Description:

The Park Tool BBT-7 Lockring Wrench is used for installing and removing the lockring used on Shimano Dura Ace® 7700 and XTR® 950 Bottom Brackets. It is laser cut and engages five of the lockring's six notches for a precise, secure fit. The handle is vinyl dipped for comfort. While made specifically to fit Shimano Dura Ace® and XTR® Lockrings, it also fits several other lockrings as well.

The major diameter of the Park Tool BBT-7 is nominally 46.5mm, a ring can be no bigger than this size and fit the BBT-7. The minor diameter (at the notches), is nominally 41mm.
