Bikone DCTech Threaded (ITA - BB30)

The Bikone DCTech Threaded Bottom Bracket is a high‑performance upgrade designed for riders who want a quieter, smoother and more efficient drivetrain across road cycling, gravel riding, MTB, commuter bikes and race builds. Built around advanced Dual Cup Technology (DC Tech) and available with ceramic or stainless steel bearings, it’s engineered to improve bearing alignment, reduce friction and deliver a consistent, refined pedalling feel—whether you’re rolling through Brisbane bunch rides or tackling long gravel adventures across Queensland.

Engineered for smooth and efficient power transfer

At the core of the DCTech system is Bikone’s Dual Cup design, which helps align the bearings more precisely within the frame. This creates a more stable interface between the crankset and frame, helping reduce unwanted movement, eliminate common bottom bracket noise, and improve long‑term durability. For riders chasing smoother power delivery and quieter riding, this translates to a drivetrain that feels efficient under load and consistent over time.

Ceramic or stainless bearing options

The Bikone DCTech bottom bracket is available in two bearing options to suit different riding styles:

• Ceramic bearings offer ultra‑low friction and a premium upgrade feel, ideal for performance road bikes, triathlon builds and riders chasing marginal gains.
• Stainless steel bearings provide strong durability and reliability for everyday riding, commuting, MTB and all‑weather use.

Both options are designed to handle real Australian riding conditions, including dust, moisture and long‑distance use.

Compatible with modern frames and cranksets

This threaded bottom bracket is designed to fit a wide range of current frame standards and crank systems, making it a versatile choice for bike builds and upgrades.

Frame standards:

• BSA (English thread)
• ITA (Italian thread)
• T45
• T47 Internal
• T47 External
• T47a

Crank spindle compatibility:

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

This broad compatibility makes it suitable for upgrading popular road and MTB drivetrains including Shimano Ultegra, Dura‑Ace, GRX, SRAM Force AXS, RED AXS and SRAM Eagle setups.

Built for Australian riding and bike shop servicing

The Bikone DCTech bottom bracket is well suited to Brisbane and Queensland cycling conditions, where riders often face heat, humidity, grit and wet roads. Its sealed construction is designed to help protect bearings from contamination, reducing wear and extending service intervals.

It’s also a popular choice for riders booking professional bicycle services, including:

• bottom bracket replacement
• drivetrain servicing and tuning
• bike fitting and performance upgrades
• custom builds and wheel upgrades

Local bike shops regularly install bottom brackets alongside complete drivetrain services to ensure optimal alignment, correct torque and long‑term reliability.

Easy threaded installation

The threaded design makes installation straightforward compared to many press‑fit systems. It can be installed using standard tools, making it suitable for both professional workshop fitting and experienced home mechanics. This ease of service adds to its appeal for riders who want a high‑performance component that’s also practical to maintain.
