Ceramic bottom bracket Dub T47

• The BIKONE DCTech BB86-92 dub Ceramic crankset is designed for cyclists who demand the best in performance and durability, whether on challenging mountain trails or smooth roads.
• Thanks to our Double Cut Technology (DC Tech), you'll experience the smoothest rides.
• For wide Sram dub cranks, it's necessary to acquire a Dub Wide Adapter Kit.
• Double cut technology. Two aluminium cuts that perfectly align the bearings on each side, creating a sturdy central joint that eliminates any noise or movement issues.
• This crankset uses hybrid ceramic bearings (ABEC5 /P5 - 2RS).
• The sleeves of our bottom bracket axles are made from 7075 aluminium, a highly durable aerospace-grade aluminium that we apply a T6 treatment to. This makes the material harder and more durable, ensuring that our sleeves maintain maximum performance over time.
• Fully sealed. Axial seals in the bearings and fully sealed on all surfaces.

Included spacers:

• Ø29mm 2x1mm
• Ø29mm 1x2mm
• Ø29mm 1×2.5mm
• Ø29mm 1×4.5mm
• 2x1mm O-ring
• Wide dub cranks require a wide dub adapter kit.

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