Bikone DCTech ITA Ceramic Bottom Bracket SRAM DUB 29 mm

Bikone DCTech ITA Ceramic Bottom Bracket SRAM DUB 29 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 lets you fit a SRAM DUB road crankset with a 28.99 mm spindle to an Italian-threaded ITA road frame. It is particularly useful for modern Italian frames using the ITA standard, including selected Pinarello models, while retaining a SRAM DUB crankset.

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 depending on the tool.
• 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: the DUB spindle is precisely 28.99 mm. This is the dedicated ITA/DUB version; do not confuse it with a BSA DUB bottom bracket or the 30 mm version. For DUB Wide cranksets, always check the spacer arrangement required by the crank manufacturer.

Service parts and warranty

• Replacement kit/bearing: Bikone 30407 Ceramic for SRAM DUB
• 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.
