The Bikone DCTech Press Fit PF30-73a Bottom Bracket is a high-performance drivetrain upgrade designed for riders using PF30-73a press fit frames who want smoother pedalling, reduced drivetrain noise and long-lasting bearing performance. Built with Bikone’s advanced Dual Cup Technology (DC Tech), this bottom bracket is engineered to improve bearing alignment, reduce friction and deliver a more stable connection between your crankset and frame.

Available for Shimano 24mm, SRAM DUB 29mm and 30mm BB30 crank spindles, with either ceramic bearings or stainless steel bearings, this bottom bracket is a smart choice for road bikes, gravel bikes, MTB builds, endurance bikes, commuter bikes and high-performance race setups.

For cyclists in Brisbane, Queensland and across Australia, it’s an ideal upgrade when replacing a worn bottom bracket, solving press fit creaks, improving drivetrain efficiency or completing a premium bike service.

Designed for PF30-73a press fit frames

The PF30-73a frame standard is used on performance bikes that require precise bottom bracket fitment and accurate bearing alignment. Because press fit systems rely on the relationship between the frame shell, bearing cups and crank spindle, quality installation and component design are essential.

The Bikone DCTech system helps create a secure and stable bottom bracket interface, reducing unwanted movement and improving long-term drivetrain performance.

Dual Cup Technology for smoother power transfer

Bikone’s Dual Cup Technology is designed to align the bearings more accurately across both sides of the frame. This improves stability, reduces side loading and helps prevent common issues such as creaking, rough rotation and premature bearing wear.

For riders pushing hard efforts on climbs, sprinting in criteriums, grinding through gravel or riding long endurance kilometres, better bearing alignment can create a smoother and more efficient pedalling feel.

Ceramic or stainless steel bearings

Choose the bearing option that best matches your riding goals.

Ceramic bearings are designed for riders chasing low-friction performance, smoother rotation and maximum drivetrain efficiency. They are ideal for road racing, triathlon, high-end gravel bikes, lightweight builds and riders focused on marginal gains.

Stainless steel bearings offer excellent durability and dependable everyday performance. They are a practical option for MTB, commuting, wet-weather riding and high-kilometre training bikes.

Both options are built to handle Australian riding conditions, including heat, humidity, rain, dust and rough road surfaces.

Compatible crank spindle options

This PF30-73a bottom bracket is available for the most common modern crank standards:

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

This makes it suitable for popular drivetrain systems including Shimano Ultegra, Dura-Ace, GRX, SRAM Force AXS, SRAM RED AXS, SRAM Eagle and compatible 30mm crank setups, depending on your frame and crank configuration.

Ideal for bike servicing and drivetrain upgrades

The Bikone DCTech PF30-73a bottom bracket is a strong upgrade for riders booking a professional bike service or building a high-performance bike from the frame up.

Common installation use cases include:

bottom bracket replacement
press fit creak repair
Shimano crankset installation
SRAM DUB crank conversion
30mm crankset setup
drivetrain service and tuning
gravel bike upgrades
MTB maintenance
race bike preparation
custom bike builds

Professional installation is recommended to ensure the PF30 shell is inspected, contact surfaces are prepared correctly, bearings are seated evenly and crank preload is set to specification.

Built for smooth, quiet and durable performance

The sealed bearing design helps protect against water, dirt and road grit, reducing contamination and extending service intervals. Whether you are training on Brisbane roads, riding Queensland gravel, racing criteriums or commuting daily, the Bikone DCTech PF30-73a bottom bracket is built to keep your drivetrain running smoothly.
