Bottom bracket Shimano BB86-92

• The BIKONE DCTech BB86-92 BB30 crankset is designed for cyclists who demand the best in performance and durability at the best price, whether tackling tough mountain trails or cruising on smooth roads.
• With our Double Cup Technology (DC Tech) and high-quality steel bearings, you will experience one of the smoothest rides.
• Double cup technology. Two aluminum cups perfectly align the bearings on each side, creating a solid central joint that eliminates any noise or movement issues.
• This crankset uses chrome steel bearings (ABEC5 /P5 - 2RS).
• The cups of our bottom brackets are made from aerospace-grade 7075 aluminum, a high-strength aluminum to which we apply a T6 treatment. This makes the material harder and more durable, ensuring that our cups maintain maximum performance over time.
• Completely waterproof. Axial seals in the bearings and fully sealed on all surfaces.

Note: For correct compatibility, mountain cranks should always be mounted on mountain frames and road cranks on road frames.
