No, this is a press-fit bottom bracket for 86.5mm shells and is not compatible with threaded (BSA) frames.
No, this bottom bracket is specifically sized for the 29mm SRAM DUB spindle diameter.
You need a press-fit tool compatible with 46mm bearing cups and a torque wrench.
Yes, the sealed bearings are designed to handle the rigors of off-road riding, though regular maintenance is recommended.
Maintenance frequency depends on riding conditions; however, a basic inspection and cleaning of the external surfaces should be done during your regular bike tune-up.
Remove the crank, clean the spindle and bearing interfaces, re-grease, and ensure proper torque when reinstalling.
Verify the frame shell width is exactly 86.5mm and that you are using a professional-grade press-fit tool; do not hammer the cups into the frame.
Check that the DUB preload adjuster on the crank arm is not set too tight against the bearing cover.
Installation of this bottom bracket requires a specialized press-fit tool designed for 46mm cup diameters. Before installing, ensure the frame's bottom bracket shell is clean and free of debris. Apply a thin layer of high-quality bike grease to the shell interface to prevent creaking and future seizing.
Compatibility Note: This model is designed for 86.5mm shell widths. Attempting to install this on a shell with different dimensions will result in improper bearing preload and potential damage to your crankset.
Care: To extend the life of your bearings, avoid using high-pressure water spray directly at the bottom bracket seals during bike washes, as this can force moisture past the rubber seals.
