A suitable choice for anyone replacing a worn press-fit bottom bracket on a compatible 89.5 / 92 mm frame with SAINT HOLLOWTECH II cranks.
The SM-BB71-41A is a press-fit bottom bracket designed for compatible frames with a 41 mm inner-diameter shell and an 89.5 or 92 mm shell width. It is intended for SAINT HOLLOWTECH II cranks, making it a practical replacement when your existing bearings are worn or your bottom-bracket interface needs refreshing.
The wide-spaced bearing layout supports the crank axle securely and helps maintain stable crank support as you pedal. Sealed bearings provide added protection against dirt and moisture, while the press-fit format installs directly into the compatible frame shell without threaded cups.
Check your frame shell dimensions and crank compatibility before ordering. The inner cover and O-ring are included for this SM-BB71-41A version; installation is specified with the TL-BB12 press-fit installation tool, and removal with the TL-BB13 tool.
