I had a really hard time trying to remove the bottom bracket fixed cup from my friend’s Elvish French bike. I replicated Sheldon Brown’s fixed cup removal tool, although my local hardware store did not carry any 5/8″ bolts, so I had to resort to a 1/2″ threaded bolt. I believe that I have made two improvements to the tool, which I’ll detail below.
My 2014 Specialized AWOL came with an FSA Omega MegaExo 19 triple crank and an FSA BB-4000 bottom bracket. I bought the bike in October and in March I started thinking about doing some post-winter maintenance. One of the things that I wanted to do was remove and examine the bottom bracket. Since I was not familiar with outboard bearing bottom brackets, I did some research about the BB-4000 bottom bracket, and here is what I found out.
