Park Tool BBT-79 Bottom Bracket Tool: The Essential Tool for Bicycle Maintenance

A Gunn: The right tool for the job is so important. Dont you dare use channel locks or vise grips to remove the BB. Get this and save yourself the frustration.

Simple User: The SRAM DUB bottom brackets use a different spline from their older ones, so I needed a new tool. Park makes great tools and this is no exception. It works with a torque wrench so you can install the BB correctly.

Jeff B: Can't believe I have to buy yet another BB tool (I think I have 6 different ones at this point), but what are you going to do?

This worked fine for my SRAM BB.

JetBlast: I normally use a half crescent tool to remove my external bottom brackets. It's very handy for what they are and works well. I did have one minor headache with the crescent bottom bracket tools. They could slip off the external bottom bracket and damage it in the process. Luckily, Park Tool created a ratchet tool to fix this problem! The BBT-79 was designed primarily for SRAM DUB 46mm bottom bracket removal and installation. I used it with my ratchet and it made my job so much easier. I definitely recommend these bottom bracket tools over the crescent versions.
