Creak-Free Solution
Creaking noise is caused by a gap between BB and frame, also by contaminants in the bearing. Thanks to its unique structure, creaking issues of press-fit BB are eliminated.

"Thread-in structure"
Left and right cups are integrated by thread-in structure, which prevents noise, improves bearing life, reinforces the frame and adds stiffness to the bottom bracket area.

"Gasket-ring"
Original system for smooth and secure fitting
Gasket-rings placed under the fringe of the cups, are squeezed between surfaces to fill the clearance and provide secure fitting.
*Replacement gasket ring sold separately.

"Special seal"
Special seal keeps contaminants out of the bearing and ensures longer product life. So, service and maintenance of the bearing are not required.
The easy installation/removal system reduces the risk of damage to the frames, and simplifies maintenance work of the internal cables. BB is reusable after removal from the bottom bracket shell.


Made-in-Japan, highest grade, high precision ceramic bearings are used to ensure super smooth and long-lasting rotation. Cyclists need to adjust power and cadence depending on terrains, so the ceramic bearing is most effective as less energy is required to turn the crank. It offers remarkable performance gain under high load conditions such as competitions.

*Dedicated tools to ensure workability of installation and removal (sold separately). "TL-PWS BB Wrench Set"
