Bikone DCTech ITA Ceramic Bottom Bracket 30 mm

Bikone DCTech ITA Ceramic Bottom Bracket 30 mm

The Bikone DCTech ITA Ceramic is a premium threaded bottom bracket for frames using the Italian standard. It combines ABEC5 / P5 – 2RS hybrid ceramic bearings, 7075-T6 aluminium cups and Bikone's Dual Cup Technology (DC Tech) to deliver very smooth rotation, accurate bearing alignment and strong protection against water and contamination.

This version is designed for 30 mm spindle road cranksets fitted to an Italian-threaded ITA frame. It is a premium solution for many Rotor 30 mm road cranksets, including compatible ALDHU and VEGAST configurations, provided the crank manufacturer's spacer and preload requirements are followed.

Why choose the Bikone DCTech ITA Ceramic?

• Hybrid ceramic bearings: designed to reduce friction while providing strong dimensional stability and durability.
• ABEC5 / P5 precision: tight tolerances for smooth, consistent rotation.
• Dual Cup Technology: both cups work together to promote correct bearing alignment and reduce unwanted movement.
• 7075-T6 aluminium cups: high-strength, lightweight and durable material with black anodised finish.
• Enhanced sealing: 2RS bearings, axial seals and protected exposed surfaces.
• Serviceable design: Bikone replacement bearings and service parts are available.

Compatibility and technical specifications

Installation

• Bikone tightening torque: 30–35 Nm.
• Left / non-drive side: assembly grease.
• Right / drive side: low-strength threadlocker such as Loctite 222, as specified by Bikone.
• Tool: Bikone BBTOOL_444612 or compatible tool with 45.5 mm outer diameter / 44 mm inner diameter, 24- or 12-notch profile according to Bikone's ITA manual.
• Do not use carbon assembly paste or brake cleaner on the bottom bracket.
• Do not clean the bottom bracket directly with a pressure washer.

Velo-Perso tip: “30 mm” here refers to the crank spindle diameter, not to a BB30 frame standard. Your frame must use a 70 mm Italian-threaded ITA shell. This bottom bracket is therefore the interface between an ITA frame and a 30 mm road crankset.

Service parts and warranty

• Replacement kit/bearing: Bikone 30407 Ceramic for 30 mm spindle
• Bikone warranty: stated lifetime warranty on the external cups and 3 years on bearings/wear-related auxiliary components, subject to the manufacturer's terms.

In short

A strong premium choice for road bikes using a 70 mm ITA shell: precise ceramic bearings, rigid construction, effective sealing and replaceable service parts. Final compatibility always depends on the frame standard, crank spindle diameter and any spacers required by the crank manufacturer.
