Blackbird

UDH Bolt

The Blackbird UDH Bolt delivers a simple yet striking upgrade for any bike running a Universal Derailleur Hanger (UDH). Crafted from precision-machined, anodized aluminum, this bolt adds a subtle pop of color while maintaining the clean, purposeful look riders expect from a well-built machine.

Beyond the aesthetic boost, its reverse-threaded design ensures the bolt stays secure when tightening or loosening the rear axle—no more mid-ride surprises or loose hardware. Perfectly color-matched to Blackbird faceplates and seat collars, it’s a finishing touch that ties the entire build together.

• Durable anodized aluminum construction resists corrosion and adds vibrant style
• Reverse threading keeps the bolt secure during axle adjustments
• Color-matched compatibility with other Blackbird components for a cohesive look
• Ideal for riders who appreciate both performance and precision detailing

Small part, big detail—the Blackbird UDH Bolt proves that every piece of your bike can reflect both function and finesse.
