DCTech Dual Cup Technology
Bikone’s DCTech system is designed to improve the way both bottom bracket cups align inside the frame shell. Correct alignment between the left and right bearings is critical because poor alignment can increase drag, cause premature wear and create the creaking noises commonly associated with poorly fitted bottom brackets.
Benefits include:
- Smoother crank rotation
- Reduced bottom bracket creaking
- Better bearing support
- Improved drivetrain efficiency
- More consistent power transfer under load
- Better long-term bearing performance
T47 Internal Threaded Design
T47 Internal combines the large-diameter stiffness benefits of modern bottom bracket shells with the serviceability of a threaded system. It gives riders a secure threaded interface while keeping the bearing system neatly integrated inside wider shells.
Precision Aluminium Cups
The aluminium cups are machined to provide an accurate bearing seat and a strong interface with the frame threads. This helps the bottom bracket stay stable under pedalling loads, especially when climbing, sprinting or riding rough gravel.
Stainless Steel Bearing Option
The stainless steel bearing version is the practical option for riders who want durability, value and dependable all-weather performance.
Best suited for:
- High-mileage road riding
- Gravel and mixed-surface riding
- Wet-weather training
- MTB use
- Commuting
- Riders prioritising long service life over marginal gains
Ceramic Bearing Option
The ceramic version is designed for riders chasing a smoother, lower-friction drivetrain feel.
Best suited for:
- Road racing
- Triathlon
- Criterium racing
- Premium gravel builds
- Lightweight custom bikes
- Riders focused on drivetrain efficiency
Fully Sealed Protection
The fully sealed construction helps protect the bearing system from dust, water, grit, sweat and road spray. This is especially useful for Australian conditions, where bikes regularly face humidity, dry dust, summer storms, rough chip seal and gravel contamination.
Noise Reduction Focus
A bottom bracket is a small component, but when it starts creaking, the whole bike feels tired. The Bikone DCTech T47 Internal is built to create a more stable and refined crank interface, helping reduce unwanted movement and restore a quiet, smooth ride feel.
