DCTech Dual Cup Technology
Bikone’s DCTech system is designed to improve bearing alignment across both sides of the bottom bracket shell. Better alignment helps reduce the unwanted movement that can cause creaking, friction, rough pedalling and premature bearing wear.
Key benefits include:
- Smoother crank rotation
- Quieter drivetrain performance
- Better power transfer under load
- Improved bearing support
- Reduced chance of bottom bracket creaks
- More refined pedalling during climbing and sprinting
T47a Threaded Interface
T47a combines the large-diameter stiffness benefits of modern oversized bottom bracket shells with the serviceability of a threaded system. Compared with many press-fit designs, a threaded T47a bottom bracket can be easier to install, easier to maintain and less prone to noise when fitted correctly.
Precision Aluminium Cups
The CNC-machined aluminium cups provide a stable bearing platform and accurate interface with the frame. This is important because bottom bracket performance depends heavily on alignment, shell fit and bearing support.
Stainless Steel Bearing Option
The stainless steel bearing version is ideal for riders who want strong everyday durability and low-maintenance reliability.
Best suited for:
- High-mileage road riding
- Gravel and mixed-surface riding
- Wet-weather training
- MTB use
- Commuting
- Riders prioritising value and longevity
Ceramic Bearing Option
The ceramic bearing version is aimed at riders chasing lower friction and a smoother drivetrain feel.
Best suited for:
- Road racing
- Triathlon
- Criterium racing
- Premium gravel builds
- Lightweight custom bikes
- Riders chasing marginal gains
Sealed Bearing Protection
The sealed bearing design helps protect against dust, grit, road spray, sweat and moisture. This is especially valuable for Australian conditions, where bikes often deal with dry gravel, humid summers, sudden storms, rough chip seal and high weekly kilometres.
