Bikone Dctech BSA_24 Ceramic Aero UAE bottom bracket 2026

The BSA Road Ceramic Aero UAE Bottom Bracket for Shimano is the lightest and most refined version yet: 17 grams lighter, built with a fully smooth aero cup, and engineered for smoother, more efficient rotation through hybrid ceramic bearings. Developed in collaboration with UAE Team Emirates, it helps you save watts with every pedal stroke for even greater marginal gains, turning small improvements into real performance on the road.

More aerodynamic
Aerodynamic profile with a completely smooth cup. Installation notches hidden on the inside, reduces airflow interference and turbulence around the area.

Weight reduced to 77 grams
With a brand-new design, we have reduced the weight by 17 grams compared to the previous version, with every shape engineered to eliminate unnecessary material.

Marginal gains taken to the next level
In performance cycling, small improvements create big differences. Less weight, less drag, less friction, each gain adds speed. Engineered for those who chase every advantage.

Tech Specs

• Crankset diameter: 24mm (Shimano)
• Frame width: 68 mm (Compatible with road bikes)
• Frame diameter: BSA
• For Threaded frames
• Producer's weight: 77 g

Features

• 77 grams, our lightest bottom bracket to date. 17 grams lighter than the previous version.
• New design. Every shape and structural decision has been made to remove unnecessary grams.
• Aero Cup. One of the cups features a fully smooth outer surface with no external notches, as installation notches are located internally. This profile reduces airflow turbulence around the area and ensures a more aerodynamic integration with the frame.
• Hybrid Ceramic Bearings (ABEC5 /P5 – 2RS).
• Made of 7075 Aluminium, a high-strenght aerospace-grade aluminium on which we apply a T6 treatment. This material allows us to remove weight without compromising performance.
• Completely protected. Axial seals on bearings and O-rings to fully protect all surfaces.

Included

• BSA Road Ceramic Aero UAE Bottom Bracket for Shimano
• Tool for Left side installation. (Internal notches)
• Tool for Right side installation (Regular BSA tool)
• Two extra seals for extra protection.
