Velo Orange Grand Cru Cartridge Bottom Bracket

This bottom bracket is designed for frames with a standard 68mm English-threaded shell, which covers the vast majority of vintage and classic road bikes. If your frame uses a different threading standard, such as Italian or French, this unit will not be compatible.

The Grand Cru uses a standard square taper interface, making it compatible with most vintage and modern square taper cranksets. However, you should verify that your crankset requires the same spindle length as the specific version of this bottom bracket you are purchasing to ensure proper chainline.

No, it is a sealed cartridge unit, meaning it is designed to be maintenance-free. The high-quality sealed bearings are protected from dirt and moisture, so you can simply install it and ride without needing to repack or adjust the bearings.

You will need a standard splined bottom bracket tool to tighten the aluminum cups into your frame. The package includes the necessary crank bolts, so you will only need a hex wrench or socket to attach your crank arms once the bracket is installed.

At 258g, this bottom bracket is quite competitive for a durable, steel-axle unit. While you might find lighter titanium or carbon options, the use of a hollow boron steel axle keeps the weight down while maintaining the strength and stiffness required for reliable performance.
