Cybrei Bottom Bracket - BB-386-29

The CYBREI BB386 bottom bracket is specifically designed for the DUB system. This standard provides significantly more effective protection against dirt and moisture without compromising the proven smoothness and durability of CYBREI bottom brackets.

An integrated dust cover ensures a secure, precise fit on all models while protecting the entire bearing surface. This maintains performance over the long term—without compromise. Handcrafted CYBREI bearings reliably transfer power from the crank to the frame and offer exceptional durability and optimal efficiency.
