I just rebuilt the BB on my Aerospace GP. Going to be a week or two the way the weather is going, until I get started. At least I have a complete bike to work with. The decals are kind of shot. I also have a chrome fork to install. A very big BTW......An automotive bearing numbered 103-CC is an exact match for the original, and usually comes with a rubber seal instead of metal like some. It feels tight and smooth, smoother than some cartridge BB's I've installed. Can't wait for the first ride!,,,,BD
