The Bikone DCTech T47 Internal Bottom Bracket is a high‑performance upgrade designed for riders running modern T47 internal threaded frames who want improved drivetrain efficiency, smoother pedalling and long‑term reliability. Built with Dual Cup Technology (DC Tech) and available with ceramic or stainless steel bearings, this bottom bracket is engineered to deliver a consistent, low‑friction ride feel across road cycling, gravel, MTB and endurance builds.

For cyclists upgrading to a premium T47 bottom bracket is one of the most effective ways to refine drivetrain performance, eliminate creaks and get the most out of a high‑end frame.

Ceramic and stainless bearing options

The Bikone DCTech T47 Internal bottom bracket is available with two bearing configurations to suit different riding styles:

Ceramic bearings offer ultra‑low friction and maximum efficiency, ideal for performance road cycling, triathlon, time trial and riders chasing marginal gains.
Stainless steel bearings provide excellent durability and reliability, making them perfect for everyday riding, commuting, gravel and MTB use.

Both bearing options are sealed to help protect against dust, moisture and contamination, making them suitable for varied Australian conditions including wet rides and dusty gravel roads.

T47 internal compatibility with modern cranksets

Designed specifically for T47 internal threaded frames, this bottom bracket ensures a secure, stable fit while remaining easy to service compared to many press‑fit systems.

Frame standard:

T47 Internal

Crank compatibility:

24mm Shimano cranksets
29mm SRAM DUB cranksets
30mm BB30 cranksets

This makes it compatible with leading drivetrain systems including Shimano Ultegra, Dura‑Ace, GRX and SRAM Force AXS, RED AXS and Eagle, making it ideal for both road and off‑road builds.

Reliable, low‑maintenance performance

The high‑quality materials and sealed construction help reduce wear and corrosion, allowing for longer service intervals. Whether you’re riding daily, racing or training for endurance events, the DCTech T47 Internal bottom bracket is built to deliver consistent performance over time.

Easy threaded installation

Thanks to the threaded T47 design, installation is more secure and less prone to creaking compared to press‑fit systems. It can be installed using standard workshop tools, making it suitable for both professional mechanics and experienced home mechanics.

Dual Cup Technology for better alignment and power transfer

At the core of the DCTech system is Bikone’s Dual Cup Technology, developed to improve the alignment of the bearings within the bottom bracket shell. By ensuring both sides are precisely aligned, the system reduces drivetrain friction, improves power transfer and minimises common issues such as noise and premature wear.

For riders pushing hard efforts—whether climbing, sprinting or riding long training kilometres—this precision translates into a smoother, quieter and more efficient pedalling experience.

Built for Brisbane and Australian conditions

Cycling in Brisbane and Queensland often involves a mix of hot weather, humidity, wet roads and dust. The Bikone DCTech bottom bracket is designed with durability in mind, featuring a sealed bearing system that helps extend component life and reduce maintenance.

It’s a popular upgrade when combined with professional bike servicing and workshop installs, including:

bottom bracket replacement
drivetrain servicing and tuning
crankset installation and alignment
bike fitting and performance optimisation
custom builds and upgrades

Local bike shops regularly recommend upgrading the bottom bracket during a full bicycle service to improve ride quality and reduce drivetrain wear.
