Ceramicspeed 61901 Coated Single Bearing One Size Silver / Blue

Evolve your wheels with Ceramispeed bearings and go faster with less effort.

Ceramicspeed balls are rounder, harder, softer, stiffer, and lighter than other ceramic and steel balls from other brands.

They save energy thanks to their extremely low friction, and this lower rolling resistance contributes to increased pedaling power transfer.

That is why many professional teams and athletes choose them.
