CeramicSpeed 386EVO Bottom Bracket

This bottom bracket is designed to fit 386EVO frames and is compatible with 24mm spindle cranksets. It is a precise interface, so ensure your crankset spindle diameter matches the 24mm specification before installation.

Ceramic bearings are harder, smoother, and lighter than steel, which significantly reduces friction and energy loss while you pedal. They are also highly resistant to corrosion, meaning they typically maintain their performance longer than steel alternatives in various riding conditions.

The non-contact seal is engineered to protect the internal bearings from contaminants without creating drag against the spindle. This design choice prioritizes maximum efficiency and low friction, making it ideal for riders looking to shave every possible watt.

While CeramicSpeed bearings are highly durable, they still benefit from periodic inspection and cleaning, especially if you ride in wet or muddy conditions. Because these are precision components, we recommend following the manufacturer's specific maintenance guide to ensure the longevity of the ceramic balls and races.

Each unit is hand-built and arrives pre-lubricated with CeramicSpeed's optimized grease. It is ready to install straight out of the box without any additional preparation.
