STRONGLIGHT 23mm Crank Dust Cap - Vintage Bicycle

The crankset is a focal point of any vintage build. This STRONGLIGHT dust cap, with its 23 mm diameter, is exactly the kind of detail that completes the assembly — machined from steel, made in France, and intended to press into the crank arm's dust cap recess.

Steel Construction and Precise 23 mm Diameter

A dust cap of this type threads into the crank arm to close off the extractor thread area. The steel material here is durable and carries the crisp machined look expected on French components of this era. The diameter, 23 mm, is a precise number to check against your crank arm before fitting. This dimension determines fit, not a generic range.

The product photographs are an integral part of the description. They show the condition of the surface and the shape of the part as it is now, not a catalog render. Look at the edges and the face — those are the areas that mattered in original fitment and still matter for final assembly.

For those restoring a complete bottom bracket assembly, the STRONGLIGHT Competition Bottom Bracket 35x100 French Thread 125mm Triple is a direct companion piece. If the focus is on the full wheel build, see also the MAVIC 500 RD vintage hub set for a matching period-correct drivetrain component.
