | OEM/ODM Available
Engineered for professional BMX frame builders and custom bike manufacturers, our precision-machined titanium MID BB shell sets the new standard for lightweight strength in high-performance BMX and trials frames. Designed specifically for builders who demand the best, this component delivers aerospace-grade reliability with the exact specifications required for serious riding disciplines.
Why Choose Our Titanium MID BB Shell for Your BMX Frame Production?
✅ True MID Standard Compatibility
Features the critical 41.2mm internal diameter (ID) required for seamless MID bottom bracket integration. No compromises, no modifications—just perfect fitment for standard MID bearings.
✅ Aerospace-Grade Material Performance
Machined from Grade 5 Titanium Alloy (Ti-6Al-4V) , offering the highest strength-to-weight ratio available. Significantly lighter than steel, stronger than aluminum, with natural corrosion resistance that ensures your frames last a lifetime.
✅ Dual Width Options for Design Flexibility
Available in both 68mm (standard BMX trials) and 73mm (reinforced for dirt jump and aggressive riding) shell widths. One component, multiple frame applications.
✅ Builder-Friendly Precision Tolerances
CNC-machined surfaces guarantee perfect alignment during welding, while the raw titanium finish accepts standard frame building techniques. Clean integration into your production process.
✅ Performance-Driven Design
Critical BB stiffness translates to precise pedal control in technical sections, while significant weight reduction enhances overall bike handling—exactly what serious BMX and trials riders demand.
