Bikone DCTech T47 Internal Sram Dub 29mm bottom bracket

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.
