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

I installed this BB conversion kit on my late 80's Schwinn cruiser so I could later rebuild an engine that required a three piece crank type. The install went very smoothly from the second time on, as I flipped from left to right the first time. I didn't really care, although I could see it could get a bit more routine without agility. I've been using a standard Shimano bottom bracket cartridge for a few hundred miles with no problems. There was no metal on my bike to sharpen, but I think I got lucky. It is largely unobtrusive, protruding just a few millimeters from the stock bottom bracket shell on each side, and has the same outside diameter. everyone, if it happens that I have to do another transformation, I will not hesitate to use another one of them.
