5.0 out of 5 stars Great Bottom Bracket! I bought this as a replacement bottom bracket for my homemade fixie. While the cartridge is clearly marked as to what side is what (good) and the fit was tight, the teeth for the bottom bracket wrench were fairly shallow and the tool kept coming out.

Why are threaded bottom brackets better?

Is pressfit better than threaded?
Pressed-in bearings are simpler to install and replace, and press-in BBs are less costly. More important, though, is that carbon construction can produce a beautifully precise press-in interface, but it does not lend itself well to threads, so typically, a threaded-aluminum insert is bonded into the BB shell.
