Bikon DCTech T47-i Ceramic Bottom Bracket for Shimano

BIKONE DCTech T47 Internal Bottom Bracket — Ceramic for Shimano

Engineered for silence. Built to last.

For the rider who refuses to compromise, the BIKONE DCTech T47 is a precision-engineered bottom bracket that delivers buttery smooth power transfer, zero noise, and exceptional longevity. Whether you're grinding up technical singletrack or laying down watts on the tarmac, this BB raises the bar.

Dual Cup Technology (DCTech) At the heart of this bottom bracket is BIKONE's proprietary Dual Cup Technology — two perfectly aligned aluminium cups that form a solid, seamless center joint. The result is a completely rattle-free, play-free interface that eliminates the creaking and movement issues that plague lesser bottom brackets.

Hybrid Ceramic Bearings Fitted with ABEC5 / P5-rated hybrid ceramic bearings, the DCTech T47 spins with noticeably less resistance than standard steel alternatives. Ceramic balls are harder, lighter, and smoother — meaning less energy is lost with every pedal stroke, and the bearings last significantly longer under load.

Aerospace-Grade Aluminium Cups The cups are precision-machined from 6061 aluminium and treated with a T6 heat process that dramatically increases hardness and corrosion resistance. The same material standard used in aerospace applications ensures your investment holds up through thousands of kilometres and all-season riding.

Fully Sealed Protection Axial seals on the bearings plus full-surface sealing across all contact points keep water, mud, and debris completely out — critical for consistent performance in wet or dirty conditions.

Lightweight Design With a reduced pin count and machined aluminium construction, this bottom bracket comes in at just 113 grams — keeping your drivetrain lean without sacrificing any structural integrity.
