The medium nose bridge comes preinstalled. It was slightly too wide, so I wanted to try the small size. When I removed the medium bridge, one side came out without too much fuss. However, the other side took an immense amount of effort to remove. My roommate and I have both lifted weights for years, and this little piece of plastic humbled us. My roommate got it off by "hammering" the goggles against one of our counters (I'm not sure the exact process he used). Somehow, both the bridge and goggles survived. Also, the small nose bridge is slightly too small, so neither of them fits just right. The goggles don't leak, but it is slightly uncomfortable.
