C-Bear Ceramic Bearings Bottom Bracket PressFit 30 for 30mm ROTOR spindle cranks.
C-Bear Ceramic Bearings is a Belgian bearing specialist for ceramic ball bearings with excellent running properties and durability. All bottom brackets work without additional spacers and washers.
The MTB/cyclocross bearings are for riding in puddles and dirt road conditions. The special formulated grease and seals are specific to cater these riding conditions.
- The housings are made of aluminum and offer higher stiffness and precision compared to plastic, more stability and no tendencies to deform.
- The bearings lie close to the crank arm and ensure optimum stiffness and maximum force transmission.
- No additional parts such as spacers, adapter or shaft rings required.
Please note the table in the appendix to determine the right bearing.
