Bottom Bracket Tap Holder – 1697.2/4, 1698.2/4
- Used to convert our bottom bracket tap system to either BSA or Italian threading
- Two tap holders required
Two handles, two of these tap holders, a set of taps, and a tap frame is all you’ll need to build a bottom bracket tapping tool. If you’ve already got a BSA or Italian version, you’ll just need the appropriate taps and tap holders to switch between the two; the frame and handles are the same.
