Review on Black Ops BB Conversion Kit: Effortlessly Transition from American to Euro, in Sleek Black by Will Rahman

It worked very well. Make sure you line up the holes before pushing them in. I had a weld at the bottom so I lined up the arrows with that. Push in one side (left and right are labeled there too!) and then push in the other side with the screws, tightening each a few turns so you push them in. My mount is 65mm. The bottom bracket needs to be 68mm so I used shims on the bottom bracket. Making Wheels 1mm Cassette/B-Gasket (Pack of 10). Also start with the plastic side of the bottom bracket first, this will help you screw it straight in (I was cross-threaded the first time and had trouble restarting before doing this. I put this on my '82 Schwinn Continental 10 Speed, add triple gear in front and it works great, reliable product.
