Bikone Ceramic Bottom Brackets : T45

Season:2026

Brand:Bikone

Code:DCTCT45_

A ceramic bottom bracket is only as good as the way it's held in the frame, and that's where Bikone start. It is also the reason we chose them over and above the likes of C-Bear.

Their Dual Cup Technology uses two aluminium cups that align the bearings on either side of the shell to one another and lock together in a solid joint in the middle. The bottom bracket then behaves as one part, even in a frame built to looser tolerances, which Bikone say eliminates noise and movement and gives smooth pedalling from day one.

Inside are hybrid ceramic bearings built to ABEC 5 / P5 precision, with ceramic balls running in steel races. Bikone choose ceramic for its corrosion resistance, dimensional stability, lower density and higher heat resistance as well as the friction reduction advantages - and then they seal it properly. Rather than lighter non-contact seals, which spin a fraction more freely but leave the balls open to grime, every bearing gets 2RS rubber contact seals on both sides, with axial seals on the bearings and the cups sealed on every surface. Moisture and grit stay away from the balls and races, and Bikone back the bearings with a three-year warranty. The cups are T6 heat-treated aluminium, and fitting or removal needs no special tools.

That sealing choice is the clearest difference between Bikone and CeramicSpeed, who we also stock. CeramicSpeed build for outright performance and price it accordingly. Bikone take ceramic bearings and balance them against everyday protection, at around 45% less than CeramicSpeed's BB Alpha. If you race and want every last gain, CeramicSpeed is the benchmark. If you want ceramic bearings sealed for the way most of us actually ride, this is where we'd point you.

Living with one is straightforward. Bikone guarantee the cups for life and the bearings for three years, and when the bearings eventually wear, a service kit replaces them while the cups stay in the frame.

Not sure which standard your frame takes? Send us the make, model and year and we'll tell you which Bikone fits.
