Thought I start a thread where we could post cool tools and mods.

Yesterday I got a bike with a 10 speed record (the new 10 speed not the old one we all love) bottom bracket and rear cassette. The tool for removing this is a BBT-5 from park, but I had an old FR-1 that worked on the rear cassette just fine and with a lot of big drilling to enlarge the axle hole to fit over the bottom bracket stud I got the bottom bracket out smooth as pie as well!

I want to invent a "funny bike spline" universal tool someday.
