Dual Cup Technology for Better Alignment and Efficiency

Bikone’s Dual Cup Technology is engineered to improve the connection between the frame and crankset, supporting accurate bearing alignment and smooth power transfer. A well‑aligned bottom bracket can help reduce drivetrain drag, minimise creaks, and improve bearing life over time.

This makes the DCTech threaded bottom bracket a strong choice for riders upgrading a high‑end frame, building a new bike, or replacing a noisy or worn factory bottom bracket.

Ceramic or Stainless Bearing Options

Choose the bearing option that best suits your riding style and budget.

Ceramic bearings are designed for riders seeking ultra‑smooth rotation, reduced friction and premium long‑term performance. They are ideal for race bikes, fast road builds, triathlon bikes and performance gravel setups.

Stainless steel bearings offer excellent durability and reliability for everyday training, commuting, MTB and all‑weather riding.

Both options are designed to handle real‑world conditions including dust, rain, humidity and high‑kilometre use across Brisbane, Queensland and Australia.
