Care & Notes
Confirm the frame’s shell width, thread standard and required axle length before ordering.

Installation requires suitable bottom bracket tools and should be completed to the bicycle or component manufacturer’s recommended torque settings. Professional installation is recommended when compatibility or fitting requirements are uncertain.
