Compatibility Notes

Designed for Shimano 24mm crank spindles.
Not compatible with SRAM DUB 29mm or BB30 / 30mm cranksets unless using the correct Bikone ITA model for those crank standards.
ITA is not the same as BSA, T47, BB30, PF30, BB86/92 or BBRight.
ITA threaded systems typically require careful thread preparation and correct left/right cup installation.
Professional installation is recommended to avoid cross-threading, poor preload or premature bearing wear.

Bikone DCTech Dual Cup Technology

Bikone’s DCTech system is designed to improve how the bottom bracket cups and bearings align inside the frame. Better bearing alignment helps reduce friction, unwanted movement and drivetrain noise, especially when pedalling under load.

Key benefits include:

Smoother crank rotation
Reduced creaking and clicking
Improved bearing support
Better power transfer during climbing and sprinting
More consistent drivetrain feel
Better long-term bearing life when correctly installed and maintained

ITA Threaded Reliability

Italian-threaded bottom brackets are often found on classic Italian road frames, premium steel frames, custom road bikes and selected high-performance frames. A quality ITA bottom bracket gives these bikes a secure, serviceable and smooth-running crank interface.

Shimano 24mm Compatibility

This model is built for Shimano 24mm cranksets, making it suitable for Shimano 105, Ultegra, Dura-Ace and other Shimano Hollowtech II-style road crank systems where the frame uses an ITA bottom bracket shell.

Ceramic Bearing Option

The ceramic version is best for riders wanting a smoother, lower-friction drivetrain feel.

Best suited for:

Road racing
Track bikes
Criterium racing
Premium Shimano Di2 builds
Lightweight custom road bikes
Riders chasing marginal gains

Stainless Steel Bearing Option

The stainless steel version is ideal for riders wanting durability, dependable weather resistance and strong everyday value.

Best suited for:

High-mileage road riding
Commuting
Wet-weather training
Gravel-style use where the frame allows
Riders prioritising long-term reliability

Sealed Bearing Protection

The sealed bearing system helps protect against sweat, dust, road spray and grime. This is especially useful in Brisbane and Queensland conditions where bikes regularly face humidity, summer storms, dusty roads and rough chip-seal surfaces.

Precision Aluminium Cups

The machined aluminium cup structure provides a stable bearing seat and accurate threaded interface. This helps maintain smooth rotation and reduces the likelihood of movement under pedalling load.

Frame Standard: ITA / Italian threaded
Typical Shell Width: 70mm
Thread Type: Italian 36mm x 24TPI

Fit Checklist Before Purchase

Before ordering, confirm:

Your frame uses ITA Italian threading
Your bottom bracket shell width is correct for ITA fitment
Your crankset uses a Shimano 24mm spindle
Correct spacers or dust covers are available if required
Threads are clean and undamaged
You have the correct installation tool

Fit Recommendation

We strongly recommend professional installation for ITA bottom brackets. The frame threads should be inspected and cleaned before fitting, with correct grease or thread preparation used according to the installation requirements. Correct crank preload is essential for smooth rotation and bearing life.

The Bikone DCTech ITA Shimano Bottom Bracket is ideal for riders who want to keep an Italian-threaded Shimano road bike running smoothly, quietly and efficiently.

Best Suited For

Riders replacing a worn ITA bottom bracket
Cyclists restoring or upgrading Italian-threaded road frames
Shimano Ultegra, Dura-Ace and 105 crankset users
Road racers and criterium riders
Track cyclists using compatible ITA frames
High-mileage road cyclists wanting smoother pedalling

Rider feedback around premium ITA and Shimano-compatible bottom bracket upgrades is generally positive when the correct standard is selected and installation is done correctly.

Common positive rider comments include:

Smoother crank rotation
Quieter pedalling under load
Reduced creaking compared with worn bottom brackets
Better feel during climbing and sprint efforts
Ceramic option feels refined on premium road builds
Stainless steel option gives dependable everyday durability
Threaded installation feels secure and serviceable
Excellent upgrade for classic or custom Italian-threaded frames

Most issues with threaded bottom brackets come from incorrect compatibility, damaged threads, poor preload, missing spacers, contamination or incorrect installation. This is why professional fitting is strongly recommended.

Why We Love It at Pedal Passion

We love the Bikone DCTech ITA Shimano bottom bracket because it gives Italian-threaded frames the drivetrain refinement they deserve.

Product Care

Install using the correct ITA-compatible bottom bracket tool.
Confirm Shimano 24mm crank compatibility before fitting.
Inspect and clean frame threads before installation.
Use correct grease or thread preparation as recommended.
Avoid pressure washing directly around the bottom bracket seals.
Check for play, roughness or creaking during regular bike servicing.
Set crank preload correctly after installation.
Keep the bottom bracket area clean after wet or dusty rides.
Replace or service bearings if rotation becomes rough or contaminated.
Have drivetrain noises diagnosed early before they cause further wear.

Warranty Information

Warranty coverage is subject to Bikone or retailer terms and conditions.
Warranty generally applies to manufacturing defects in materials and workmanship.
Normal bearing wear, contamination, incorrect installation, damaged threads, cross-threading, excessive preload, pressure washing damage, crash damage and misuse are generally not covered.
Professional installation is recommended for performance, safety and warranty protection.
Bearing lifespan depends on installation quality, weather exposure, cleaning habits, lubrication and service frequency.
