PRACTICE WORKS bottom bracket BB30 M30 | PF30 73 mm for turn Girder M30 crank
The practice Works M30 bottom bracket is suitable for the use of the turn Girder M30 MTB crankset of Practice Works. A provided sleeve bottom bracket for all mountain bike frames with BB30 and PF30 standard is suitable. The bearing shells are, however, not press-fitted into the frame. The bottom bracket converts the BB30 / PF30 standard for BSA standard, so that the bearing shells sit outside the frame. When screwing the bearing shells to the bearing sleeve expands in BB30 / PF30 bearing seat. Unlike many other adapters that ensures a permanently tight fit in the frame and annoying clicking noises through a working internal bearing may be excluded.

NOTE: Due to different bearing inside diameter on the drive and non-drive side bottom bracket on the turn Girder suitable M30 crank. For assembly, the practice Works M30 BB tool is required.
