Bikone Ceramic bottom bracket Shimano

• The BIKONE DCTech T47 internal ceramic bottom bracket for Shimano is designed for cyclists who demand the best in performance and durability, whether tackling tough mountain trails or enjoying road rides.
• With our dual cup technology (DC Tech) and high-quality ceramic bearings, you'll experience the smoothest rides.
• Dual cup technology. Two aluminium cups that perfectly align the bearings on either side, creating a solid central joint that eliminates any issues with noise or movement.
• This bottom bracket uses hybrid ceramic bearings (ABEC5 / P5 - 2RS).
• The cups of our bottom brackets are made from 6061 aluminium, a high-strength aerospace-grade aluminium with excellent corrosion resistance, which we treat with T6. This makes the material harder and more durable, ensuring our cups maintain their peak performance over time.
• Completely sealed. Axial seals in the bearings and fully sealed on all surfaces.
• Lighter. The number of pins on this bottom bracket has been reduced to make it lighter.
• Compatible tools: Parktool BBT-47-16 or similar: Ø52mm outer and Ø48.2mm inner. 16 pins.

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