Federal V2 Mid Bottom Bracket

This is a Mid bottom bracket, which is the standard for most modern BMX frames. If your frame is designed for a Mid BB, this will fit; however, it will not work with Spanish, American, or Euro bottom bracket shells.

You must match the spindle diameter of your bottom bracket to the spindle diameter of your crankset. This model is available in 19mm, 22mm, and 24mm options, so check your crank specifications before ordering.

The included spacers allow you to fine-tune the chainline and ensure your cranks are centered properly. While the main axle spacer is optimized for Federal's 2020 frames, the extra rings provide the necessary versatility to achieve a stable fit on a wide variety of other frame geometries.

While the repeating logo on the bearing covers adds a clean, branded look to your bike, they also serve to protect the bearings from dirt and debris, helping maintain a smooth rotation over time.

This is an external bottom bracket, meaning the bearing cups sit outside the frame shell. This design is standard for Mid bottom brackets and provides a solid, durable base for your crankset.
