Park Tool USA Bbt-7

Omschrijving en details

The new BBT-7 Lockring Wrench is used for installing and removing the adjustable cup lockring used Dura-Ace and XTR Bottom Brackets (M950) using a left side lockring. (NOTE: XTR M952 and Dura-Ace 7703 cartridge bottom brackets use the BBT-2 only.)
The BBT-7 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. The major diameter of the tool is nominally 46.5mm. A ring can be no bigger than this size and fit the tool. The minor diameter (at the notches), is nominally 41mm.
NOTE: The 2004 Dura-Ace, XTR, and XT use the BBT-9.
