Description

The BIKONE DCTech T47 Internal dub bottom bracket is designed for cyclists who demand the best in performance and durability, whether you´re tackling tough mountain trails or cruising on roads. Thanks to our Dual Cup (DC Tech) technology and our high-quality bearings, you´ll experience the smoothest ride.
For Sram dub wide cranks, it is necessary to purchase a Dub Wide adapter kit. For correct compatibility, mountain cranks should always be mounted on mountain frames and road cranks on road frames.
Features:
– Dual Cup Technology. Two aluminum cups that perfectly align the bearings on both sides, creating a solid central joint that eliminates any noise or movement issues.
– This bottom bracket uses Chronium steel bearings (ABEC5 / P5 – 2RS).
– The cups of our bottom bracket axles are made of 6061 Aluminum, an aerospace-grade aluminum with high corrosion resistance on which we apply a T6 treatment. This makes the material harder and more durable, ensuring that our cups maintain maximum performance over time.
– Fully sealed. Axial seals on the bearings and completely sealed on all surfaces.
– Lighter. The number of pins on this bottom bracket has been reduced to make it lighter.
