CeramicSpeed BB ALPHA Road

This specific BB ALPHA model is designed for frames with a 42mm bore diameter and a 68mm shell width. It is intended for use with cranksets featuring a 30mm spindle, so please verify your frame's bottom bracket standard is BB30 before purchasing.

The ALPHA uses grade-3 Silicon Nitride ceramic balls paired with hardened stainless-steel races. This combination significantly reduces friction and increases durability, allowing the bearings to last much longer than standard steel alternatives while offering a smoother pedal stroke.

The ALPHA features custom-engineered seals and precision dust covers specifically designed to keep moisture and contaminants out. This setup offers much better protection than standard bearings, making it a reliable choice for riders who frequently encounter rain or road grit.

Installation is straightforward thanks to the simplified spacer tube and lightweight cup design. While it is designed for a quick and precise fit, we always recommend using the proper press-fit tools to ensure the bearings are seated correctly without damage.

Because of the high-quality seals and durable ceramic materials, these bearings require less frequent maintenance than standard options. However, keeping the area clean and periodically checking for play will help ensure you get the maximum lifespan out of the unit.
