Park Tools XTR/Dura Ace BB Lockring Wrench
Park Tools XTR/Dura Ace BB Lockring Wrench: The new BBT-7 Lockring Wrench is used for installing and removing the lockring used on 1998 and 1999 Dura Ace and XTR Bottom Brackets (M950). 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 Dura Ace and XTR Lockrings, it fits several other model and brand of lockrings as well.
