BBRight Outboard ZERØ Ceramic BB

Unlike standard press-fit bottom brackets that rely solely on a friction fit, this system threads the two aluminum cups together inside the frame. This creates a secure, unified structure that prevents the cups from shifting or micro-moving, which is the primary cause of creaking in press-fit shells.

This model is specifically designed for frames with a BBRight press-fit standard, which features a 79mm shell width and a 46mm shell inner diameter. Please verify your frame's specifications before purchasing, as it will not fit frames designed for other press-fit standards like BB30 or PF30.

This bottom bracket is designed for cranksets with a 24mm spindle diameter. It is an ideal choice if you are running a Shimano or similar 24mm crankset on a BBRight frame.

The Enduro ZERØ ceramic hybrid bearings offer lower rolling resistance and higher durability than standard steel bearings. While the difference is subtle, you will likely notice a smoother, more efficient pedal stroke, especially during long rides or under high-load conditions.

Yes, you will need a tool compatible with a 48.5mm, 16-notch pattern to properly tighten the cups. This is a standard size for many external bottom bracket tools, but it is worth checking your current toolkit before starting the installation.

One of the main advantages of this design is that it simplifies maintenance. Because the cups are machined aluminum and thread together, you can easily access and service or replace the bearings when necessary without needing to press out the entire assembly from the frame.
