Bikone DCTech Press Fit BB86–92 (Shimano, Sram or BB30)
The Bikone DCTech Press Fit Bottom Bracket is designed for cyclists who want smoother pedalling, better drivetrain efficiency and long-lasting reliability from their bike. Built around Bikone’s Dual Cup Technology (DC Tech) and available with ceramic or stainless steel bearings, this bottom bracket is a high-performance upgrade for road bikes, gravel bikes, MTB, triathlon bikes, criterium race bikes and commuter bikes.
A quality bottom bracket can make a noticeable difference to how a bike feels under load. Whether you are replacing a worn press fit bottom bracket, chasing a quieter drivetrain, or building a premium performance bike, the Bikone DCTech system is engineered to reduce drag, improve bearing alignment and deliver a smooth, refined ride.
Ceramic or stainless steel bearing options
Choose the bearing option that best suits your riding style and maintenance needs.
Ceramic bearings are ideal for riders chasing the lowest friction and maximum efficiency. They are a strong choice for road racing, triathlon, time trial bikes, high-end gravel builds and riders focused on marginal gains.
Stainless steel bearings are a durable, reliable option for everyday training, commuting, wet weather riding and MTB use. They offer strong performance with excellent longevity in mixed riding conditions.
Both options are designed to handle Australian conditions, including dust, rain, humidity and long-distance riding.
